Study on Stability for Intersection of Deep Soft Rock Roadway
Advanced Materials Research, 2011With the depth increasing continuously, more complicated of geological conditions, will make intersection in deep soft rock roadway is very difficult to support. In order to solve the intersection problem of difficult to support, combined with the third levels of the Fifth Coal Mine of Hemei, the coupling supporting design—anchor-mesh-cable + truss to ...

Study on the Supporting Technology of Complex Deep Coal Roadways
Advanced Materials Research, 2012Suffering from the effect of the high ground pressure, water spraying from roof surrounding rock or geological tactics such as faults or collapse columns, roadways used to have large deformation, even lead to caving accidents. Based on the supporting research of the above complex conditions, the supporting background of a typical roadway No.202 ...
