Application of Bolting and Shotcreting Combined Support Technology in Xiangshan Coal Mine

In order to increase tunelling speed and save timbering cost of East Wing Second Team's -250 meters special wind return roadway, the paper makes a research on high speed-tunelling under the conditions of large inclination and thick coal seam, and proposes the bolting and shotcreting combined support way. Through comparing with original support way and bolting and shotcreting combined support way on ground pressure monitor and technical cost, the new way offers unclear ground pressure and saves about 10% support cost, it also guarantees the East Wing Mining Area to product on schedule, and tunnel quality and service life can meet the design requirement.
