Abstract In order to determine the reasonable parameters for pre-pumping coal seam gas in a single low permeability protruding coal seam by implementing high-pressure hydraulic fracturing borehole, a site investigation was conducted and the gas flow rate and residual gas content of the fracturing borehole were measured. High-pressure hydraulic fracturing technique for low permeability single protruding coal seam can effectively improve the drainage effect.
