摘　　要：针对大社矿921103工作面回采过程中受地质构造、工作面超前集中应力等因素影响,导致工作面煤壁片帮塌落、局部顶板发生漏冒的现象,对工作面煤壁进行了注浆加固。前期均采取了工作面煤壁短壁注浆加固方案,注浆材料选用化学浆,但因工作面破碎段范围广、片帮深度大及化学浆注浆量有限,工作面短壁注浆未能达到对煤壁加固的效果。根据此情况,研究在工作面运料巷施工长距离钻孔,对工作面煤壁提前进行注浆加固超前治理,配合工作面局部破碎点短壁注浆,保证工作面煤壁加固效果,为工作面安全回采打下良好基础。In view of the phenomena of coal wall collapse and local roof leakage caused by geological structure and pre-concentrated stress of working face in No.921103 Face of Dashe Mine,the coal wall of working face was reinforced by grouting.In the early stage,the short wall grouting reinforcement scheme of the coal wall of the working face was adopted,and the grouting material was chemical slurry.However,due to the wide range of the crushing section of the working face,the depth of the large collapse range and the limited amount of chemical slurry grouting,the effect of short wall grouting on the working face could not achieve the effect of strengthening the coal wall.According to this situation,the construction of long distance drilling in the material transport lane of the working face to carry out grouting reinforcement and advance treatment of the coal wall of the working face in advance was studied,and cooperated with the grouting of the short wall of the local broken point of the working face to ensure the strengthening effect of the coal wall of the working face,realized the transformation from passive treatment to active advance prevention,and laid a good foundation for the safe mining of the working face.
