摘要
以夏蓉高速湖南境郴宁高速公路k179+870~k180+030段路基压覆龙潭煤矿采空区作为研究对象,通过对现有的地质勘查资料及物探成果的综合力学分析及评价,再运用数值计算模拟采空区的覆岩移动规律、地表变形规律,计算已有采空区可能引起的地表变形范围和变形量,进而对k179+870~k180+030段采空区稳定性、煤柱保护范围及与高速公路的影响进行分析评价。
Make the strip district pressured overlying by highway subgrade in hunan province as the research object,through the comprehensive mechanics analysis and evaluation on existing geological exploration data and geophysical exploration,using numerical simulation to get movement regularity and surface deformation law,calculation the surface deformation range and deformation cause by mine goaf.As a conclusion the stability of goaf coal the scope of protection coal-pillar and the influence of highway are analysised and evaluated in the paper.
