Deformation Simulation of surrounding rock at faulted zone during roadway drivage Yue-ming Qi 1,a , Xiao-er Zhao 1,b，, Hai-bo Bai 1,c , Yang Jiao 1,d 1State Key Laboratory for Geomechanics&Underground Engineering, China University of Mining and Technology, Xuzhou 221008, China aym_qi@126.com, b zxe7866321@126.com, chbbai@126.com, djy19880103@126.com Keywords: transportation roadway, deformation of surrounding rock , faulted zone, COMSOL Multiphysics Abstract：Sometimes transportation roadways needed to go through the water-conducted normal fault with high dip and big fault throw in order to ensure the mining continuance, the two key factors were fault water and deformation of surrounding rock which influenced the digging safety and stabilization of roadways.
Li-tian Bo et al had observed the roadway deformation of mudstone roof and studied the surrounding rock fracture evolution[10].
