摘要

根据Hoek-Brown准则,采用Roclab1.0软件对岩石力学实验参数数据计算,获取矿体和围岩的岩石力学参数,在此基础上运用FLAC3D数值模拟铅锌矿山矿体回采后,采空区围岩及巷道最大主应力、竖向位移、塑性区的变化情况,判定铅锌矿体回采对现有巷道的影响,最终为现场采空区治理提供相应的理论依据.

Abstract

According to the Hoek-Brown criterion,the rock mechanics parameters of ore body and surrounding rock are ob-tained by using the software Roclab1.0 to calculate the experimental parameters of rock mechanics.On this basis,FLAC3D is applied to numerical simulation of the changes of the maximum principal stress,vertical displacement and plastic zone of surrounding rock and roadway in goaf area after mining of ore body in lead-zinc mine.To determine the influence of lead-zinc ore body mining on the existing roadway,and finally provide the corresponding theoretical basis for the field goaf treatment.
