Investigation of the Evolution of Stratum Fracture during the Cavity Expansion of Underground Coal Gasification

The evolution of fracture zone controls the safety of underground coal gasification (UCG) in terms of gas emission and water leakage. In order to understand the fracture propagation in the confining rock of a UCG cavity with various influence factors, this paper implemented a set of numerical models...
