垮冒堆积体中救援通道位置及断面形状的模拟研究
Simulation study on rescue channel position and section shape selection for accumulation body of collapse-caving
摘要
Abstract
This paper is a response to the fault fracture zone with the greatest vulnerability to collapse-caving of roadways The first-of-its-kind study is focused on determining the optimization location and appropriate section shape of rescue channel by the numerical simulation analysis, coupled with a better insight into collapse-caving spatial characteristics of fault fracture zones, and accumulation characteristics of accumulation body, and border mechanics characteristics of accumulation body.The research demonstrates that the occurrence of natural balance arch tends to leave the collapse-caving of fault fracture zones limited to the elliptical line within;the boundary of the collapse-caving accumulation body is subjected to a force-a passive resistance force coming from the slope slip effect of accumulation body;and the attempt to reduce the disturbance to accumulation body and maintain the original natural stability of inner rocks, along with the consideration of the instability accumulation and forcible entry of support during rescue channel excavation requires that preferential location for the rescue channel be kept in the middle part of accumulation body area away from support accumulation, and in considering the appropriate section shape of rescue channel, a top priority be given to the straight wall arch and straight wall tip-top section shape.关键词
