一、前言 急倾斜采煤主要采用伪倾斜全充填缺口采煤法。而缓倾斜采煤主要采用滚筒采煤机、刨煤机等采煤机械和自移支架配套的长壁式采煤法。由于工作面出煤量大,其设备越来越向重型化方面发展。 急倾斜煤层除煤层倾斜较大的制约条件外、断层、褶曲、煤层厚度变化也很大,往往采区走向长度不大。所以缓倾斜煤层使用的采煤设备很难适应急倾斜煤层的机械化采煤方法。因此,应该加强急倾斜煤层的机械 First, the foreword Steep coal mining mainly adopts the full tilt-fill coal mining method. The gently inclined mining mainly adopts drum shearer, plow and other mining machinery and self-moving stent supporting long-wall mining method. Due to the large amount of coal on the work surface, its equipment is increasingly being developed in terms of heavy duty. In addition to the more inclined conditions of steeply inclined coal seam, the thickness of the fault, fold and coal seam varies greatly, and the length of the mining area is often not long. Therefore, it is difficult to adapt the coal mining equipment used in gently inclined coal seam to the mechanized mining method of steeply inclined coal seam. Therefore, the steep coal seam should be strengthened
