Hydraulic fracturing technology, as an important means of active control of mine pressure and treatment of rock (dynamic) mechanical problems, has been successfully applied to all kinds of coal mine dynamic pressure influence roadway cutting top pressure relief, hard hanging roof caving, rock burst (rock burst) prevention and control, low permeability coal seam permeability and so on. Dr. Liu Jiangwei completed the theoryThe closed-loop development mode of → technology → equipment research and development → engineering application has initially formed the application system of hydraulic fracturing in mines. The research results have effectively solved the technical problems caused by hard sandstone and hard limestone. At present, it has been popularized and applied in 15 mines such as Datong Coal Mine Group, Xishan Coal and Electricity Group, and Huaibei Mining Group Co., Ltd.
