【摘要】：自然發(fā)火是煤炭著火一種客觀(guān)現(xiàn)象,也是煤礦自然災(zāi)害最為嚴(yán)重的一種。漏風(fēng)是造成采空區(qū)遺煤自燃的重要原因。小煤窯開(kāi)采方法簡(jiǎn)單,浪費(fèi)嚴(yán)重,開(kāi)采后遺留煤量大,一旦小煤窯采空區(qū)有充足供氧條件,時(shí)間一長(zhǎng)就會(huì)發(fā)生煤炭自燃著火。大礦在下部開(kāi)采后,采空區(qū)頂板垮落,由于層間距小,就會(huì)和小煤窯采空區(qū)或廢巷貫通,產(chǎn)生漏風(fēng),為其提供氧氣來(lái)源,使得遺煤氧化自燃升溫,最終著火,嚴(yán)重威脅著礦井安全生產(chǎn)。根據(jù)相關(guān)資料,廢棄小煤窯采空區(qū)遺煤自燃著火導(dǎo)致的礦井火災(zāi)占了90%以上。解決礦井的防滅火問(wèn)題,治理小煤窯自燃火災(zāi)就成了煤礦安全生產(chǎn)中的重點(diǎn)。本文針對(duì)西山煤電股份有限公司西曲煤礦上覆小煤窯采空區(qū)著火的特點(diǎn),提出了以火區(qū)信息檢測(cè)技術(shù)為主的綜合防滅火技術(shù)方案。 在對(duì)西曲礦29210工作面采空區(qū)上覆小煤窯火區(qū)信息檢測(cè)過(guò)程中,在理論研究方面應(yīng)用紅外熱像技術(shù)和漏風(fēng)檢測(cè)技術(shù)的相關(guān)理論進(jìn)行了研究。在實(shí)驗(yàn)分析方而,通過(guò)煤的交叉點(diǎn)溫度實(shí)驗(yàn),得出了西曲礦8煤和9煤的自燃臨界點(diǎn)和自燃傾向性。在現(xiàn)場(chǎng)探測(cè)應(yīng)用方面,通過(guò)對(duì)西曲礦29210工作面進(jìn)行的示蹤氣體檢測(cè),并對(duì)收集的氣體進(jìn)行的具體分析,檢測(cè)出可能存在的漏風(fēng)通道,勘察出一些可能引起煤炭自然發(fā)火的漏風(fēng)源。并通過(guò)紅外熱像技術(shù)觀(guān)測(cè)對(duì)內(nèi)部熱源溫度及表面溫度的監(jiān)測(cè)和對(duì)比分析,可以判斷隱蔽火源的存在,運(yùn)用反演公式計(jì)算得出的小煤窯距離,最后針對(duì)可能引起自燃發(fā)火的區(qū)域制訂了相應(yīng)措施,為西曲煤礦進(jìn)一步進(jìn)行綜合防滅火設(shè)計(jì)提供了可靠依據(jù)。
[Abstract]:Spontaneous combustion is not only an objective phenomenon of coal ignition, but also one of the most serious natural disasters in coal mines.Air leakage is an important cause of coal spontaneous combustion in goaf.The mining method of small coal kiln is simple, the waste is serious, and the amount of coal left behind is large after mining. Once there is sufficient oxygen supply condition in the goaf of small coal mine, coal spontaneous combustion will occur for a long time.After mining in the lower part of a large mine, the roof of the goaf collapses. Because of the small interval between the layers, it will pass through the goaf or the waste roadway of the small coal kiln, resulting in air leakage, which will provide a source of oxygen for the coal, which will cause the coal to be oxidized and self-ignited, which will eventually catch fire.It is a serious threat to mine safety.According to the relevant data, 90% of the mine fires caused by spontaneous combustion of coal left in the goaf of abandoned small coal mines accounted for more than 90%.To solve the problem of mine fire prevention and fire prevention and control small coal mine spontaneous combustion fire has become the focus of coal mine safety production.In view of the fire characteristics of the overlying small coal mine goaf in Xiqu Coal Mine of Xishan Coal and Power Co., Ltd., this paper puts forward a comprehensive fire prevention and fire extinguishing technology based on the information detection technology of the fire area.In the process of detecting the information of overlying small coal mine fire area in 29210 face of Xiqu Coal Mine, the theory of infrared thermal image and air leakage detection technology are studied in theory research.On the basis of experimental analysis, the critical point and tendency of spontaneous combustion of No. 8 and No. 9 coal in Xiqu Coal Mine are obtained through the temperature experiment at the intersection point of coal.In the field detection and application, by detecting the tracer gas in 29210 face of Xiqu Coal Mine, and analyzing the collected gas, the possible air leakage channel is detected.Some air leakage sources that may cause spontaneous combustion of coal have been investigated.Through the infrared thermal image technology observation to the internal heat source temperature and the surface temperature monitoring and the contrast analysis, can judge the hidden fire source existence, uses the inversion formula to calculate the small coal kiln distance,Finally, the corresponding measures are made for the areas that may cause spontaneous combustion, which provides a reliable basis for further comprehensive fire prevention and fire prevention design in Xiqu Coal Mine.
