摘要
为进一步探究煤矿开采过程中的地质灾害防控工作的精准实施,结合某煤矿深部开采巷道存在岩爆风险的实际情况,从岩石力学的研究角度入手,基于现场实验对岩石物理学参数进行测试,并应用岩爆风险判据进行分析,确定当前该巷道处于中等岩爆风险水平.应用数值模拟分析方法,对巷道应力分布情况进行探究,确定了地质灾害防控的关键点.以理论计算方法对地质灾害防控措施进行优选,以期为后续现场支护作业方案提供参考.
Abstract
In order to further explore the precise implementation of geological disaster prevention and control during coal mining,combined with the actual situation of rock burst risk in deep mining tunnels of a certain coal mine,starting from the perspective of rock mechanics research,based on on-site experiments,rock physics parameters were tested,and rock burst risk criteria were applied for analysis to determine that the current level of rock burst risk in the tunnel is moderate.By applying numerical simulation analysis methods,the stress distribution of tunnels was explored,and the key points for geological disaster prevention and control were determined.Theoretical calculation methods are used to optimize geological disaster prevention and control measures,in order to provide reference for subsequent on-site support operation plans.
