分布式激光火情监控系统在寸草塔二矿的应用
|
摘要
为解决煤层自然发火监测存在的问题,寸草塔二矿建设了KJ428型煤矿安全监控系统。系统由煤矿井下火灾参数监测系统、基于以太网的数据传输高速通信系统和可视化、自动化和智能化的煤矿火灾监测预警系统组成。系统采用波长调制吸收光谱技术进行气体浓度检测,利用分布式光纤温度探测(DTS)技术进行易发火区域温度监测,使用分布式系统架构和设备部署方式,能够准确监测CH4、CO、C2H2、O2、C2H4和CO2共计6种气体浓度值和温度参数,降低了束管铺设长度和束管堵塞漏气故障概率。系统基于大数据智能分析技术,依据束管流量、压力、气体浓度变化,能够准确判断束管堵塞漏气故障和火情发展阶段。
The KJ428 mine safety monitoring system in Cuncaota No. 2 Coal Mine is composed of underground fire parameter monitoring system,data transmission high-speed communication system and mine fire monitoring and warning system. The system uses wavelength modulated absorption spectroscopy technology for gas concentration detection,distributed optical fiber temperature detection technology for temperature monitoring,which can accurately monitor six gas concentration values and temperature parameters,shorten the length of beam tube laying and reduce the failure probability of beam tube. Based on big data intelligent analysis technology,the system can accurately judge the beam tube fault and fire development stage according to the change of flow,pressure and gas concentration of beam tube.
