Abstract: In view of the problem that the underground pressure of the mining roadway in the lower part of the goaf by Wongawilli mining method appears intensely, taking Shigatai of Shendong Mining Area as the engineering background, this paper studies the laws of the underground pressure of the working face and the corresponding measures through the goaf by means of on-site investigation and monitoring, and verifies the engineering practice. The results show that when the working face advances 27 m, the ground pressure appears intense, and the coal wall appears the phenomenon of rib spalling and blasting. The first weighting step of the working face is 35 m, the periodic weighting step is 11.3 m, and the weighting step of the goaf is 13.6 m. When the working face enters the goaf of Wongawilli mining, the first weighting of the working face will lead to severe ground pressure and serious damage of the roadway. The methods of increasing mining height, adjusting working face inclination and strengthening production organization to pass through stress concentration area at one time are proposed. Engineering practice shows that this method can effectively alleviate the safety of strata pressure in working face and ensure the safe mining of working face.
