摘要
为了取消区段煤柱,在回采过程中进行沿空留巷。本文结合15103工作面现场条件,采用运输巷巷旁充填工艺。现场试验表明:充填体能够有效支撑顶板,沿空留巷可极大缓解采掘接替紧张的状况。
In order to cancel the section coal pillar,the gob-side entry is retained in the mining process.Combining with the site conditions of 15103 working face,this paper adopts the filling technology beside transportation roadway.Field tests show that the filling body can effectively support the roof,and retaining roadway along goaf can greatly alleviate the tension of mining replacement.
