深凹露天矿汽车运输功与台阶高度的关系

THE RELATIONSHIP BETWEEN THE TRUCK HAULING POWER AND THE BENCH HEIGHT IN OPEN—PIT MINES

从汽车对矿岩的垂直运输功和水平运输功两个方面，分析了台阶高度与汽车运输功的关系。认为采用汽主运输的露天矿，存在一个最佳台阶高度，使矿岩汽车运输功最小。

Starting from the ore—rock truck vertical hauling power and level hauling power，the relationship between the bench height and the truck hauling power is analysed． The optimum bench height which can minimize the ore—rock truck hauling power Is considered to be existing in open—pit mines with truck haulage．
