川煤集团达竹铁山南煤矿成功破解位于该矿的国内首个特大倾角急倾斜综采工作面——4013k26工作面移架难题,为该面的顺利回采打下了坚实的基础。该工作面地质条件复杂,平均倾角达52°以上,且顶板破碎,移架是个大难题。本次移架过程为:移架前,停止割煤机和刮板运输机运行,并将邻移架操作阀把手转置于推溜位置,防止因刮板运输机拉回影响移架步距和循环进度;移架时,采取一处拉架方
Sichuan Coal Group Tatsu Tushannan Coal Mine successfully cracked in the mine’s first large dip steep inclined fully mechanized coal face - 4013k26 face movement problems, for the smooth mining face laid a solid foundation. The geological conditions of the complex face, the average dip angle of 52 ° or more, and the roof broken, moving the frame is a big problem. The relocation process is as follows: before moving the rack, stopping the coal cutter and the scraper conveyor to operate, and shifting the handle of the adjacent rack to the push-slip position so as to prevent the scraper conveyor from being pulled back and affecting the moving distance and circulation of the rack Progress; move frame, take a square frame
