现代构造应力场与矿井冲击地压
|
摘要
抚顺老虎台矿是我国发生冲击地压较早、次数较多的矿区之一。文中以地质动力区划方法查明的各级活动断裂为区域构造格架，将老虎台井田简化成由１０条断裂带组成的平面弹性模型，编制了应力计算软件。得出了浑河断裂是一条活动断裂，蠕滑活动是其主要活动方式。它的断裂带及与之平行的Ｆ＿１断层形成的构造应力区对矿区应力状态起主导作用，采动影响是导致该断裂带内构造应力释放、产生冲击地压的诱因的结论。
Laohutai Mine in Fushun is one of the mines in which the impact ground pressures have taken place earlier and more frequently.This paper regards all active fractures found out by geodynamic division method as regional tectonic framework,and simplifies Laohutai mine field into an elastic plan model with 10 fracture zones and compiles stress calculating software.It concludes by calculating that Hunhe fracture is a active fracture and its main movement is creepage,the tectonic stress field formed by the fracture zone and Faule Fl in parallel with it plays a leading role in mine stress state mining effect is the inducing genesis which leads to the release of tectonic stress in the fracture zone and occurrence of impact ground pressure.
