Installing New Rail Haulage System At San Manuel

A first-class haulage level railroad was considered of prime importance during planning of San Manuel because successful operation of the mine would hinge heavily on the ability to move large tonnages of ore rapidly, safely and efficiently. These principles, plus certain techniques developed from experience on the 1475 level, are being employed in preparation of the 2075 level. At full production, twelve 23-ton trolley locomotives, each pulling fifteen 12-ton capacity ore cars, and fifteen 8-ton battery locomotives engaged in development, service and supply, will be in operation on the 2075 level 24 hours per day, seven days a week. More than 35,000 tons of ore will be transported every 24 hours. GENERAL DESCRIPTION The rail haulage system is designed to comfort- ably move twelve 180-ton payload trains per hour through the rotary dumps pulled by 23-ton trolley locomotives. The rail system is laid out as a simple double loop with one-way traffic of continuous haul as shown in the above diagram, and is comprised of about 30 miles of track on the 2075 level.
