复合顶板大断面巷道支护技术研究和实施

Research and Application of Supporting Technology of Roadway with Large Cross Section Under Composite Roof

采用锚杆锚索木垛联合支护新技术对戊9-10煤层复合顶板大断面双切眼巷道施工,并进行了顶板离层监测、锚固力测试。结果表明,该技术能有效控制顶板下沉,实现了采面快速安装、投产,节省时间及费用,提高了劳动效率,具有广泛的推广应用前景。

The article expatiated on the combined supporting technology with anchor rob, anchor rope and wood crib in the roadway with large cross section under composite roof. According to the roof abscission layer monitoring and anchoring force test, the sinkage of composite roof in the roadway was controlled effectively. The installation of mining face can be ready quickly, and the woking face can be put into production rapidly,time and cost can be saved,and labor efficiency can be improved. All this have a bright prospect of application.
