摘要 本文通过对黄淮地区煤矿立井破裂的详细调查,分析了破裂井筒的水文工程地质条件及由于底含水泄入矿井,在底含及基岩风化带内产生渗流变形。本文首次明确提出黄淮地区井筒破裂的主因是松散沉积层底部渗流变形的结果。 Based on a comprehensive investigation of the shaft fracturing of coal mines in the Huanghai area,this paper analyzes the hydrogeological and engineering—geological conditions of the fractured shafts, the infiltrational deformation formed in bottom aquifers and the weathering zone of bedrock since the bottom water discharged into shafts. At the first time it is clearly put forward that shaft fracturing in the Huanghai area mainly results from infiltrational deformation in the bottom of regolith.
