Abstract: In order to solve the Tashan mine 8104 working face in fault gas high pumping Lane inclined section of the wear layer of roadway, in neighboring 8103 working face mining in complex structure area excavated during the difficult to maintain and serious deformation. On the basis of studying the failure mechanism of the roadway, the paper puts forward the scheme of the bolt grouting support. Through theoretical research and practical application, it is indicated that the anchoring grouting supporting scheme not only keeps the stability of the tunnel in the layer, but also obtains the remarkable safety and economic benefits.
