Numerical study of coal reservoir and borehole parameters evaluation considering temperature and multi-borehole superposition effects

Abstract To reveal the effects of temperature on the effective extraction radius and coal reservoir parameters during gas extraction in bedding boreholes, a hydraulic-mechanical coupling model (HM) and a thermal–hydraulic-mechanical coupling model (THM) for borehole gas extraction are established. T...
