Abstract:
Aiming at the deformation condition of shaft station in Liuzhuang coal mine in SDIC Xinji Group, on the basis of analyzing roadway failure reasons and control technologies, the techniques including preventing explosive, inner anchor outer support, inverted arch, grouting are applied in shaft station waiting chamber, which effectively prevents deformation and displacement of roadway, keeps stability of surrounding rock of roadway and solves the safety problems about up-down shaft in Liuzhuang Coal Mine Western area.
