摘要:

为精确判定地下隐蔽高温火区的位置和范围,针对现有隐蔽火源探测常用的技术手段(热红外探测法、电阻率法、气体探测法、测氡法及数理解算法等)的原理及应用概况,分析煤矿井下隐蔽火源探测技术的研究发展现状,对比各类探测技术手段优缺点。结果表明:现有的常规探测技术可一定程度上实现煤矿井下采空区隐蔽火源位置探测及圈定,但受实际环境因素影响较大,难以实现位置和煤自燃程度的精准判定。声学法测温技术是一种相对成熟有效的温度检测技术,已在大气、海洋、高炉测温等领域广泛应用。在学科交叉融合理念的推动下,结合煤矿采空区隐蔽火源探测需求,探索基于声学法的煤体温度场重构方法,将为采空区隐蔽火源的精准探测技术发展提供新的研究方向和研发思路。

Abstract:

In order to accurately identify the location and scope of underground hidden high-temperature fire areas, research and development status of the hidden fire source detection technology in coal mines were analyzed based on principles and application overview of current commonly used detection methods (such as thermal infrared detection method, resistivity method, gas detection method, radon measurement method and mathematical understanding algorithm, etc.) and advantages and disadvantages of these detection techniques were compared. The results show that although existing conventional detection methods may detect and delineate hidden fire locations in mined-out areas of coal mines, it is difficult to accurately determine the location and degree of coal spontaneous combustion due to severe impacts of actual environmental factors. Acoustic temperature measurement method, as a mature and effective technology, has been widely used in fields of atmosphere, ocean, and blast furnace temperature measurement. Driven by the concept of cross-discipline integration, and given the demand for hidden fire source detection in goaf, exploring reconstruction method of coal temperature field based on acoustic method will provide new perspectives for the development of precise hidden fire source detection technologies.

Key words: coal spontaneous combustion, hidden fire source, detection method, goaf, acoustic temperature measurement
