專利名稱：一種煤礦井下采空區(qū)的瓦斯分布測(cè)量方法
技術(shù)領(lǐng)域：
本發(fā)明涉及一種煤礦井下采空區(qū)的瓦斯分布測(cè)量方法，屬于煤礦安全有關(guān)采空區(qū)瓦斯分布測(cè)量的技術(shù)領(lǐng)域。
背景技術(shù)：
在煤礦井下采煤作業(yè)中，將會(huì)產(chǎn)生瓦斯氣體，瓦斯事故是煤礦的突出災(zāi)害，瓦斯事故和死亡人數(shù)占到事故總數(shù)的50%以上，如何預(yù)防、消除瓦斯事故是一個(gè)非常重要的研究課題。在采煤作業(yè)中，煤層中的瓦斯氣體就會(huì)釋放出來(lái)，一部分瓦斯氣體隨著煤炭運(yùn)輸、 井下通風(fēng)而排出，一部分瓦斯氣體遺留在采空區(qū)，并在采空區(qū)進(jìn)行儲(chǔ)存集聚，使瓦斯的濃度增大，造成很大的安全隱患，因此，如何掌握、測(cè)量采空區(qū)的瓦斯分布是十分重要的，可為制定采空區(qū)瓦斯治理措施提供依據(jù)。由于井下采空區(qū)人員無(wú)法達(dá)到，對(duì)煤礦井下采空區(qū)的瓦斯分布測(cè)量顯得十分困難，目前測(cè)量方法較少，現(xiàn)有的方法測(cè)量準(zhǔn)確性差，無(wú)法掌握真實(shí)的瓦斯分布規(guī)律，給治理采空區(qū)瓦斯帶來(lái)了困難。

發(fā)明內(nèi)容
發(fā)明目的本發(fā)明的目的是針對(duì)背景技術(shù)的狀況，對(duì)煤礦井下采空區(qū)瓦斯的分布測(cè)量用采用束管抽氣、傳感器采集信息、以及采用流體力學(xué)原理及計(jì)算機(jī)軟件進(jìn)行數(shù)據(jù)模擬，依靠微計(jì)算機(jī)程序完成采空區(qū)瓦斯分布測(cè)量，使測(cè)量的瓦斯?jié)舛戎禍?zhǔn)確、可靠，給瓦斯治理提供科學(xué)依據(jù)。技術(shù)方案本發(fā)明測(cè)量方法如下瓦斯氣體測(cè)量是在煤礦井下采空區(qū)直接取樣進(jìn)行的，是在瓦斯分析儀上用微計(jì)算機(jī)處理器進(jìn)行信息分析、程序化完成的；(1)測(cè)量準(zhǔn)備①設(shè)置測(cè)量工作艙測(cè)量工作艙為方艙式，恒定溫度為22°C 士2°C，相對(duì)濕度彡20%，為潔凈、陰涼、干燥環(huán)境；方艙內(nèi)置放瓦斯分析儀、數(shù)據(jù)打印機(jī)、儲(chǔ)氣罐、束管采樣裝置；②在工作面采空區(qū)設(shè)置采樣探頭，在工作面進(jìn)回風(fēng)巷道內(nèi)設(shè)置采樣束管，并把它們聯(lián)通起來(lái)；③在工作面內(nèi)設(shè)置甲烷傳感器，一氧化碳傳感器，并通過(guò)傳感器信號(hào)線與瓦斯分析儀聯(lián)接；(2)采取采空區(qū)瓦斯氣體
開啟采氣泵，通過(guò)采樣探頭和采樣束管，將瓦斯氣體收集于瓦斯儲(chǔ)氣罐內(nèi)；(3)采集甲烷氣體信息將甲烷傳感器置于工作面內(nèi)，通過(guò)傳感器信號(hào)線把采集到的甲烷氣體信息傳輸?shù)酵咚狗治鰞x；(4)采集一氧化碳?xì)怏w信息將一氧化碳傳感器置于工作面內(nèi)，通過(guò)傳感器信號(hào)線把采集到的一氧化碳?xì)怏w信息傳輸?shù)酵咚狗治鰞x；(5)在采空區(qū)釋放六氟化硫示蹤氣體，并收集混合后的瓦斯氣體+六氟化硫氣體， 然后輸入儲(chǔ)氣罐內(nèi)；(6)瓦斯分析儀測(cè)量①瓦斯分析儀接受甲烷傳感器信息，經(jīng)微計(jì)算機(jī)處理器進(jìn)行程序運(yùn)算，得出甲烷氣體值，并指令打印機(jī)打印出相關(guān)數(shù)據(jù)；②瓦斯分析儀接受一氧化碳傳感器信息，經(jīng)微計(jì)算機(jī)處理器進(jìn)行程序運(yùn)算，得出一氧化碳?xì)怏w值，并指令打印機(jī)打印出相關(guān)數(shù)據(jù)；③將瓦斯氣體儲(chǔ)氣罐內(nèi)氣體輸入瓦斯分析儀中，由微計(jì)算機(jī)處理器進(jìn)行瓦斯氣體成分、濃度、量值分析，然后指令打印機(jī)打印出瓦斯氣體信息；④將采集的瓦斯氣體+六氟化硫氣體混合氣體輸入瓦斯分析儀中，由微計(jì)算機(jī)處理器進(jìn)行對(duì)比分析，并指令打印機(jī)打印出對(duì)比分析信息；⑤瓦斯分析儀測(cè)量工作面甲烷氣體、一氧化碳?xì)怏w、采空區(qū)瓦斯氣體、采空區(qū)瓦斯氣體+六氟化硫混合氣體，是由分析儀的微計(jì)算機(jī)處理器程序完成的，測(cè)量程序使用VC語(yǔ)言平臺(tái)，程序如下
