| 摘 要： | 本文通过现场地质调查及变形观测分析提出, 近百年来马步坎高边坡T33岩组中煤层普遍被开采过, 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-沉陷进一步发展的直接原因。如果没有新的采掘活动, 随着时间的推移, 最终将会自行稳定下来。

| Abstract: | Based on the site investigation of geology and analysis of observed deformation, it is shown in this paper that mining of T 3 3 coal beds in Mabukan slope over past hundred of years made upper rockmass tilt outward and subside. It is the direct reason why the rear edge of the slope top is tensiled and collapsed further. If there are no more activities of mining, along with the time going, the slope will be 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. |
