Abstract: In order to effectively control the destruction of theⅡ 46 rail upper yard, the winder chamber and the surrounding rock of roadway in Liuqiao No.1 Mine caused by the mining, the factors for the destruction of surrounding rocks are firstly analyzed from aspects of engineering layout, support structure and surrounding rock strength.On the basis of the existing project, the corresponding reinforcement parameters and construction technology are proposed, and the check computation for the resistance 9.10 MPa of the grouting circle and the fractured rock grouting radius of 2.24 m are made.The observation data after and before the surrounding rock deformation show: the average approaching speed of two sides before anchor-grouting is 1.5mm/d, and the roof and floor approaching rate is 4.0 mm/d; the average approaching rate is 0.75 mm/d and the roof and floor approaching rate is 2.0 mm/d after reinforcement for 7~28 d.From the reinforcing effect view, the reinforcement program can effectively control the surrounding rock deformation caused by mining.
