Thermo‐Mechanical Analysis of Crack Propagation Process in Heterogeneous Brittle Coal and Its Effects on the UCG Cavity Growth Rate

Thermo‐Mechanical Analysis of Crack Propagation Process in Heterogeneous Brittle Coal and Its Effects on the UCG Cavity Growth Rate

ABSTRACT The mechanism of cavity growth in a UCG process is mainly dependent on the presence of fractures and microcracks in the coal seam. In this study, the rate of cavity growth and the crack propagation mechanism in brittle coal samples under high thermal conditions are investigated using a two‐...
