复杂因素影响下深部矿产资源采矿方法优选

Optimization of Mining Methods for Deep Mineral Resources under the Influence of Complex Factors

通过对当前主要深部矿产资源采矿方法的分析,针对某工程地质及水文地质较为复杂的金属矿工程,对上向水平分层充填采矿法及分段空场嗣后充填采矿法进行对比分析。综合两种采矿方法的工程量及主要经济指标的对比结果,采用熵权法确定各指标权重,并最终确定采矿方法。本论文的研究具有一定的理论和实践意义,对于推动深部矿产资源的开发利用具有积极的促进作用。

Through the analysis of the current main deep mineral resource mining methods,a comparative analysis is conducted on the upward horizontal layered filling mining method and the segmented open pit subsequent filling mining method for a metal mining project with complex engineering geology and hydrogeology.Based on the comparison of the engineering quantity and main economic indicators of two mining methods,the entropy weight method is used to determine the weights of each indicator,and the mining method is ultimately determined.The research in this paper has certain theoretical and practical significance,and has a positive promoting effect on the development and utilization of deep mineral resources.
