摘　　要：本文采用数值模拟、相似材料模拟试验等方法研究极薄下保护层钻采上覆煤层应力和变形规律,并与崔庙煤矿现场工业试验结论进行对比,验证了数值模拟与相似材料试验的正确性,其可以为极薄煤层首次开采保护层现场应用提供设计指导。In this paper, the numerical simulation and similar material simulation method were used to study the overlying coal seam stress and deformation rules of the extra thin protective layer drilling and mining, and comparing the results with the industrial test results in Cuimiao Coal Mine, to verify the correctness of the numerical simulation and similar material test, which provided the design guidance for thin seam first mining protective layer.
