| 摘 要： | 某高速公路部分路段位于煤田浅部边缘地带，为有效评价煤矿采空区对高速公路路基及特大桥工程设施的潜在危害性，有必要查明区内采空区的分布范围和空间特征，确定采空区需要治理的程度，进而为采空区的优化治理方案提供决策依据。本文通过综合物探测量结合工程地质勘察，基本查明了煤矿采空区的分布规律和范围，首次在该区发现并确定了两条隐伏断层，详细分析了其在路基稳定性评价中的作用；明确了采空区的影响范围，从环境地球物理角度对煤矿采空区的治理提出了合理的建议。

| Abstract: | A part of the expressway studied is located at the margin belt of a hallow area caused by coal mining. Based on colligation of geophysical exploration and survey of engineering geology this paper gives the distribution of the hallow area and coal stopes. Two buried faults are found in the area, which is important, as suggestion, in analysis of the road base stability. The paper makes the suggestions to treatment of a hallow area caused by coal mining. |
