正升煤矿采煤工艺的分析和选择

Analysis and selection of coal mining technology in Zhengsheng coal mine

介绍了大采高一次采全高、人工假顶分层开采和综采放顶煤采煤工艺的适用特点,结合正升煤矿的采区布置、煤层赋存特点,通过分析正升煤矿煤层开采深度、煤层顶底板强度、煤层厚度及煤层结构条件,确定采用综采放顶煤采煤法作为该矿的采煤工艺,可为同等条件下煤矿选择采煤工艺提供借鉴。

The paper introduces the characteristics and applicable conditions of full-seam mining technology, artificial roof slicing mining technology and fully mechanized caving mining technology. Based on the mining area layout and coal seam occurrence characteristics, combined with the mining depth, the strength of roof and floor, the thickness of coal seam and the structural conditions of coal seam in Zhengsheng coal mine, the fully mechanized caving mining method was determined as the mining technology,which can provide reference for 1he coal mine to choose the mining technology under the same condi- tions.
