综采工作面断层预掘巷的设计及应用

Design and Application of Faults Pre-driven Roadway at Fully Mechanized Face

双鸭山矿业集团公司双阳煤矿在地质构造复杂综采工作面采取预掘中间巷(断层预掘巷)的方法,实现了综采面连续推进,减少了采煤搬家次数,提高了煤炭回收率,节省了资金。

The way of pre - driven middle roadways （faults pre - driven roadways） was adopted at the fully mechanized face with complicated geological structure. The continuous propulsion was realized. The moving frequency of mining was reduced. The coal recovery was raised. The funds were saved.
