摘要 薄煤层掘进工作面的煤岩分装分运是比较复杂的工艺。泉上煤矿在16煤掘进过程中探索应用了煤岩分掘、分运的施工方式,不断摸索与改进工艺,获得成功,在保证工效与进尺的前提下,有效回收了掘进过程中的原煤,提高了回采率,创造较好的经济效益。 The separation and transportation of coal and rock in the working face of thin coal seam is a relatively complex process. In the process of 16 coal excavation, The construction methods of coal and rock separation and transportation are explored and applied in Quanshang Coal Mine. Continuously grope and improve the process to achieve success. In the premise of ensuring the effciency and advance, effective recovery of coal in the process of excavation, improve the recovery rate and create good economic benefts.
