摘要
铜坑矿92#矿体随着采矿生产的不断深入,地压活动进一步加剧,使空区周边采场出现应力集中,引起岩层开裂、破碎、沉降等现象,致使开采技术条件变差,采矿损失贫化逐渐加大,矿山经济效益严重下降,必须将在用的崩落采矿法进行转换。利用层次分析法与逼近理想解排序法构建AHP-TOPSIS评判模型,计算出4种备选采矿方法的综合优越度分别为61%,30.87%,53.91%,34.62%,从而确定机械化上向水平分层充填法最优。实践表明:AHP-TOPSIS评判模型在采矿方法优化选择中具有工程的可比性和实用性。
With the deeply mining,the ground pressure activities of 92#orebody of Copper pit mine intensify further,the stress concentration phenomenon appeared around the mined-out area,and the phenomenona of rock cracking,crushing and sedimentation are caused. So the mining technical conditions become poor,loss of mining dilution increases gradually,it is necessary to conduct conversion of the existing caving mining method. The AHP-TOPSIS evaluation model is established based on analytic hierarchy process method and the sorting method of approximation to the ideal solution so as to calculate the comprehensive superiority degree values of four alternative mining methods. The results are 61%,30. 87%,53. 91%,34. 62%. So the mechanization upward horizontal slice stoping and backfilling method can be regarded as the best one. The research results of this paper show that the AHP-TOPSIS evaluation model is suitable for optimal selecting of mining method.
