露天矿运输是开采工艺主要生产工序之一。据统计,运输系统的投资占矿山总投资的40~60%;运输成本占矿石成本的40%左右;运输能耗占全矿总能耗的40~70%。据“1982年黑色冶金矿山统计年报”资料,全国铁矿石总产量1亿吨中,露天开采占85.85%,其中重点企业铁矿石产量7870万吨,
Opencast mining is one of the major production processes of the mining process. According to statistics, the investment in transportation system accounts for 40-60% of the total investment in the mine; the transportation cost accounts for about 40% of the ore cost; and the transportation energy consumption accounts for 40-70% of the total energy consumption of the mine. According to the “1982 Statistical Report on Black Metallurgical Mines”, the total output of iron ore in China is 100 million tons, 85.85% of which is open-pit mining, of which 78.7 million tons are key iron ore production,
