急倾斜煤层短臂综采工作面水平分层综采放顶煤采煤法,要实现高产高效有一定的难度;在苇湖梁煤矿+579E1WB_(4+5)急倾斜煤层短臂综采放顶煤开采工作面,通过优化采煤工艺和劳动组织,合理确定开采技术参数,开创了最高日产2563t,回采率达到85%的效果,实现了急倾斜煤层综采放顶煤(一井一面)的安全高产高效开采,为集团公司探索并最终实现“四矿联合”生产模式和成功打造千万吨急倾斜高阶段放顶煤开采(技术)的矿区的提供了有力依据。
In the steep inclined coal seam short-leg fully mechanized coal mining face with horizontal stratified mining and mining method, it is difficult to realize high productivity and high efficiency. In the short-leg fully mechanized top coal caving of +5109E1WB_ (4 + 5) steep coal seam in Weihuliang Coal Mine, Mining working face, through optimizing coal mining process and organization of work, reasonably determining mining technical parameters, creating a maximum of 2563t Nissan, recovery rate of 85% of the effect achieved in steep seam safety of fully mechanized top coal caving (one side) High-yield and high-efficiency mining has provided a powerful basis for the group companies to explore and finally realize the “four-coal joint” production mode and the successful mining area of 10 million tons of steep high-stage inclined top coal caving (technology).
