摘要
针对目前煤矿孤岛工作面冲击地压类型复杂且治理缺乏针对性的问题,提出了"分类防治"的思路,围绕导致孤岛工作面冲击的高应力这一本质原因,并综合考虑覆岩运动、地质构造、开采、空间等因素,基于防冲对孤岛工作面进行分类;将孤岛工作面分为充分采动、非充分采动、充分-非充分采动、立体、"隐性"和复合型6种类型;将该分类方法应用于孤岛工作面采前冲击危险性评估,并根据评估结果对孤岛工作面冲击地压实施分类防治。研究结果表明:该分类方法可有效控制孤岛工作面冲击地压灾害。
Aiming at the problems that the rock burst of isolated island working face in the coal mine has the complex types and the control is lack of pertinence at present,the idea of“classified prevention and control”was put forward.Around the essential reason of high stress that caused the burst of isolated island working face,and comprehensively considering the factors of overlying strata movement,geological structure,mining and space,the isolated island working face was classified based on the burst prevention.The isolated island working face was divided into six types,including the sufficient mining,insufficient mining,sufficient-insufficient mining,stereoscopic,“recessive”and compound type.The classification method was applied in the risk assessment of rock burst before mining in the isolated island working face,and the classified prevention and control was implemented on the rock burst of isolated island working face according to the assessment results.It showed that the classification method could effectively control the rock burst hazard of the isolated island working face.
