摘　　要：为解决传统采空区自燃预警信息发现与采取措施滞后,系统投入成本高,监控有效难,预防判识难等问题,研发采空区自燃预警信息就近自动采集检测装置,通过对采空区自燃发火标志性气体氧气、一氧化碳、二氧化碳、甲烷、乙炔、乙烯等进行检测,实现采空区气体成分浓度参数的一站式就近获取、融入安全监控系统全面监测,从而真正实现采空区自燃发火状态、隐患风险实时监控、超限报警信息主动推送、运行记录信息自主便捷查询,为指导煤矿评估安全风险、精准实施防火措施奠定基础。全面提升煤矿采空区监测监控能力和设备智能化、信息化水平。In order to solve the problems such as the delay in finding and taking measures for the precursor information of spontaneous combustion in the traditional goaf,the high cost of system investment,the difficulty in effective monitoring,and the difficulty in prevention and identification,nearby automatic collection and detection device for precursor information of spontaneous combustion ingoaf is developed.The device detects the symbolic gases of spontaneous combustion in goaf,such as O2,CO,CO2,CH4,C2H2,C2H4.The device has the function of one-stop nearby detection of the concentration parameters of the gas components in the goaf,and integrates the detection data into the safety monitoring system for comprehensive monitoring,so as to truly realize the real-time monitoring of the spontaneous combustion status and hidden danger risk in the goaf,the active push of the overrun alarm information,and the independent and convenient query of the operation record information.This has laid a foundation for guiding the coal mine to assess safety risks and accurately implement fire prevention measures,and comprehensively improved the monitoring and monitoring capability of the goaf and the level of equipment intelligence and information.
