Abstract: To reduce the difficult of rock roadway drivage and increase driving speed,this paper analyzed the stress distribution of the roadway working face of Liliangdian Mine west 4 main return way by numerical simulation software FLAC^3D.And the analysis results were applied to field practice.The results show that rock masses are in the relative equilibrium ground stress field under the effect of the self-weight stress field and the other stress fields before the deep engineering excavation.Because of the excavation,the equilibrium state of rock initial stress is broken in underground engineering construction period.And it causes a series of deformation and failure phenomena due to stress release,the stress redistribution nearby excavation area,and the formation of 0~2.0m stress decreasing zone and 2.0~18.5m stress increasing zone in the front of the working face,including 2.5~3.8m high stress zone.It guided drilling and blasting method that the field blasting driving drilling tried to avoid high stress zone,improved efficiency of borehole,accelerated 30% of roadway driving speed,reduced unnecessary casualties and economic losses with obvious economic benefit.
