摘　　要： 西山煤电集团斜沟煤矿18503地表被黄土覆盖,该煤层厚度为4.5 m,由于顶底板千变万化,该煤层是典型的浅埋煤层。通过采用不同方法认真研究工作面压力,选用参数合理的液压支架及锚杆。本课题的成功研究对18503工作面以及后续工作面支护的选型和良好位态具有重要的参考价值。 The 18503 coal thickness of Xiegou coal mine is 4.5 m in Xishan Coal Electricity Group, and the surface is covered by loess. The coal seam is a typical shallow coal seam, and the roof and floor changes greatly. Using different methods to analyze the working face pressure and selecting the reasonable hydraulic support is and bolt of certain guiding significance for the support selection of the working face and the subsequent working face and ensuring the good posture.
