摘要
为了提高资源的回收率,延长矿井的服务年限,减少掘进巷道的数量,消除回风巷道中上隅角瓦斯容易积聚超限的问题,新景矿在3^#煤3123工作面进风巷实施沿空留巷技术。该技术实施以来,因瓦斯超限而断电的次数明显减少,煤柱的回收使煤炭资源得到了极大的节约,成本降低,工作环境得到了极大的改善。
In order to improve the recovery rate of resources, prolong the service life of mines, reduce the number of roadways, and solve the problem of great accumulation of gas in the upper corner of the return airway, Xinjing Coal Mine implemented gob-side retaining technology in the 3# coal 3123 working face air entry lane. Since the implementation of this technology, the number of power outages due to gas overrun has been significantly reduced, the recovery of coal pillars has greatly saved coal resources, reduced costs, and greatly improved the working environment.
