"IntroductionMANY PAPERS presented on developments in the Canadian Petroleum Industry •during the past few years have commenced with this general sentence: ""The past year has been a record •one for the oil industry in Canada, with new records being set in nearly all phases •of exploration and development ,activity"". This sentence applies equally well to 1951. It is not possible to outline all the details of the broken records in exploration, development, and production but general comparisons can be made. There are several significant developments that have stolen the spotlight during 1951, some of which were foreseen in 1950 and some which were not. Among the high-lights were the following:(1) The greatly •expanded activity in the search for gas, which was touched off by the new Alberta regulations covering gas leases and reservations.(2) The discovery of commercial oil production in the Williston basin of North Dakota and Manitoba, which will have far reaching effects on Canadian oil.(3) The greatly increased activity in northern Alberta, northwestern British Columbia, the southern Northwest Territories, Saskatchewan, and Manitoba.(4) The new discoveries in the general central Alberta area.(5) The granting •of a permit for an oil pipeline to the Pacific coast.(6) The arrival of Western Canadian crude in central Ontario.(7) The number of new refineries completed, commenced, or proposed.(8) The present •and proposed expansion in the petrochemical industry.Most of the remarks made on various exploration and development •activities will refer to Western Canada operations, primarily because the greatest •activity and the most significant developments have been there. Eastern Canada exploration and development operations were at a slightly higher level than in 1950."

"IntroductionIN THE preceding paper we have learned about Canada's resources of metallurgical coal. There is an adequate amount in Nova Scotia, a very large reserve on the eastern flank of the Rocky mountains, and a strictly limited supply on the Pacific coast. Added to these is an unknown quantity of coking coal in the Peace River district, at present rather isolated but possibly capable of industrial development in the future.The chief use of metallurgical coal is to make iron and steel. For this, an adequate supply of iron ore is required. So we should now scan the Canadian supply of iron ore, the possibility of its increasing use at home, and the probable markets abroad.Trade in iron ore tends to be international, as is the case with many other raw materials. The present tendency with iron and steel, in contrast, is to keep its manufacture within national boundaries, and there is no evidence that this will change much in the years to come. We should keep these two points clearly in mind when considering the disposal of iron ore from Canadian mines. We should remember, also, that the modern blast furnace and steel plant has such a large output that a correspondingly large population, reasonably compact, is needed to consume its products.Large Ore Supply in East, Small in WestCanada has now four major iron ore fields, well situated to serve adequately the eastern half of the country. Wabana .and Labrador are well placed to serve overseas markets and plants on the eastern seaboard and eastern interior of the United States and Canada."

Introduction For many years the immense deposits of bituminous sands of northern Alberta have been attracting the attention of our governments, engineers and .scientists ( 6). Undoubtedly these bituminous sands represent one of the greatest potential resources of liquid fuels in the world. However, their commercial development has been retarded by the complexities of the technological problem and by the economic factors involved in the processing of the sands. The technological problem has been attacked from several angles ( 2, 3, 1, 11), and cold water separation of bitumen is one of them. To the ore dressing engineer, the cold water process is of utmost importance since, by the use of standard ore dressing machinery, it accomplishes most efficiently and economically the separation of bitumen from bituminous sands. The significance of using ore dressing equipment was especially enhanced by the fact that the scientific principles which underlie the design of standard machines were demonstrated in the cold water separation process with an extraordinary clarity. This greatly facilitated the analysing of limitations and advantages of different machines during-the pilot plant investigations and helped to complete the investigations practically in the allotted time.

"IntroductionANY PLANT processing mined Athabaska oil •sand for the recovery of oil produces, as a waste material, about one ton of sand for every barrel of oil recovered. A disposal problem of major proportions is thus indicated. For a 100,000-barrel per day plant, provision must be made for moving .about 4,000 tons of sand per hour on a continuous basis to a tailings dump at least several thousand feet removed from the plant site.Of the many known ways of conveying solids on .a large scale, the hydraulic pipeline transfer method is becoming increasingly important because of convenience and economy of operation. It has been in use for many years in mill operations at metalliferrous mines for the disposal of tailings and as such was a natural outgrowth of •hydraulic sluicing (3). Pipeline transportation of mill concentrates has been adopted recently ( 1), wherein high-density solids are moved several miles by hydraulic pipeline. The flotation power of the water suspending the solids may be increased 'by addition of magnetite for the handling of ore in pipelines (8). Low-density solids such as coal have received considerable study for low-cost pipe-lining (2) and a successful operation with coal has been carried out in England with indications of considerable savings over other methods of transportation (9). Dredge operations are based on pipeline transportation for the dredged sol-ids, and the scale of pipelining there .has involved pipe sizes as large as 32-inch (6). However, the tendency has been to regard the pumping of solids in water merely as a simple method of transportation and little consideration has been given in the published literature to study of the most economical modes of operating .a pipeline."

"AbstractThe results of research into the fatigue properties of SAE 1080 carbon steel and nickel-chromium-molylbdenum steel for mining drill rods are analysed and described in detail.The effect of water corrosion on the fatigue strength of drill rods of these two steels in the as-rolled condition has ,been investigated and the beneficial influence of shot-peening on their dry and water-corrosion fatigue strengths determined by employing the method developed previously (1).Eight S-N curves for as-rolled and shot-peened mining drill rods under both dry and water corrosion conditions have been derived and their shape and relative position are discussed. The main features relating to field performance of the drill rods are analysed.Purpose of Research and Outline of ProgrammeDRILLING holes in rock and ore by means of drill rods attached to a pneumatic drill is a basic procedure required in mining operations. Detonation of explosives placed in these holes is at present the only practical method of breaking down the rock and ore.A drilling rod is supported by its bit end in the drilled rock. Its shank end, fixed in the drilling machine, transmits impact energy to the cutting edges of the bit. On the field performance of the drill rod depend a number of basic mining operations such as sinking, drifting, and stoping. The drill rod is there-fore regarded as one of the most important tools used in the mining industry."

"THE most recent estimate of minteable coal reserves in Saskatchewan was made by the Federal Royal Commission on Coal (1944- 6). Saskatchewan was then estimated to have some 24 per cent of the Canadian reserves and two-thirds of this is located in what is called the Souris-Estevan area, which lies in the southeast corner of the Province and border's on the International boundary. It is also estimated that there are some 61/2 million thousand-tons in this area of lignite coal which grades 8,000 B.t.u. or less and has a moisture content ranging from 30 to 33 per cent. Ownership of coal rights in the Province is widely dispersed between the Crown, individuals, and corporations, and a recent survey disclosed that 40 percent of ownership was vested in the Crown and 60 per cent in private individuals and corporations. Coal rights on Crown lands may be leased at an annual rental of $ 1.00 an acre. Under such leases, a royalty of 5 cents a ton is levied on all coal mined. A royalty of 7 cents a ton is levied on coal produced from lands where mineral rights were purchased from the Federal Government prior to the transfer of jurisdiction over natural resources to the Province, in 1931. An annual mineral tax of 50 cents per acre has also been imposed by the Provincial Government on all coals within a defined producing areas."

Introduction A very large part of the world's fuel resources are in solid form, as various grades of ?coal, but an increasing proportion of fuel demands on this Continent and else-where are having to be met by liquid fuels. Convenience and, in many cases, cost weigh heavily in favour of the liquid: fuels, and there are many fuel burning applications where the use of coal would be impractical, such as for automotive or air transport. By extrapolating the present trends one might conclude that, in future years in Canada and the United States, coal will be used only in a few power stations close to coal fields. If such a state of affairs should arise, it will obviously prove embarrassing to those accustomed to make their livelihood from the winning and marketing of coal, but it is perhaps not so obvious that it must also prove an embarrassment to the nation. The major reasons for this are two in number. Firstly, if present coal production is to be replaced by oil production, a large capital expenditure is necessary, which must inevitably be paid by the consumer; and secondly, in times of emergency, large amounts of oil fuels are required for military purposes which cannot be achieved with solid fuels. It is obviously unwise, therefore, to discontinue the use of coal for those non-military jobs that it can do. If we examine the major fuel markets we find that there are three: Domestic heating Steam generation Transport by air, sea, and land For domestic heating, the extreme convenience of oil, in spite of its greater cost, has captured much of the coal market.

"Dominion No. 17 Colliery, of the Dominion Coal Company, Limited, is located in the district of New Victoria, N.S., at the entrance to Sydney harbour.This Colliery was opened in 1882 to work a submarine area of the Harbour seam (see Figure 1). It was closed in 1921 and the mine, which has a make of water of approximately 250 gallons per minute, was allowed to fill.No. 18 Colliery, situated almost a mile to the east, was opened in 1938 to work the Phalen seam in this area with the intention, later, of driving a cross-measure tunnel to mine the section of the Harbour seam lying between No. 17 Colliery and the Princess Colliery of the Nova Scotia Steel and Coal Company, Limited.In 1945 it became necessary to open this area in the Harbour seam and a cross-measure tunnel was driven from the existing workings of No. 18 Colliery in the Phalen seam, which underlies the Harbour seam at a depth of 500 feet.The tunnel was started in 1946 and completed in 1948. The cost of opening this section, which contained only 6 1/2 million tons of coal, made imperative the recovery of all the available coal and precluded the maintenance of the large barriers that had been left in No. 17 Colliery for impounding the water, especially as the maintenance of these barriers would have meant the loss of 885,000 tons of coal, or 12.3 per cent of the whole tonnage available. Therefore, a study was made to determine the best means to dewater the 250 million gallons of water lying in the old No. 17 Colliery."

"IntroductionCARBONIZATION, gasification, and chemical utilization of coal are interrelated topics, which makes it difficult to review one without indicating its connection with the others. Hence, in Progress in Coal Technology, Series No. 5: Carbonization, reference was made to gaseous products recovered in the carbonization of coal, and .to a number of chemicals made from the tars, light oils, and ammoniacal liquors which are by-products of coal carbonization.In this, the sixth paper in the review series, prime consideration will be given to the complete gasification of coal to give a fuel for domestic industrial, or power purposes and a synthesis gas suitable for the manufacture of gasoline, Diesel oil, and chemicals. The hydrogenation of coal, an alternative source of liquid fuels and of chemicals, will be reviewed, as will be a number of processes for •the recovery of chemical products from coal by extraction and chemical treatment."

"AbstractSatisfactory mine drilling operations depend on the good performance of the drilling machine, and of what may be called the drill set, i.e., the following four elements: bit, attachment, drill rod, and shank end. The field performances of these four elements in the drill set are analysed and their service lives are compared. The most .common causes of service failure are reviewed and possibilities of increasing service life are discussed.The laboratory methods now employed for the simulated service testing of tungsten carbide bits, conical push-on and threaded .types of attachments, drill rods, and shank ends are described, and some results are discussed. The objectives of the research programme now being carried out •on the above mentioned elements are outlined.A number of mines in British Columbia, northern Ontario, and northern Quebec have been visited, and, with the co-operation of the C.I.M. Branches in these areas, meetings with representatives of the mining and steel industries concerned have been held. In this paper, the mechanical-metallurgical problems most frequently encountered and discussed during these visits and meetings are described and .analysed.IntroductionSUCCESSFUL mine drill operations depend to a great extent on• the satisfactory field performance of the four elements which form the mining drill set, shown diagrammatically in Figure 1.These important elements are:1. -The bit, which may be one of the following types:(a) Detachable tungsten carbide bit( b) Inserted rod bit, so called chisel bit( c) Detachable steel bit( d) Solid rod bit"

Introduction Many tables of nomenclature for igneous rocks have been introduced from time to time, and each has its strong proponents. As a result, any discussion of igneous? rocks is apt to prove confusing unless the names used for these rocks are defined. This ?became so obvious to a discussion group, formed by the members of the Geological Survey of Canada in 1948, that an attempt was made to establish a scheme of nomenclature that could be used by any member mapping anywhere in Canada. The writer was asked to co-ordinate the ideas presented by individuals in the discussion group, to arrange them in tabular form, and, later, to distribute copies of the resultant table to Canadian universities, provincial geological surveys, and some other geological discussion groups. Many useful suggestions and criticisms were received, were studied ?by members? of the original group, and, so far as practicable, were incorporated in the scheme of nomenclature. The result is the table presented here. This nomenclature of igneous rocks is at present being used by most members of the Geological Survey of Canada who are working with igneous rocks, and by some Canadian universities. We hope it will be found useful and be more widely accepted. With this idea in mind, certain principles were adopted in drawing up the nomenclature.

"SummaryThe results of this investigation indicate that the gold in the cyanide tailing of refractory gold cyanides is occluded in fused •particles formed during roasting. This conclusion was reached following microscopic examination of calcines produced at various furnace temperatures with different atmospheres, and a •comparison with calcines produced by decomposing samples of completely sulphated concentrate under conditions such that the maximum particle temperature varied between 6•50°C. and 1,100°C. This comparison showed that the particle temperature during a normal roast may be several hundred degrees higher than the furnace atmosphere, or that the fusion is associated with a low melting (950°C.) eutectic mixture of FeO and FeS.Because of the unavoidable particle fusion during a furnace roast, and because low particle temperatures are essential for gold extraction by cyanidation, aqueous medium oxidation under high oxygen pressures was studied. Gold recovery from calcines produced by this means was over 98 •per cent •compared with a maximum of 80 per cent from furnace calcines.IntroductionMANY arsenical gold ores are called 'refractory' because much ' of the gold cannot be satisfactorily extracted by cyaniding the raw ore or concentrate. Even when such ores are roasted to oxidize .the iron and arsenic and 'release' the gold, often 10 to 25 per cent of the gold present is lost in the cyanide residues."

"UNTIL the last few years, the collieries of the Dominion Coal Company, Limited, while highly mechanized as to the cutting and transportation of the coal, still relied on the hand-loading of coal from the seam onto face conveyors. In these circumstances it was possible to assure that no large proportion of extraneous materials would be loaded with the coal, and the product could be quite well cleaned for the market by screening and hand-picking.Within the past few years, however, the Company has introduced an intensive programme of mechanization which will result in the virtual elimination of hand-loading .of coal. It has been the experience of other producers that mechanical loading inevitably leads to a very large increase in the amount of impurities in the product. This is occasioned by the fact that, at least up to the present, all types of loading machines have relied on the coal being broken from the seam by under-cutting and shooting. In this operation, a certain amount of roof and pavement material inevitably becomes mixed with the coal and, since selective loading is impossible with a loading machine, all this foreign material is loaded out with the product."

"THE EXPANSION of steel capacity is seldom spectacular. It may be for this reason that the remarkable progress made in Canada has not been generally recognized. In 1950, Canada's output of steel ingots amounted to 3,270,000 tons ( l ), which is a ll8 per cent increase over the tonnage produced in 1939. It can therefore be readily seen that Canada's growth curve for steel production is climbing at a rate paralleling her growth as a nation. It is by no means •an exaggeration of its importance to consider the steel industry as the cornerstone in the economic structure of Canada's manufacturing activities. From the humble diaper pin to the giant members of massive bridges, fortifications, and other steel structures, steel accompanies us as a necessary and inescapable companion in our journey through life. The Age of Steel has a literal meaning, and refinements in the manufacture of the products of steel are adapting it to more and more varied uses as time passes.The integrated iron and steel works of Canada fall into two natural geographical divisions. One has its base on the Great Lakes and draws its supply of •coal and some of its ore from the United States. In this division lie the works of the Algoma Steel Corporation, at Sault Ste. Marie, at the junction point of lakes Huron, Superior, and Michigan; and the works of The Steel Company of Canada, at Hamilton, on lake Ontario."

"HistoricalBARYTES was mined in Nova Scotia as early as 1874 from a deposit at Five Islands, on the north shore of Minas Basin. The first record of the presence of the mineral at the Walton site appears in a report by Selwyn in l893, who states: ""Barytes in considerable quantity occurs in veins in lime-stones at Walton and Pembroke"". The exact site of the present workings was marked •on a map published by Fletcher in 1905.The economic •possibilities of this deposit, however, were not recognized until 1940, at which time we were at war with Germany, who up to that time had supplied 50 per cent of the world's requirements.At that time the Nova Scotia Department of Mines, recognizing the need for certain strategic minerals, induced Canadian Industrial Minerals, Limited, to send prospectors into 'the area to look for manganese. No manganese deposits were found, but a deposit of barytes was directed to their attention, and exploration and development work on the occurrence was proceeded with.IntroductionThe south shore of Minas Basin between the Avon river at Windsor and the Stewiacke river at Maitland has long been known as a potential source of mineral wealth. It had attracted the attention of mineralogists and in the past had produced considerable tonnages of manganese ore and gypsum. Depletion of ore in surface and near surface deposits resulted in a dwindling production, until today only deposits of gypsum are worked."

On the recent trip from Vancouver to Calgary with the President, Mr. C. C. Huston, and yourself, I had the opportunity of outlining a plan based on the following: Among the aims of the Institute are, obviously, the fostering of the confraternity of those engaged in the technical and management fields of the mining and petroleum industries. This may be achieved in a number of ways, of which, to me, the interchange of ideas and experience between different parts of Canada and different sections and divisions of the Institute appears to be one of the most important. I think you and the membership as a whole are, and have been, well aware of this. The annual tour of the President .and Secretary, particularly their visits to Branches, shows this to be true. The interchange of ideas through the medium of the BULLETIN also illustrates the point; indeed, most Institute activities are directed along these lines. I am convinced that much more could be accomplished if it became financially possible to do so. Many able and fine men are, I think, willing and anxious to give their time and energy to furthering these phases of Institute activity, but it is unfair to expect them to assume as well the financial obligations involved. Specifically, I would suggest that the following could be done if sufficient funds were available:

"IntroductionA STRIKING FEATURE of the past twenty years has been the application of organized scientific and industrial research to problems of national defence and security and to the development of our natural resources. It has been shown that effective research improves public health, increases the productivity of land, makes mineral wealth available, and increases the efficiency and productive capacity of industry. Alberta is a region bounteously provided with a variety of natural resources, and the Province has entered into a period of unprecedented industrial development. There is, surely, a great opportunity to bring scientific research to bear •on problems associated with the development of these natural resources.I propose to spend a little time discussing the term 'research', indicating something of the various types of research and those fields which appear to •be the particular responsibility of government bodies. It seems logical, also, to outline the course of development .of industrial and scientific research in the English-speaking world during the past twenty-odd years.Research is investigation, examination, or enquiry, and involves the application of human thought, and actions, to the unfolding of new knowledge. That knowledge may assume a variety of forms. Fundamental knowledge may be new facts related to some form of matter, to motion, space, thought, and so on. Those engaged in applying the natural sciences have no monopoly on research as this term is equally valid for those engaged in obtaining, sorting, relating, and interpreting the facts of history, literature."

"IntroductionTHE PURPOSE of this paper is to present .a summary of the evidence given before the Petroleum and Natural Gas Conservation Board in support of applications to it for permits to export natural gas from Alberta.I will attempt to be objective in my statements, despite the fact that my main interest in the hearings before the Board was to advance the interests of my own clients, the Westcoast Transmission Company, Limited.The hearing of the export applications •commenced before the Board in January, 1950, with the .application of the Westcoast Transmission Company. Joint hearings were commenced in September, 1950, and completed on December 14th, 1951. The Board heard evidence in support of six applications for export, one application to build a gathering system in Alberta, and three interveners, the .latter being the City of Calgary, the local gas companies, .and the coal interests, including both operators of coal mines and the Unions.The evidence comprised better than 8,400 pages, over two million words, and occupied 92 days before the Board.The Interest in Natural GasThe natural gas industry is one of the newer industries. It is not yet twenty years •old. In the United States, the expansion •of pipeline facilities has been phenomenal in the last fifteen years, and particularly in the last three years, when a total of over two billion dollars was invested in pipeline facilities. There are approximately 250,000 miles of gas transmission pipelines in the United States at this time, with additional lines constantly being pressed."

"IntroductionNOTE.-All figures on the supply and consumption of coal in Canada cited in this paper were collected and reported by the Dominion Bureau of Statistics. The friendly and efficient co-operation of the officials of the Bureau. is the foundation upon which it has been my privilege to rely in the preparation of this and two earlier papers ( 1). My thanks are due also to our own staff on the Dominion Coal Board, who spared neither time nor effort in helping to prepare this paper.STATISTICS are comparatively dull and, to many people, coal statistics are duller than most. Coal is, however, the one basic mineral upon which our whole way of life depends and it may be well if attention is drawn to this fact by an occasional statistical review of the coal position in Canada. The recent furore over the oil and gas discoveries has so obscured the basic position of coal in many minds that a little basic coal information may be useful. It is for this reason that, for the third successive year, a factual survey of the coal position is being presented.In the previous papers (1) explanations have been given of the basic considerations in the preparation of these reports and some special phases of the overall picture have been examined. For these explanations, the earlier papers may be consulted."

"IntroductionASBESTOS FLOATS may be defined briefly as blends of air-borne particles of fibrous asbestos and dusts produced during the milling stages and collected by Cottrell precipitators, dust sheds, or bag-houses.The various grades of asbestos floats on the market contain fibrous asbestos particles ranging in length from microscopic to approximately 1/4-inch. The fines or dusts present in the floats are from 40 microns to 2 microns or less in cross-section.Airborne asbestos particles are of diverse length because they are collected at numerous places in the mill. There are: (1) dusts removed from dry rock storage bins, (2) dusts removed from rock and fiber screens, (3) particles from the tops of collectors, and (4) fines removed by suction from the processing equipment. Sometimes the airborne particles are kept segregated, so that there is a partial separation by gravity. This is accomplished by a series of dust chambers enclosed in a long, rectangular building. The longest and heaviest particles fall nearest to the air flow entrance, the smallest at a point farthest away and nearest the exit. Sometimes the air from the dust chamber building is passed through a series of bag-houses or electric :precipitators ,to collect the extremely fine particles which normally escape to the atmosphere."
