Short summary
Petro-physical and geomechanical properties undergo a drastic change due to heat generated during underground coal gasification. The thermal anisotropy of the minerals result in the generation of thermal stresses which result in fracturing of the rock. The new fractures lead to the failure of overhead strata thereby causing subsidence. This paper aims to predict the thermo-geomechanical response of the strata during UCG using COMSOL Multiphysics.
