Abstract When the single-wing mining of the mine is carried out, the working face is moved by the adjacent face. The roadway on the goaf side is affected by the mining depth, mining height, reserved coal pillar and the mining action of the upper working face. The strata pressure is strong and the surrounding rock is obviously deteriorated. Taking 15101 fully mechanized working face in Jingfu Coal Mine as an example, in view of this situation, measures such as optimizing and strengthening support, advancing along the trough, and strengthening organization and management were adopted to ensure the normal advancement of the working face. Through the application of the above technical means, the surrounding rock deterioration phenomenon of the goaf side roadway and the field operation environment are significantly improved, the material consumption is reduced, and the safe and stable production of the 15101 fully mechanized mining face is guaranteed.
