The main controlling factors of coal seam injection heat enhanced extraction technology

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract In order to improve the gas extraction rate in low permeability coal seam, the coal injection thermal theory was proposed. Coal seam heat injection technology is still at the stage of theoretical and laboratory research. Thermal coal injection process is a very complex multi-physics coupling problem, involving factors such as ...
