Abstract: In order to ensure the safe recovery of the 58008-3 working face of Laohutai Coal Mine, the "four-in-one" comprehensive anti-shock measures were analyzed during the 58008-3 working face tunneling and mining. According to the geological conditions and lithological characteristics of the mine, the impact risk areas are divided, and the support methods of various areas are strengthened. During tunneling and mining, the drill cutting method, acoustic electricity monitoring method and mine pressure observation method are used to predict the impact risk. The high-pressure water injection, pressure relief drilling, "two excavation and one drill" or "two drills and one excavation" are adopted. During the construction period, strictly follow the requirements of the coal mine safety regulations. The results show that the drill cuttings method can effectively predict the impact risk of the working face, and the high pressure water injection can effectively achieve the purpose of pressure relief. In general, the "four-in-one" comprehensive anti-shock measures are safe and effective in production.
