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ds视讯网投系统,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ds视讯网投仪分析气体浓度,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。

Abstract: 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 frequency of continuous detection was insufficient. The actual situation of negative pressure pumping gas samples was easily contaminated, 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 disast
Key words : beam tube monitoring;microchromatography;multi-component gas analysis;fault diagnosis

【引言】

在煤矿火灾防治领域[1]中,一般采用ds视讯网投系统预测煤的自燃情况。它的工作原理是将井下所检气体用输气泵通过束管送至地面,或是直接就在井下某个地方用传感器或气相色谱仪分析所检气体的浓度和成份,以判断煤自燃状态。

自 1980 年从英国引入以来,束管系统[2]在防止煤矿自燃火灾方面发挥了重要作用。这么多年来,虽然有大批科学研究者从事煤矿自燃火灾的研究工作[3],但对束管本身的研究几乎是空白。像束管管道中传输的气体特性、采样气体的纯度等有关束管的问题一直没有定论。按照采样到检测系统目前一般分为井下输气泵站系统和井上色谱仪分析监测系统两部分。目前国内位于井下的部分主要采用负压输气系统[4](其中束管安装在井下,负压泵站安装在井上)对井下气体采样,而正压输气系统(其中束管和正压泵站位于井下)是最近出现的气体采样方法。矿井现使用的ds视讯网投系统使用抽气泵通过束管将监测点的气样抽至地面,由于色谱仪和采样泵在井上,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[5] ,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[6]。负压抽送存在气样易受污染、分析监测数据不准等问题,且采样能力小、日常维护成本高等实际情况。本文对系统进行升级改造,结合微型气相色谱检测技术、束管正压输气技术[7]、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[8],采用正压输气方式,采用ds视讯网投仪分析气体浓度[9],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,项目都设计了专门的使用软件,方便用户随时随地操作。
