中文摘要: 中色卢安夏铜业有限公司巴鲁巴铜矿矿体北翼陡倾角矿体目前已基本回采完毕,余下资源主要为缓倾角矿体。针对缓倾角矿体的回采,尝试过多种采矿方法,但均未收到良好的效果。目前使用单分段崩落法,此采矿方法主要问题为采矿贫化率过高。为解决此问题,探求合理的采场结构参数,本文利用有限元软件ANSYS对采场不同布置方式时围岩的应力变形状况进行了分析,对计算结果进行比较,最终确定了合适采场结构参数,即凿岩道布置在矿体下盘3m的位置,凿岩道间距布置为12m。
Abstract:The north limb of CNMC Luanshya Copper Mines PLC Baluba Copper Mine which has a steep inclination orebody has already mined out. The remined area is gentle inclination orebody which is hard to recovery. Many mining methods have been tried but little was efficient. At present, the single level caving method was used, which has a problem of high dilution. In order to solve this problem and make the stope arrangement more favourable for mining, the stress and deformation condition in surrounding rock was analyzed in different stopes arrangement method by using large-scale finite element software ANSYS, compared with the simulated results,we got the optimal structure parameters of stope, with the drilling drive under the footwall of orebody for 3m and the distance between the drilling drives is 12m.
