摘要
大柳塔煤矿作为神东一个特大型煤矿,历来在“降本增效”方面非常重视。大柳塔煤矿通过2-2煤分布式水库的建立、井下矸石排放置换、顺槽护巷煤柱部分回收技术及旺格维利采煤法的利用等方法,极大地提高了煤炭的回收率,降低了生产成本,推动了大柳塔煤矿节能减排工作的顺利进行,践行了低碳绿色的发展理念。
Daliuta coal mine,as a super large coal mine in Shendong Group,has always attached great importance to reducing cost and increasing efficiency.Through the establishment of distributed reservoir in 2-2 coal seam,and the use of underground gangue discharge replacement,partial recovery technology of coal pillars between coal mining faces,and Wongawilli coal mining method,Daliuta coal mine has greatly improved the coal recovery rate,reduced the production cost,promoted the smooth progress of energy conservation and emission reduction,and practiced the green and low-carbon development concept.
