摘要
韦家沟煤矿矸石山倚山堆积,堆载坡度与岩层倾角相近,堆积体本身物质结构又较为松散,同时由于矸石山改变了原来水系地貌,在大气降雨的作用下,矸石体容易出现滑坡失稳的危险。文章对韦家沟煤矿矸石山失稳的成因及滑坡机制进行了分析,在充分考虑大气降雨对矸石山稳定性的影响下对矸石山的稳定性进行了计算,并提出了相应的治理建议。
The gangue hill of Weijiagou Coal Mine is congested by mountain, the angle of gangue debris is close to the rock stratum tip, and the gangue matter structure is more loose, the intensity of failure plane is more lower. At the same time, the gangue hill has changed the natural river system and terrain configuration, in the effect of atmosphere rain, the gangue hill landslide of Weijiagou Coal Mine is more easy to appear. Considering the impact of rainwater and groundwater to the stability of gangue hill, the article has analyzed the cause of gangue landslide and calculated the stability coefficient of the Weijiagou Coal Mine gangue hill, and finally brought forward corresponding prevention and measurement suggestion.
