摘　　要：针对霍州煤电集团有限责任公司李雅庄煤矿2-801综采工作面采空区煤自燃问题,采用现场实测的方法对采空区自燃“三带”进行了研究。通过分析测试数据,确定2-801工作面采空区自然发火“三带”散热带的宽度为0~21.2m,氧化带宽度为21.2~83.5m,85.5m以上为窒息带。研究结果为采空区煤自燃防治提供了技术支持。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.
