摘要
根据对某石灰石矿的现场工程地质调查、评价以及室内岩石力学实验等,确立了该矿的岩体力学参数。采用三种理论方法以及数值模拟技术对该矿的隔离矿柱厚度、目前采空区及下步采场的稳定性进行了分析,得出该石灰石矿采空区下开采的结构参数为矿房15 m,房间柱12 m时,维持该矿上下分层稳定的隔离矿柱厚度应在12 m以上。
According to the engineering geology survey and evaluation of the area of a limestone mine and indoor rock mechanics tests,the rock mass mechanics parameters were obtained in this paper.The thickness of insulating pillar and the stability of the goaf at present were analyzed using three theory methods and numerical simulation.The result showed that when the chamber width was 15 m and the pillar was 12 m,the thickness of the insulating pillar should be more than 12 m.
