Abstract With the in-depth development of the coal industry, the high-quality resources in coal mines are decreasing. In order to release coal resources as much as possible, filling mining and residual coal re-mining have become an important technical means for coal enterprises to innovate technology and extend the service life of mines. At the same time, according to the continuous change of environmental protection policy, the disposal of solid waste such as coal gangue has gradually become a problem that major coal enterprises have to face. Based on the research of coal gangue and filling materials, the preparation and use method of coal gangue high water jet filling material was put forward, which solved the problem that the two corners of the underground comprehensive mechanized gangue filling coal mining technology could not be effectively filled, and the underground old roadway and empty roadway management cost was high, difficult, and it was easy to affect the coal quality after backfilling. At the same time, it met the needs of coal mine for gangue treatment.
