1、高瓦斯論文:佳新煤礦1504工作面火區(qū)啟封技術及發(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,對高效高產的生產造成威脅,造成大量的資源浪費、財產損失及人員的傷亡。掌握煤炭自燃機理,研究煤層低溫氧化規(guī)律是防治煤炭自然發(fā)火的基礎。由于煤及其組分的多樣性,其氧化熱解過程中可能發(fā)生的化學反應就非常復雜。礦井煤炭自燃火災是煤礦重大災害之一,近年來井下火災事故頻發(fā),損失巨大,教訓慘痛?;饏^(qū)一旦形成,進行火區(qū)封閉與啟封危險性大,技術性強,稍有不慎,后果不堪設想。本文在廣泛閱讀低溫氧化中外文獻的基礎上,采用理論研究、實驗分析和現(xiàn)場實測三方面相結合的綜
2、合研究方法。在了解了高瓦斯煤層自燃特點的基礎基礎上根據(jù)各類防滅火技術的不同特點,綜合現(xiàn)場情況,運用逐步鎖風啟封方法對1504工作面火區(qū)進行了安全啟封。佳新煤礦主采煤層是屬于高瓦斯易自燃煤層,在正?;夭蛇^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
