【摘要】 矿井冲击地压预测的准确性和可靠性,根本上取决于对区域构造应力和地质断裂构造活动的研究水平。本文利用地质动力区划方法确定了乌东井田内的五级断块图,分析了井田内断裂构造运动和能量变化,结合乌东矿以往冲击地压显现,最终得出Ⅰ-1、Ⅳ-2、Ⅳ-3、Ⅳ-4等断裂对乌东煤矿影响显著。更多还原

【Abstract】 Accuracy and reliability of predicting mine rockburst rely on the research level of regional tectonic stress and activity of geological fracture tectonic. This paper applies methods of geo- dynamic divisions and determines five classes fault blocks in Wudong coal mine field. Analysis on tectonic movement and energy changes of faults,combined with the past rockburst behaviours of Wudong coal mine,we ultimately get that faultsⅠ- 1,Ⅳ- 2,Ⅳ- 3,Ⅳ- 4 etc have a great effect on Wudong mine.更多还原
