| 摘 要： | 本文根据陶压煤矿数年来大量观测资料,从造成冲击地压的多种因素中,分析确定了该矿深部构造应力场。并从自重应力、煤与围岩的物理力学性质、构造应力和采动集中应力等方面,论述了冲击地压的成因机理,这对开采深部煤层和有效地控制冲击地压提供了依据。

| Abstract: | On the basis of observation and experiment in TaoZhuang, the tectonic stress field in deep mining is determined in this paper according to the manefestations of impact ground pressure. Many factors affecting the impact ground pressure such as gravity stress, physical and mechanical properties of coal and surrounding rock, tectonic stress, concentrated mining stress and mining method are analyzed, Consequently, the mechanism of the origin of impact ground pressure is discussed. The results of this research proovide an important basis for the deep coal mining and the efficient control of the impact ground pressure. |
