Judging from the rapid pace of increased demands for mineral products, technological forecasting will become an increasingly necessary tool in mining. Even though the mining industry in 1966 produced more are than ever before, current extraction rates are only a fraction of what is expected in the later years of the twentieth century. If metal and mineral commodities continue to hold their respective and present share of markets, the prospect of coping with demands from a population that will double in the next thirty years can become an impossible task when viewed outside the limits of technological advance and change. Those mining companies that are doing little to develop new and expanding horizons for their operations cannot expect to survive. Nearly 90% of all metals and mineral products consumed last year was recovered by open-pit mining. This has placed great pressure on this segment of the industry which, consequently, has resulted in some spectacular developments. Already production rates at many places are dwarfing those of the Panama Canal and other well-known earth moving projects which are frequently identified as massive undertakings. With projects of this scale, the need for increased sophistication of engineering, planning, management and administration of modern mining installations has never become more apparent. The design of complete systems for the mine and plant that fit the mould of today's business and social environments is undergoing an evolutionary process.
