Study on Safety Guarantee System of Hydraulic Fracturing in Underground Coal Mine

In order to improve the safety of underground hydraulic fracturing technology, we take the system engineering principle as the instruction, and construct "five-in-one" safeguard system which takes "division of dangerous levels, regional directional pressure relief, construction organization and management, multiple safety comprehensive protection and emergency rescue" as the main content, to ensure the safe and smooth progress of the hydraulic fracturing drive.
