Abstract: Niaoshan Coal Mine introduced fully mechanized top coal caving and gob-side entry retaining technology during the mining process of 11031 working face. Mineral pressure of working face and deformation law of surrounding rock of roadway. Theoretical analysis and calculation, mine pressure monitoring analysis and research show that the optimal depth of pre-split slit is 14.0 m, and the slit angle is 20°. During the construction period, the moving amount of roof and floor was finally stabilized at 79 mm, and the moving amount of the two sides was stable at 87 mm. The deformation of the roadway was small, and the average pressure of the 110 method area (the side of the cutting seam) was lower than that of the 121 method area (the side away from the cutting seam). 25.1%, and achieved good results, filling the gap of gob-side entry retention technology for roof cutting and pressure relief in Niaoshan Coal Mine.
