摘要
边角煤开采是煤矿生产建设中的一项重要内容,它对充分利用煤炭资源,提高采出率具有重要意义。南屯煤矿一采区西部1304工作面煤层赋存稳定、结构简单、围岩稳定,煤层平均厚度3.24m、平均倾角6°、硬度f=2-4,该工作面采用边角煤连续采煤机房柱式开采。本文探讨了该工作面边角煤连续采煤机房柱式开采技术的理论与实际应用,可为其他相似矿井的开采提供借鉴。
Edge horn coal mining is an important theme of coal mine' s produce and construction, it is an important significance to full utilization of coal resources and improve mining ratio. 1304 working face is in the west of No1 mining area of Nantun coal mine, bear stable coal seam, simple structure, stable wall rock, the average thick is 3.24 meters, average dip angle is 6~ and the average hardness is 2-4, this working face choose continuous miner room-and-pillar mining technology. This paper discusses theory and practical application of the continuous miner room-and-pillar mining technology and provide practical basis for the similar mine .
