| 摘 要： | 本文根据相似模型原理,针对新疆阿舍勒铜矿具体地质条件,采用室内相似模型实验研究了采用不同结构参数的VCR采矿方法采场的稳定性。基于弹性介质平面应变的假设,分别模拟了采场结构参数为10 m、12 m、15 m时的矿房稳定性。实验研究结果表明,在现有生产地质条件下,阿舍勒铜矿采场跨度10 m时是稳定的;在12 m时,采场冒落到一定高度会稳定;在采场跨度达到15 m时,采场将会出现不稳定垮塌。实验结果可为VCR采矿方法采场结构的优化提供指导性意见。

| Abstract: | A laboratory physical scale modeling the VCR stope at Ashele copper mine in Xinjiang has been performed to examine influences of different spans on the stability of stope,aiming to find the optimum span for the stope.3 stopes were modeled,with span of 10 m,12 m and 15 m,respectively.Testing results indicate that under current geological conditions at Ashele copper mine,the VCR stope with 10 m span is relatively stable and safe for production,and the stope will ultimately stay stable though its roof may cave... |
