Abstract：With the increase of mining intensity and depth,the method of simply transforming the floor water layer and the thin-bed limestone aquifer can not meet the requirements of reducing the water inrush coefficient,and the current more mature is to adopt the way of grouting reinforcement in the ground area,change the hydrogeological conditions of the rock mass,and transform the relative aquifer into a relative aquifer by using the ground grouting method through the ground directional drilling construction technology,which can realize the safe mining of the mine at the same time,but also protect the precious groundwater resources.
