The mechanism of permeability enhancement of coal seams by hydraulic fracturing based on the characterization of coal physical properties

Abstract To further understand the mechanism of pressure relief and permeability enhancement in coal seams through hydraulic punching, this study employs microscopic testing methods such as porosity testing, spectral analysis, and image scanning, combined with simulation techniques, to analyze the i...
