摘要
矿井工作面结束以后为了保护周围巷道,往往采区留设区段保护煤柱的方式结束,虽然客观上对巷道有一定的保护作用,但是对煤炭资源回收以及出支架期间顶板管理十分不利,经过长期实践和技术改革,实现了无煤柱结束工作面,并提高了工作面拆除支架期间顶板的可靠性。
After the working face of the mine is finished,in order to protect the surrounding laneway,the way of retaining the section to protect the coal pillar is often adopted.Although it has a certain protective effect on the roadway,it is very unfavorable to the recovery of coal resources and the management of the roof during the period of the support.After a long period of practice and technical reform,the working face ending without coal pillar has been realized,and it improves the reliability of the roof of the working face during dismantling the support.
