摘　　要：煤层开采过程中,直接顶厚度对于综放工作面的安全开采有很大影响。本文应用UDEC软件分析采场直接顶厚度对端面稳定性的影响。通过对不同直接顶厚度影响下的端面稳定性分析,得出直接顶厚度与采场端面稳定性之间的数值关系,为煤矿安全开采提供了一定的理论基础。In coal mining process,the thickness of immediate roof has a significant impact on the safety mining of fully-mechanized caving face.In this paper,UDEC software was used to analyze the impact of immediate roof thickness on face stability.The relationship between the thickness of immediate roof and the face stability was obtained by analyzing the stability of face with different roof thicknesses,which provided theoretical basis for the safety mining of coal mine.
