我国煤炭资源丰富，煤炭的产量和消费均居世界前列。煤炭在国内一次性能源消费中占主导地位。由于历史原因，在地层中形成火烧区和采空区。火烧区的形成是由于煤层物化条件的改变发生自燃，而煤炭在开采的过程中地下会形成采空区，这已经成为了一种典型的地质灾害，其探测仍属于难题。 本文分析研究了瞬变电磁和磁法的工作原理、选用瞬变电磁对采空区进行探测，采用磁法对火烧区边界进行圈定，对研究区的地质概况和地球物理特征进行了分析，以此为基础制定了研究方法，如施工方法、测点布设等，对采集到的数据进行了全面系统的处理和解释，绘制了对应的剖面图和平面图。通过磁法和瞬变电磁的成果图，再结合研究区地质地形、钻孔及实地调查情况，对研究区火烧区进行了圈定，对采空积水区进行了综合推断解释。经验证认为对火烧区以及采空积水区进行瞬变电磁及磁法综合物探，效果良好。

China is rich in coal resources, coal production and consumption are among the forefront of the world .Coal occupies a dominant position in the domestic disposable energy consumption.Due to the historical reasons, the formation of coal fire area and mined out area is inevitable.The formation of coal fire area is due to the change of physical and chemical conditions in the coal bed.And in the process of coal mining underground, there will form mined out area,which has becomes a typical geological disaster, but its detection is still a problem. In this paper,the working principle of magnetic and electromagnetic transients are analyzed;elect the electromagnetic transient and magnetic detecting the goaf and burning area.Analyzing the geology and geophysical characteristics of the study area.So that we making the research methods,including the construction method and monitoring point arrangement etc.Then interpreting the data capture completely,after that drawing the cross-sectional map and plane graph one by one.Finally,combined the map making a delineation of burning area and conducting a comprehensive water inference and interpretation.The study verified to be more effective and hows that mined area conducted a transient electromagnetic and magnetic methods.
