摘要
大柳塔煤矿52505特大采高综采工作面切眼采用调斜回采工艺,通过第一阶段强制放顶,第二阶段10个循环完成了工作面调直,对大采高综采面调斜回采的安全技术措施进行了实践,效果较好。
In No. 52505 fully mechanized mining face with 7m large mining height in Daliuta coal mine,by using slope adjustment technology in the first stage of forced caving and second stage of 10 cycles,the adjustment of working face was completed and the safety technical measures for slope adjustment mining in fully mechanized mining face with large mining height were proposed.
