摘要
综采工作面回撤时,设备列车头部与工作面之间的距离为230m左右,而确定的停采线距采区辅运大巷的距离为90m。因此,采取合理的措施保证工作面到达停采位置时有足够的空间停放设备列车对提高采区煤炭回收率,减少巷道掘进工程量,加快工作面回撤进度有重要意义。
The distance between the head of the equipment train and the working face is about 230m when the mechanized face is retreated, and the distance of the fixed stop-mining line is 90m.Therefore, reasonable measures should be taken to ensure there is enough space for parking equipment train to improve coal recovery rate of mining area, reduce roadway drivage, and speed up the working face retracement.
