摘要
露天矿的开采程序能否进行优化直接影响着矿山开采的总体经济效益,为了解决安家岭露天矿过芦子沟背斜开采程序问题,通过对安家岭矿地质条件、生产现状及排土空间等的分析计算,提出了"现采区工作线直推"、"直推+北部超前"和"L型扇形转向"三种技术可行的开采方案;在对上述方案中各项经济技术指标进行分析的基础上,将层次分析法与TOPSIS法相结合,先通过层次分析法确定选取的九个评价指标所占权重,再运用TOPSIS综合评价法对三个方案进行排序计算,最终确定"直推+北部超前"为最优开采方案。
Optimization of mining procedures in open-pit mine directly affects the overall economic benefits.In order to solve the problem of mining procedures in the case of passing the Luzigou anticline during the mining of the first mining area of Anjialing Open-pit Mine, through the analysis and calculation of geological conditions, production status, and dumping space, three technically feasible mining schemes are proposed, including direct push in the current mining area, direct push + northern advance and L-shaped fan steering.After analyzing the various economic and technical indicators in the above schemes, the weights of the nine selected evaluation indicators are determined through the AHP,and then the TOPSIS method is used to sort the three schemes, and finally the "direct push+northern advance" scheme is selected as the optimal mining plan.
