Study on mining technology of overlying goaf and empty roadway with shallow buried fully mechanized mining face

Taking the 12424 fully mechanized mining face of Bulianta Coal Mine as an example, this paper investigates the mining technology of shallow buried fully mechanized mining faces passing through overlying goaf and empty roadway. Specifically, through the observation of mining pressure on the fully mechanized mining face, the production situation of entering and exiting the overlying goaf on the fully mechanized mining face, and the mining situation under special conditions such as passing through the overlying goaf and over height sections of the inclined groove on the fully mechanized mining face, a detailed analysis is conducted on the initial pressure, cyclic pressure, and pressure under special geological conditions, which has guiding significance for similar mining on fully mechanized mining faces.
