Research on Distribution Characteristics of Spontaneous Combustion"Three Zones"in Goaf of Liyazhuang Coal Mine Working Face
In response to the problem of spontaneous combustion of coal seams in the goaf of the 2-801 fully mechanized mining face of Liyazhuang Coal Mine,Huozhou Coal Power Group Co.,Ltd.,the spontaneous combustion"three zones"in the goaf were studied using on-site measurement methods.By analyzing test data,it was determined that the width of the scattered heat zone in the natural ignition"three zones"of the goaf of the 2-801 working face is 0～21.2 meters,the width of the oxidation zone is 21.2～83.5 meters,and the area above 85.5 meters is the suffocation zone.The research results provide technical support for the prevention and control of coal seam spontaneous combustion in goaf.
