王家营青利煤矿开裂山体稳定性分析
|
摘要
文中从王家营青利煤矿1304工作面地质采矿条件、地表裂缝分布情况、地表变形特征、地面变形观测结果等多个方面分析论证了矿区开裂山体的稳定性及山体出现滑坡和崩塌的可能性。最终得出"地表裂缝虽然发育,但开裂山体不会发生整体滑坡,仅在局部陡崖地段发生崩塌"的结论。文中的分析结果对贵州山区矿山开采引发的地表移动变形研究具有一定的参考价值。
In the paper,the stability of the cracked mountain body and the possibility of landslides and collapses in the mining area were analyzed and demonstrated from the aspects of the geological mining conditions,the distribution of the surface cracks,the surface deformation characteristics and the observation results of the surface deformation in1304 working face in Wangjiaying Qingli Coal Mine. Finally,the conclusions were gained that although the surface cracks were well developed,the whole landslide would not occur in the cracked mountain body,but collapse would occur only in the local cliff area. The results had a certain reference value for the research on the surface movement and deformation caused by mining in Guizhou mountainous area.
