摘　　要：针对杨家村煤矿“埋深浅、采高大、工作面长”的工程特点,现使用的束管监测系统,样气从采样点需要经过长距离的束管负压运输才能到达井上。长距离束管管路难维护,一旦发生漏气,检测的结果就不可靠。长距离取气需要较长的时间,一次循环周期长,连续检测的分析频度不足。且负压抽送气样易受污染,分析监测数据不准,采样能力小,日常维护成本高。系统进行升级改造,结合微型气相色谱检测技术、束管正压输气技术、数据网络传输技术等高新技术,将微型气相色谱分析技术应用到矿井安全监测领域,将监测设备布置在井下,采用正压输气方式,利用多组分气体分析仪分析气体浓度,通过网络与计算机连接传输数据;针对电脑、手机等不同的使用场景,设计专门的使用软件,方便用户随时随地操作。本次升级改造将色谱仪布置于煤矿井下应用,能够快速准确分析火灾数据,在线监控井下灾情变化趋势,自动甄别束管漏气和破损情况,自动诊断故障点等,每年可节约系统运行维护费用15万元以上。In view of the engineering features of Yangjiacun Coal Mine's"shallow burial depth,high mining height,and long working face",the current bundled tube monitoring system uses an air pump to pump the gas samples from the monitoring point to the ground through the bundled tube,the sample gas needs to be transported by negative pressure in a long-distance bundle tube from the sampling point to reach the well.Long-distance bundled pipes are difficult to maintain,and once air leakage occurs,the detection results will be unreliable.It takes a long time to take gas from a long distance,a cycle is long,and the analysis fre‐quency of continuous detection was insufficient.The actual situation of negative pressure pumping gas samples was easily con‐taminated,the analysis and monitoring data were inaccurate,the sampling capacity was small,and the daily maintenance cost was high.The system was upgraded and transformed,combining the micro gas chromatography detection technology,the beam tube positive pressure gas transmission technology,and the data network transmission technology and other high-tech,the micro gas chromatography analysis technology was applied to the field of mine safety monitoring.The monitoring equipment was arranged underground,the positive pressure gas transmission method was used,the gas concentration was analyzed by a multi-component gas analyzer,and the transmission Data was connected to the computer through the network.For different usage scenarios such as computers and mobile phones,special software was designed to facilitate users to operate anytime,anywhere.In this upgrade,the chromatograph was installed in the underground coal mine,which can quickly and accurately analyze the fire data,monitor the trend of the underground disaster situation online,automatically identify the leakage and damage of the bundle pipe,and automati‐cally diagnose the fault point,which can save more than 150000 yuan in the system operation and maintenance every year.
