摘要
冲击地压是一种特殊的矿山动力现象,而冲击倾向性是煤岩体发生冲击地压的内在因素和必要条件。本文对湖西矿主采煤层进行了煤岩冲击倾向性试验研究,对冲击能量指数、弹性能量指数和动态破坏时间三个煤层冲击能量指标,以及弯曲能量指数的岩层冲击能量指标进行了试验和分析,获得该矿深部煤岩冲击倾向性评判结果,在此研究基础上,提出了湖西煤矿未来深部开采时冲击灾害防治对策。
Rockburst is a special mine dynamic phenomenon and tendency of rock burst is inherent factor and essential condition to the possibility of the rockburst of the rock and mine. This paper started with the experiment of coal burst tendency that was conducted in main mining coalseam in Huxi colliery. Through the experiment and analysis of the impact energy index, elastic energy index, dynamic destruction time of coal sample, and the Bending energy index of rock sample, the author found the judged result of tendency of rock burst for deep surrounding rock, by means of which the author also proposed the preventive and control measures for the rock-burst of the future deep mining exploitation.
