补送巷道回收综采工作面边角煤

随着煤矿综采工作面的推广,边角煤永久损失随处可见。杏花煤矿通过补送巷道回收了综采工作面边角煤,并在实施方案中改善采煤工艺,减少了巷道掘进量,为今后在复杂地质条件下如何减少综采工作面边角煤损失、提高资源回收率、降低回收资源成本积累了经验。

Recycling Bound Coal at Fully Mechanized Coal Face by Sending An Additional Roadway

With the promotion of the fully-mechanized coal face,the permanent loss of bound coal can be seen ererywhere.The bound coal at the fully mechanized coal face was recovered with the method of sending an additional roadway in Xinghua Coal Mine,and improving the mining technology to reduce the amount of roadway excavation in implementation plan.It can accumulate the experience on how to decrease the loss of bound coal at the fully-mechanized coal face,improve the rate of resource's recovery and reduce the cost...
