| 摘 要： | 本文通过现场地质调查及变形观测分析后提出．近百年来马步坎高边坡Ｔ３３岩组中煤层普遍被开采．使Ｔ３３上部坡体发生向坡外的掀斜沉陷．是导致坡顶后缘拉裂一沉陷进一步发展的直接原因。如无新的采掘活动、随着时间的推移．最终将会自行稳定下来。并通过有限元计算．模拟再现了采掘与坡顶后缘拉裂一沉陷变形的发展。

| Abstract: | Based on the site investigation of geology and analysis of observed deformation, it is shown in this paper that mining of Tcoal beds in Mabukan slope over past hundred of years made upper rockmass tilt outward and subsids. It is the direct reason why the rear edge at top of slope is tensiled and collapsed further. If there are no more activities of mining, along with the time going, the slope will get stable by itself. FEM (finite element method) calculation simulated and reproduced the relationship between the development process of tension and subsidence of the rear edge of slope top and mining. |
