1、高瓦斯論文：佳新煤礦1504工作面火區(qū)啟封技術(shù)及發(fā)火規(guī)律的研究【中文摘要】煤礦自燃問題一直困擾著我國煤礦的安全生產(chǎn),對(duì)高效高產(chǎn)的生產(chǎn)造成威脅,造成大量的資源浪費(fèi)、財(cái)產(chǎn)損失及人員的傷亡。掌握煤炭自燃機(jī)理,研究煤層低溫氧化規(guī)律是防治煤炭自然發(fā)火的基礎(chǔ)。由于煤及其組分的多樣性,其氧化熱解過程中可能發(fā)生的化學(xué)反應(yīng)就非常復(fù)雜。礦井煤炭自燃火災(zāi)是煤礦重大災(zāi)害之一,近年來井下火災(zāi)事故頻發(fā),損失巨大,教訓(xùn)慘痛?；饏^(qū)一旦形成,進(jìn)行火區(qū)封閉與啟封危險(xiǎn)性大,技術(shù)性強(qiáng),稍有不慎,后果不堪設(shè)想。本文在廣泛閱讀低溫氧化中外文獻(xiàn)的基礎(chǔ)上,采用理論研究、實(shí)驗(yàn)分析和現(xiàn)場實(shí)測三方面相結(jié)合的綜
2、合研究方法。在了解了高瓦斯煤層自燃特點(diǎn)的基礎(chǔ)基礎(chǔ)上根據(jù)各類防滅火技術(shù)的不同特點(diǎn),綜合現(xiàn)場情況,運(yùn)用逐步鎖風(fēng)啟封方法對(duì)1504工作面火區(qū)進(jìn)行了安全啟封。佳新煤礦主采煤層是屬于高瓦斯易自燃煤層,在正常回采過程中,為了確保工作面安全回采,采取單一的防滅火措施已經(jīng)不能完全有效的解決煤層自燃隱患,本文通過注氮、注膠、加快工作面推進(jìn)速度、采用束管監(jiān)測等綜合防滅火措施,確保1504工作面的安全回采?！居⑽恼緾oalspontaneouscombustionhaveplaguedourcoalminesafetyproduction,highyieldproducti
