地下煤火分布及探测技术现状研究

Research on the Status of Underground Coal Fire Distribution and Development of the Detection Technology

基于对国内外地下煤火形势的研究,分析了国内外煤火的分布现状及原因,探讨了不同煤火探测技术的优缺点及适用范围。结果表明:我国煤火主要分布在北纬35°~45°地区,全球煤火重灾区主要位于在北纬25°~55°地区之间。该现象主要与煤质变质程度、开采强度以及气候条件相关。经过对现有技术的深入调查与分析,得出煤火探测技术设备在精度和抗干扰方面需要加强。因此,了解煤火的分布及探测技术,对煤火的研究防治具有重要意义。

Based on the study of underground coal fire situation,the distribution status and causes of coal fire are analyzed,and the advantages and disadvantages of different coal fire detection technologies and their scope of application are discussed.The results show that the coal fires in China are mainly distributed in the 35°-45°north latitude,and the global coal fire disaster area is mainly located between 25°-55°north latitude.This phenomenon is mainly related to the degree of coal quality deterioration,mining intensity and climatic conditions.After in-depth investigation and analysis of the existing technology,it is concluded that the coal fire detection technology equipment needs to be strengthened in terms of accuracy and anti-interference.Therefore,understanding the distribution and detection technology of coal fire is of great significance to the research and prevention of coal fire.
