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】

在煤礦火災(zāi)防治領(lǐng)域[1]中,,一般采用束管監(jiān)測系統(tǒng)預(yù)測煤的自燃情況,。它的工作原理是將井下所檢氣體用輸氣泵通過束管送至地面,或是直接就在井下某個地方用傳感器或氣相色譜儀分析所檢氣體的濃度和成份,,以判斷煤自燃狀態(tài),。

自 1980 年從英國引入以來,束管系統(tǒng)[2]在防止煤礦自燃火災(zāi)方面發(fā)揮了重要作用,。這么多年來,,雖然有大批科學(xué)研究者從事煤礦自燃火災(zāi)的研究工作[3],,但對束管本身的研究幾乎是空白。像束管管道中傳輸?shù)臍怏w特性,、采樣氣體的純度等有關(guān)束管的問題一直沒有定論,。按照采樣到檢測系統(tǒng)目前一般分為井下輸氣泵站系統(tǒng)和井上色譜儀分析監(jiān)測系統(tǒng)兩部分。目前國內(nèi)位于井下的部分主要采用負(fù)壓輸氣系統(tǒng)[4](其中束管安裝在井下,,負(fù)壓泵站安裝在井上)對井下氣體采樣,,而正壓輸氣系統(tǒng)(其中束管和正壓泵站位于井下)是最近出現(xiàn)的氣體采樣方法。礦井現(xiàn)使用的束管監(jiān)測系統(tǒng)使用抽氣泵通過束管將監(jiān)測點的氣樣抽至地面,,由于色譜儀和采樣泵在井上,,樣氣從采樣點需要經(jīng)過長距離的束管負(fù)壓運輸才能到達(dá)井上[5] ,長距離束管管路難維護,,一旦發(fā)生漏氣,檢測的結(jié)果就不可靠,。長距離取氣需要較長的時間,一次循環(huán)周期長,,連續(xù)檢測的分析頻度不足[6],。負(fù)壓抽送存在氣樣易受污染、分析監(jiān)測數(shù)據(jù)不準(zhǔn)等問題,,且采樣能力小,、日常維護成本高等實際情況。本文對系統(tǒng)進行升級改造,,結(jié)合微型氣相色譜檢測技術(shù),、束管正壓輸氣技術(shù)[7]、數(shù)據(jù)網(wǎng)絡(luò)傳輸技術(shù)等高新技術(shù),,將微型氣相色譜分析技術(shù)應(yīng)用到礦井安全監(jiān)測領(lǐng)域,,將監(jiān)測設(shè)備布置在井下[8],采用正壓輸氣方式,,采用多組分氣體分析儀分析氣體濃度[9],通過網(wǎng)絡(luò)與計算機連接傳輸數(shù)據(jù),;針對電腦,、手機等不同的使用場景,項目都設(shè)計了專門的使用軟件,,方便用戶隨時隨地操作,。
