Data for: Evaluation criterion and index for the efficiency of thermal stimulation to dual coal permeability

Heat injection into coal seams can stimulate coalbed methane reservoirs to enhance the recovery of
coalbed methane. However, the effects of temperature change on coal permeability are still unclear.

向煤层注入热能可激活煤层气（coalbed methane）储层，进而提升煤层气采收率。然而，温度变化对煤体渗透率的影响仍不明确。
