摘　　要：以国家能源集团乌海能源有限责任公司公乌素煤矿南采区为研究对象,结合磁法与测氡法,在已知火区试验工作的基础上,对南采区井筒周围及露头区指定区域进行了双重探查,利用火区磁性异常变化特征及氡气浓度差异原理,经过采集数据并进行资料分析对比,解释划定了南采区井筒周边及露头区正常区、增温燃烧区、降温燃烧区或熄灭区范围,为下一步火区治理工作提供了基础依据,对有针对性地实施灭火工程具有重要的指导意义。In this paper,the south mining area of CHN Energy Wuhai Energy Wusu Coal Mine is the research object.In combination with magnetic prospecting and radon measurement,both the area around the shaft of the south mining area and the designated area of the outcrop area are detected on the basis of the known fire area test.According to the characteristics of magnetic anomaly change in fire areas and the principle of radon concentration difference,after collection,analysis and comparison of the data,the scopes of normal area,heating burning area,cooling burning area or extinguishing area around the shaft and outcrop area in the south mining area have been defined to provide a basis for the next fire control,essential for the targeted implementation of fire extinguishing engineering.
