摘　　要：新疆煤田火区是我国乃至世界上最大的煤田火区,煤火不仅消耗掉大量煤炭资源,同时其燃烧后释放的有毒有害气体也对大气环境造成了严重污染,对国土资源也造成了严重的破坏,极大的影响了当地经济、社会与生态的发展。因此精准勘查火区范围对治理煤田火区具有重要意义。由于各个火区所处的煤田地质条件并不一致,且发火影响因素有差异,所以目前针对火区的勘查手段并没有统一的执行标准,同时通过单一的勘查手段并不能完全准确查明煤田火区的燃烧状况,而为了提高勘测精准程度就需要使用更多的勘查手段,这便使得勘查成本大幅提升。为了平衡好勘查精准程度与勘查成本,本次针对新疆吐哈煤田急倾斜煤层火区采用了综合勘查手段,通过实践研究表明,在控制成本的基础上,本次采用的综合勘查手段有很高的准确度和可靠性,为其他具有类似地质与开采技术条件的煤田火区精准勘查提供了良好的借鉴。Xinjiang coalfield fire area is the largest coalfield fire area in China and even the world,coal fire not only consumes a lot of coal resources,but also the toxic and harmful gases released after combustion also cause serious pollution to the atmospheric environment,cause serious damage to land resources,and greatly affect the local economic,social and ecological development.Therefore,an accurate investigation of the scope of the fire area is of great significance to the control of the coalfield fire area.Due to the inconsistent geological conditions of the coalfield where each fire area is located,and the influencing factors of ignition are different,there is no unified implementation standard for the exploration methods of the fire area,and the combustion status of the coalfield fire area cannot be completely accurately identified by a single exploration method,and more exploration methods are required to improve the accuracy of the survey,which greatly increases the cost of exploration.To balance the accuracy of exploration and the cost of exploration,the comprehensive exploration method was adopted for the sharply inclined coal seam fire area of Xinjiang Tuha coalfield,and the practical results showed that based on cost control,the comprehensive exploration method adopted this time has high accuracy and reliability,which provides a good reference for the accurate exploration of other coalfield fire areas with similar geological and mining technical conditions.
