Coal Damage Impact on Gas Drainage Permeability by Johan Pranata is a document available to read on EtoBox.
1. Coal permeability is an important parameter that affects gas drainage from underground coal mines. However, previous studies have not fully considered how coal damage impacts permeability. 2. This study improves the Cui-Bustin permeability model to account for the effects of coal damage on permeability. A numerical simulation is developed using the improved model to analyze permeability distribution around roadways. 3. Results show tensile failure mainly occurs on the upper and lower sides of roadways
