上提面风氧化带巷道支护技术

Support Technology of Roadway Passing Through Efflorescent Oxygenized Belts

针对顾北矿1242(3)上提工作面回风巷在风氧化带中的支护难题,结合实际地质条件,采用先锚索网支护加巷帮走向锚索,然后再套架U型钢梯形棚,最后喷注浆加固巷道围岩的方法,形成多种形式的联合支护,在现场实际应用中起到了良好的支护效果,实现了安全快速掘进,最终达到工程应用要求。

In order to overcome difficult problems that the road pass through efflorescent oxygenized belts in 1242（ 3）working face of GuBei coal mine,combine reality geological conditions,adopt the following way,fist support anchor net and roadside anchor cable,then set ladder shed,last grouting control the deformation of roadway,combined supporting is formed by diversified forms,this is a good supporting effect in the practical application,safety and quickly tunneling is achieved,it can satisfy the use requirement engineering.
