煤矿区建筑物建设场地稳定性评价

Stability evaluation of building construction sites in coal mining areas

为分析煤矿区建筑物建设场地稳定性,以大阳泉公司煤矿井田范围内新建林场建筑物为例,通过对采空区覆岩破坏高度与建筑载荷影响深度的计算,分析了采空区对建筑物建设的影响;应用概率积分法对林场建设新址的地表沉陷状况进行了预测,给出了林场建筑物受采动影响程度;参考已有的采空区建筑相关规范,综合分析了林场建筑物建设新址地基稳定性。结果表明:林场建筑物搬迁新址东北方向地基基本稳定,适宜建设。

Taking the new buildings of forest farm building in the coal mine area of Dayangquan Company as an example in order to analyze the stability of building construction sites in coal mining areas,the depth of the overburden failure and building load were respectively calculated,and then the influence of building construction on the goaf was analyzed. The surface subsidence condition of the new building site was predicted by the probability integral method,and the mining impact of the forest farm building was given. According to the related specifications,the construction suitability of the new site was analyzed in forest farm. The results showed that the new site of the forest site relocation was suitable for construction in the northeast direction.
