综放面过穿层老巷的研究与实践

Research and Practice of Fully Mechanized Caving Face Passing Through Layer Old Roadway

综放工作面在过穿层老巷期间,如果没有有效的顶板管理措施,容易造成老巷冒顶,从而导致工作面无法正常回采。该文主要对综放工作面过穿层巷道的技术、方法进行了研究,解决了穿层巷道区域煤层开采期间的顶板管理问题,对相似工作面的开采具有借鉴意义。

If there are no effective roof management measures during the period of passing through the old roadway in the fully mechanized mining face,it is easy to cause the roof of the old roadway to collapse,resulting in the inability of the working face to recover normally.This paper mainly studies the technology and method of the roadway in the fully mechanized top coal caving face,which solves the problem of roof management during the coal seam mining in the area of roadway,and has reference significance for the mining of similar working faces.
