对近几年国内发生过的煤与瓦斯突出、冲击地压等典型动力灾害事故调研统计的基础上,对引起煤矿动力灾害事故的采场结构参数、地质构造等影响因素进行了研究分析。总结分析出采掘工作面的结构参数直接影响着动力灾害事故发生的临界条件,其中煤柱宽度影响着巷道与巷道之间的距离、工作面与附近巷道及工作面与附近临空区之间的空间位置关系,合理的确定工作面结构参数及其位置关系,使其在动力灾害事故发生的临界条件之外是急待解决的问题。
Based on the investigation and statistics of typical dynamic disasters such as coal and gas outburst, rock burst and so on, the influencing factors of the stope structure parameters and geological structure that cause coal mine disaster are studied and analyzed. It concludes that the structural parameters of mining face directly affect the critical conditions of dynamic disaster accident. The width of coal pillar affects the distance between roadway and roadway. The distance between working face and nearby roadway and working face and the adjacent freeboard The relationship between the spatial location and the structural parameters of the working face and its location are reasonably determined so that it is an urgent problem to be solved beyond the critical condition of a power disaster accident.
