摘　　要：传统的急倾斜煤矿采煤方法为炮采加单体支柱铰接顶梁进行工作面支护,不仅煤炭产量较低,而且工人的劳动强度大,生命安全也难以得到保障。基于此,对某矿采用综合机械化开采急倾斜煤层进行分析研究。经实践应用,整体机械化综采设备的配套使用,使工作面开采作业变得更加安全可靠,避免了顶板的不稳定破断现象,极大地降低了煤矿工作面的生产成本,提高了煤炭产量,为急倾斜煤矿机械化开采提供了宝贵的经验。The traditional method of coal mining in sharply inclined coal mines is gun mining with monolithic pillar articulated roof beams for face support, which not only has a low coal yield, but also has a high labour intensity for workers and is difficult to guarantee their life safety. Therefore, an analysis and study of a mine using integrated mechanised mining of sharply inclined coal seams is carried out. After practical application, the overall mechanized integrated mining equipment is used, which makes the working face mining operation more safe and reliable, avoids the unstable breaking of the roof plate, greatly reduces the production cost of the coal mine working face, improves the coal production, and provides valuable experience for the national mechanized mining of sharply inclined coal mines.
