摘　　要：在复采煤层开采掘进过程中,受原小煤窑开采破坏,顶板的破坏程度千变万化,掘进工作面架棚支护时的顶板管理成为复采煤层开采的一项重要难题。基于此,运用了四种临时支护技术施工方法,研发应用各种条件下的临时支护方法,以实现复采煤层掘进工作面本质安全。During the driving process of compound coal seam mining,due to the mining damage of the original small coal mines,the damage degree of the roof is ever-changing,and the roof management during the shed support in the driving face has become an important problem in compound coal seam mining.In this paper,four construction methods of temporary support technology are used,and temporary support methods under various conditions are developed and applied to realize the intrinsic safety of heading face in compound coal seam.
