Research on re-fracturing mechanism and cavity structure evolution characteristics of broken rock mass in goaf of closed mine
Due to the “Dual Carbon” policy impact, geothermal extraction technology in closed mines has garnered increasing attention. The efficiency of extracting thermal fluid within the closed mine goaf is related to the permeability characteristics, with the broken rock mass porosity structure playing a ke...
