Abstract 3200 working face in Malong Mine planned to withdraw support 20 m from materials roadway, in order to improve the coal resource recovery rate, mining succession and the economic benefit of mine, the materials roadway was taken as the withdraw roadway. The support parameters were optimized based on the geological condition, support theory. The material surrounding rock was reinforced, the deformation data of surrounding rock after reinforcement showed that the reinforcement plan enable to control the deformation of surrounding rock and make sure the safe and efficient support withdraw, with good economic benefit.
