“Three zones” rule of spontaneous combustion in goaf under overburden separation grout filling

Meikuang Anquan
Overburden separation grout filling (OSGF) technology compacts the fragmented rock mass in the goaf and changes the seepage characteristics and distribution of the “three zones” of spontaneous combustion in the goaf.
