Study on technique of the reinforcement of grouting and bolting in complex area in rock-roadway of Xinsan mine

Problems such as severe deformation of surrounding rock and water pouring in area with geological structure,cracking surrounding rock or large quantities of water in roadway of Xinsan Mine greatly restrict high efficiency of production.Reinforcing those areas by grouting and bolting not only ensures producing but solves problems caused by repairing them time after time.This paper also analyses the mechanism and effect of grouting and bolting reinforcement,which shows that this technique can make technical,economical and social effects.
