| 摘 要： | 陈家河煤矿跑马岭山体因地下采空引起地面严重开裂.为解决跑马岭山体开裂原因和判定是否会产生滑坡或大规模崩塌,本文以采空塌陷机理分析并断定山体开裂的原因是采空塌陷变形造成的.又从山体地质构造、岩体结构研究,并采用有限单元数值分析证明了这种判断.为了进一步判定山体的滑、崩稳定性,采用软弱层极限平衡验算和结构面(赤平投影)组合判据以及工程地质比拟方法得出了"山体既不会产生滑坡,也不会发生大规模崩塌"的结论.经过5年的观测,证明了山体已经稳定.至今已整整20年,矿山仍安然无恙,也证明本文所介绍的评价采空区上山体(边坡)稳定的工作程序和方法是科学、有效的.

| Abstract: | This paper deals with the stability analysis on the goaf at Chenjiahe coal mine.The authors consider that the crack on the surface resulting from the ground mining does not affect the mountain stability. They draw this conclusion through definite unit digital analysis of the geological structure of the mountain and texture of the rock body,which is supported by the 5-year monitoring of the mountain and the 20-year record till today of the stable mining activities.It also means that the stable analysis method in this paper is of great value and effective. |
