Permeability of Broken Coal Around CBM Drainage Boreholes with the Compound Disaster of the Rockburst and Outburst

Coal seam gas drainage serves as an effective engineering measure to mitigate compound disasters of the rockburst and outburst in deep mining, and its efficacy is fundamentally governed by the permeability of coal around the gas drainage borehole. To systematically study the permeability law of brok...
