摘要
针对特殊地质条件下的呆滞煤量,采取工作面停采线外延的方式进行开采,能够回收该范围的煤炭资源,提高矿井的煤炭资源回收率。本文介绍了综放工作面机头外延开采技术的应用与实践过程,对相似工作面的开采具有借鉴意义。
The dull coalreserves under special geological condition, mining working face mining stop line extension of the way to recovery the range of coal resources, coal resources to improve the recovery of the mine. This paper introduces the application and practice of fully mechanized top coal caving mining technology process of extension of working face head, similar to the working face mining has reference significance.
