摘要
为探明诱发唐山矿冲击地压的主要因素,采用层次分析法构建了包含3个层级的计算矩阵,其中最顶层为主控性指标层,中间层包括地质力学因素、回采工艺过程和巷道支护3个方面,最低层包含埋藏深度、地质构造等14个影响因素,根据计算结果对这些因素进行影响程度排序.研究结果表明:影响唐山矿冲击地压发生的主要因素有水平应力、地质构造、工作面布置、推进速度,这4个指标的权值和为0.619,符合冲击地压主控性指标要求.
In order to identify the main influencing factors that induce rock burst in Tangshan Mine,the analytic hierarchy process was adopted to build calculation matrix of three levels.The top layer is the main control index layer,the middle layer includes geomechanical factors,mining process and roadway support,and the lowest layer includes 14 influencing factors such as burial depth and geological structure.The influence degree of these factors is sorted according to the calculation results.The research results show that the main factors that affect the occurrence of deep mine rockburst in Tangshan Mine include horizontal stress,geological structure,working face layout and advancing speed.The weight sum of these four indexes is 0.619,which meets the requirements of the main control index of rockburst.
