Application of Cutting Roof Roadway Rock Burst Prevention Technology of Thin Coal Seam Group Mining in Taoshan Mine

Feng Jun-jie

Abstract

In this paper,cutting roof roadway prevention technology is previously tunneling a series of roadways between upper crossheading and gas high pumping lane to weaken the roof.When the working face advance to the cutting roof roadway region,the roof would be broken to avoid large roof hanging,the impact of risk is reduced.Taking Taoshan Mine as research object,the rock burst hazard is decreased with the cutting roof roadway,and notable effect has been made,which proves the feasibility of cutting roof roadway rock burst prevention technology in thin coal seam group mining.
