摘要
由于老巷周围岩层和支架受压力作用时间长,并且受到工作面超前支撑压力的影响,工作面通过时,往往维护困难,容易冒顶。特别是年久失修的老巷,维护更加困难。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。
Because the old lane surrounding rock and support pressure effected time is long,and under the influence of working face support pressure,fault fold beam column,roof breakage,when working face through,often cause pressure,maintenance difficulties,easy to roof caving. Especially the old,run-down maintenance more difficult. This paper a layer of roadway technology,methods of full-mechanized caving mining face was studied,solves the wear layer of roadway during the mining area coal roof management problems,and offers significant reference to the similar working face in mining.
