摘要
工作面超高巷道中,原来综采工作面顺槽经过整巷后个别地段超高,支护方式是采取支顺巷抬棚、构顶的方法进行支护。随着工作面的推进至超高巷道处时,端头维护和落山回柱放顶安全系数较低,很易发生安全事故,现用端头支架提高了其安全性,文章对端头支架的使用进行分析研究。
In ultra-high roadways, ultra-high segments appeared in the crossheading of original fully-mechanized mining face after roadway adjustment. Supporting methods included carrying tent and framing roof. When the working face advancing to the ultra-high roadway, safety coefficient of end maintenance and roof collapsing was rather low. Since safety accidents were liable to occur, end support was introduced. The paper studied the usage of the end support.
