摘　　要：精准测定火区范围对于治理新疆煤田火区具有重要意义。本文采用无人机作为航空瞬变电磁设备载体,获取并处理了奇台将军庙煤田火区的磁测数据,根据火区和正常围岩的磁化强度值存在明显磁异常特征,定性和定量解释出煤层自燃火区的范围及深度。与其他物探方法结果相互验证,确定了着火煤层、火区边界和面积。实践研究表明,所采取的航空瞬变电磁勘查方案具有较高的准确性和可靠性,为“十四五”期间新疆煤田火区的精准勘查和治理提供了良好的借鉴。Accurate measurement of the fire zone extent is of great practical significance for the management of Xinjiang coalfield fire zone.In this paper,unmanned aerial vehicles is used as the carrier of airborne transient electromagnetic equipment to acquire and process the magnetic survey data of the fire zone in the Qitai Jiangjunmiao Coalfield,and the scope and depth of the spontaneous combustion fire zone of the coal seam are qualitatively and quantitatively interpreted according to the obvious magnetic anomaly characteristics of the magnetization intensity values of the fire zone and the normal surrounding rocks.The results were verified with those of other geophysical exploration methods,and the boundaries and areas of coal seams and fire zones on fire were determined.The practical study shows that the airborne transient electromagnetic survey program has high accuracy and reliability,and provides a good reference for the accurate survey and management of fire zones in Xinjiang coalfield during the"Fourteenth Five-Year Plan"period.
