摘　　要：针对山西晋煤集团阳城晋圣固隆煤业有限公司15号煤层四盘区浅埋区水文地质条件复杂的问题,通过地质调查、工程钻探、物探测井等综合探查手段,系统分析了浅埋区的地质构造、水文地质特征及煤层赋存情况。研究表明,浅埋区15号煤层埋深为38.35~81.00 m,厚度1.81~2.70 m,顶板导水裂隙带高度为31.7~42.9 m,主要充水水源为大气降水和顶板含水层,充水通道为煤层顶板导水裂隙。根据煤层埋深和导水裂隙高度,将浅埋区划分为重点防治区和一般防治区,提出了相应的防治水措施,并计算了保护煤柱的留设范围。研究结果为浅埋区安全开采提供了科学依据,具有重要的工程应用价值。In view of the complex hydrogeological conditions in the shallow buried area of the fourth panel of No.15 coal seam in Yangcheng Jinsheng Gulong Coal Industry Co.,Ltd.,Shanxi Jincheng Coal Group,the geological structure,hydrogeological characteristics and coal seam occurrence in the shallow buried area were systematically analyzed by means of comprehensive exploration such as geological survey,engineering drilling and geophysical exploration wells.The research showed that the buried depth of No.15 coal seam in shallow buried area was 38.35-81.00 m,the thickness was 1.81-2.70 m,and the height of roof water conduction fractured zone was 31.7-42.9 m.The main water filling sources were atmospheric precipitation and roof aquifer,and the water filling channel was the water conduction fracture of coal seam roof.According to the buried depth of coal seam and the height of water conduction fracture,the shallow buried area was divided into key prevention and control area and general prevention and control area.The corresponding water prevention and control measures were put forward,and the range of protective coal pillar was calculated.The research results provided a scientific basis for safe mining in shallow buried areas and had important engineering application value.
