摘 要:针对深部开采“三高一扰动”条件下煤矿易发生冲击诱导突出耦合灾害问题,提出了一种耦合灾害钻孔-切槽综合防治技术。基于致灾过程应力传递规律分析和MATLAB数值计算,确定了冲击诱导突出耦合灾害发生的本质原因。通过FLAC3D数值模拟方法依次开展了巷帮钻孔、底板切槽和钻孔-切槽综合防治3种技术治理效果研究。研究表明,钻孔-切槽综合防治技术可有效削弱巷道围岩与底板应力集中,达到防治冲击诱导突出耦合灾害的目的。Aiming at the problem that the coupling disaster of impact-induced outburst is prone to occur in coal mine under the condition of"three high and one disturbance"in deep mining,a comprehensive prevention and control technology of drilling-grooving for coupling disaster was proposed.Based on the analysis of stress transfer law in the disaster process and MATLAB numerical calculation,the essential cause of the impact-induced outburst coupling disaster was determined.By means of FLAC3D numerical simulation method,three kinds of technical treatment effects were carried out successively,namely,hole drilling,floor grooving and drilling-grooving comprehensive prevention and control.The research show that drilling-grooving comprehensive prevention and control technology can effectively reduce the stress concentration of roadway surrounding rock and floor,and achieve the purpose of preventing the coupling disaster of impact-induced outburst.
