露天煤矿动态纵向组合桥布置参数优化

Optimizing on Setting Parameter of Dynamic Vertical Combination Bridge in Surface Coal Mine

针对大型特大型露天煤矿工作线较长、内排运距过大的情况,运用露天采矿学基本原理,在迈步式中间单桥的基础上,提出了一种新的减小内排运距、降低运输成本的方法-动态纵向组合桥运输方法,并通过建立数学模型,得出了纵向组合桥的最佳服务范围、最优桥体层数以及最大经济效益。

According to the situation of long work line and oversize internal dump load distance in large open-pit coal mine, a method of dynamic vertical combination bridge mode based on the basic principles of surface mine and the method of stepped type single bridge in the middle of pit was put forward, and then, dynamic vertical combination bridge transportation mode, the best service scope, the optimal bridge inventory count and maximum economic benefit were obtained.
