露天矿山电铲卡车优化设计

Optimization Design of Forklift and Truck in Open-Pit Mines

在露天矿开采中,增加露天矿经济效益的主要途径是提高大型电铲、卡车的利用率。在考虑露天矿一个生产班次(8 h)内铲位产量、卸点需求、道路运输能力以及电铲装车、卸点吞吐量的能力等约束条件下,针对提高大型设备利用率的目的,提出分别以最少总运量(t.km)、电铲数量和最少卡车数量为目标,建立线性整数规划(0-1规划)模型和非线性规划模型,并给出相应快速算法,结合某矿山实际给出算例对其进行了验证,并分析了目标模型可进一步优化的方向。

It is the major channel to increase the economic efficiency by improving the utilization ratio of large forklift and truck in the open-pit mines. Considering the conditions such as the production （8 hours）with the shovel-bit output,the demand for unloading point, the road transport capacity, the power shovel loading, the capacity of the unloading point etc. in the open-pit mines,the target to use the least total volume （ton-kilometers） ,the least number of forklifts and trucks is proposed to improve the utilization ratio of large-scale equipments. The linear integer programming （0-1 P）model and the non-linear programming model are established, at the same time the corresponding fast algorithm is given. A case study of one mine verifies the algorithm,and the direction of target model which can be further optimized is pointed out.
