Research on the Distribution Law of Three Zones of Spontaneous Combustion in the Goaf of the 8123 Fully Mechanized Caving Face of Xinjing Mine
In response to the problems of thick coal seams,severe air leakage in adjacent layers,and complex spontaneous combustion of residual coal in the 8123 fully mechanized caving face of Xinjing Mine,bundle tube monitoring was adopted to clarify the distribution range of the"three zones"of spontaneous combustion in goaf,and the minimum advancing speed of the working face was calculated to ensure safe mining.This can provide reference for the prevention and control of spontaneous combustion of residual coal in goaf areas with similar geological conditions in the mine.
