摘要
采用MTS对山东某矿3下煤进行了煤层冲击倾向性试验研究,通过对冲击能量指数、弹性能量指数和动态破坏时间3个煤层冲击能量指标的试验和分析,得出煤层具有较弱的冲击倾向;结合实际采矿条件,应加强冲击地压的预测预报,以保证矿井的安全生产。
Experimental study on burst tendency of coal seam was conducted in a coal mine in Shandong Province with MTS. Through the experiment and analysis of the impact energy index, elastic energy index and dynamic destruction time of three coal seams, it was concluded that the coal seam has weaker burst tendency so it is necessary to strength the prediction of rock burst in the light of the actual mining conditions so as to guarantee safe production of the mine.
