综合物探在煤矿井下火源探测中的尝试

Discussion on the comprehensive geophysical exploration used in the detection of coal mine fire source

在煤矿开采过程中,由于种种原因引起煤层燃烧的事件时有发生。煤层的燃烧会给煤矿带来巨大的损失,在高瓦斯矿井还会酿成大事故。为了探测煤矿井下火源,利用地面同位素测氡法、地面高精度磁法、自然电位法,井下热红外测温法等手段,通过地面、井下相结合的多种方法综合解释,最终确定了火源中心位置及范围,总结了综合物探不同物探方法在火源探测中的优缺点。

In coal nfining process, coal seam combustion events happen frequently due to various reasons. The coal seam combustion will bring huge losses to coal nfines, and accidents will also happen in high gas nfines. In order to detect underground fire source of coal mine, using the comprehensive geophysical exploration method of ground radon measurement method, ground high precision magnetic method, self-potential method and underground thermal infrared thermonletry meth od,through comprehensive interpretation combined ground with underground, the center position and scope of fire source was ultimately determined. Finally, the paper summarized the advantages and disadvantages of comprehensive geophysical prospeering method in the detection of fire source.
