煤田火灾探测与治理技术现状及发展趋势

Current Situation and Development Trend for Coalfield Fire Exploration and Governance Technology

为给我国煤田火灾的探测与治理提供决策参考,促进我国煤田火区防控高效快速发展,通过对煤田火灾探测和治理技术进展与应用现状研究,分别探讨了煤田火灾探测的钻探法、物探法、化探法和遥感法,煤田火灾治理的直接剥离技术、控制漏风技术、火区惰化技术和吸热降温及煤体阻化技术的特点与适用性,分析了我国煤田火灾探测存在精度差,不能实现火源精确定位,治理技术不能实现快速高效治理大面积煤田火灾的问题,指出基于红外遥感、磁法和电法的多元信息探测和高温大热容煤岩体的快速降温灭火技术是未来煤田火灾探测与治理领域的发展趋势。

In order to provide decision-making reference for the coalfield fire exploration and governance,and to promote the efficient and rapid development of coalfield fire prevention and control,the characteristics and applicability of drilling exploration method,geophysical exploration method,geochemical exploration method and remote sensing exploration method for coalfield fire exploration and direct stripped technology,air leakage control technology,fire area inerting technology,endothermic cooling and coal inhibition technology for coalfield fire governance were discussed separately through investigative progress and current situation of coalfield fire exploration and governance.The exploration precision is low at present so that accurate location of fire source cannot be realized.Governance technology cannot achieve rapid and efficient treatment of large area coalfield fire.The development trends of coalfield fire exploration and governance in the future are the multiple information exploration technology based on infrared remote sensing,magnetic method and electric method,and the rapid cooling and extinguishing technology of high temperature and large heat capacity coal rock mass.
