改进露天开采工艺最有发展前途的方向之一是增大露天矿剥离台阶的高度。增大台阶高度可以使开采作业集中,从而提高主体采矿运输设备的效率,减少运输水平总数,并因此使露天采场内部道路的建设费用和维护费用下降。对用各种高度台阶开采矿岩的经
One of the most promising directions to improve the open pit mining process is to increase the height of the pealed steps of the open pit mine. Increasing the height of the step can concentrate the mining operations, thereby increasing the efficiency of the main mining and transportation equipment and reducing the total level of transportation, and thus reducing the construction and maintenance costs of the internal roads in the open pit. On the use of a variety of steps to mine rock
