摘要
煤田火灾严重威胁火区生态环境和国家能源安全,我国是遭受煤火灾害最为严重的国家,因此煤火的治理十分迫切,煤火的准确探测是有效治理的前提。分别介绍了基于煤火热场特征的遥感与地表测温法,基于煤火地磁场特征的磁法,基于煤火电场特征的直流电法、电磁法和自然电位法以及基于煤火地球化学场特征的气体测定法、测氡法,并对各探测方法的国内外研究现状和优缺点进行了总结,最后指出基于火区电、磁场异常的电法和磁法是今后煤田火灾探测的重点研究方向。
Coalfield fire severely threatens the ecological environment and national energy safety, and China suffers from this disaster seriously. Therefore, the research and management of coal fire is imminent. Accurate detection of the coal fire is the premise of effec- tive governance. This paper respectively introduced the remote sensing and surface temperature measurement method based on the ther- mal characteristics of coal fire, the magnetic method based on the geomagnetic characteristics of coal fire, the direct current method, e- lectromagnetic method and self - potential method based on the electric field characteristics of coal fire, the gas measurement method and ground radon exploration method based on the geochemical characteristics of coal fire. Then the research situation and the advanta- ges and disadvantages of each method were summarized. Finally, it was pointed out that the electrical and magnetic method based on the electrical and geomagnetic characteristics of coal fire were the key research directions of coal fire detection.
