摘　　要：为有效防控煤矿井下带式输送机火灾事故,保障煤矿工作人员的生命财产安全,系统分析矿井带式输送机火灾的起火原因、燃烧特性、烟流特性、监测预警技术及防治措施,并基于当前研究现状提出展望。结果表明:引发带式输送机火灾的主要原因是摩擦温升、电气设备故障及明火;研究带式输送机火灾燃烧和烟流特性采用的巷道火灾模型及数值模拟相关参数具有一定局限性,需综合考虑运输巷道实际工况及环境等参数;国内虽有针对带式输送机火灾的监测预警系统,但其尚有不足,需引入5G、大数据及人工智能等新兴技术予以完善,并结合硬件探测及人员管理等方面,健全煤矿带式输送机火灾防治体系,进而全面推动煤矿安全智能化建设。To effectively prevent and control coal mine underground belt conveyor fire accidents and ensure the safety of lives and property of coal mine workers,the fire causes,combustion characteristics,smoke flow characteristics,monitoring and early warning technologies,and prevention measures of mine belt conveyor fires were systematically analyzed.Then,further prospects were proposed based on the current research status.The results showed that the main causes of belt conveyor fire were friction temperature rise,electrical equipment failure,and open flame.There were some limitations for the tunnel fire model and corresponding numerical simulation parameters used to study the fire combustion and smoke flow characteristics of belt conveyors,the actual working conditions and environmental parameters of the transportation tunnel should be comprehensively considered.Although there were monitoring and early warning systems for belt conveyor fires in China,they had some limitations.It was necessary to introduce emerging technologies such as 5G,big data,and artificial intelligence,and combine them with hardware detection and personnel management to improve the coal mine belt conveyor fire prevention and control system,and then comprehensively promote the construction of safety and intelligent in coal mine.
