t the needs of high efficiency and production safety, coal and gas outburst prewarning technique and puter system was introduced to longshan coal mine. The technology involved in all aspects of gas outburst prevention, including the outburst prevention technology system and safety management system. Field applications proved that: Longshan mine has enough time to prevention gas disaster with help of the prewarning system, and formulates measures contrapuntally by using the prewarning system, finally, Longshan coal mine can eliminate the outburst danger efficiently and produce safely. Keywords:gas outburst。 prewarning and forecasting。 gas disaster。 prevention and safety0前言我國(guó)是煤與瓦斯突出事故最嚴(yán)重的國(guó)家之一,突出礦井多、分布廣、突出事故多,重特大突出事故時(shí)有發(fā)生。通過(guò)大量突出事故調(diào)查發(fā)現(xiàn),防突措施落實(shí)不到位和防突管理不到位是突出事故的主要直接原因。實(shí)踐證明,通過(guò)多種途徑實(shí)現(xiàn)突出危險(xiǎn)性、隱患的超前預(yù)警和強(qiáng)化防突管理是有效防突的重要手段[15]。煤與瓦斯突出是煤炭采掘過(guò)程中易發(fā)生的一種大型動(dòng)力災(zāi)害,其突出能量大,破壞能力強(qiáng),易導(dǎo)致大規(guī)模的人員傷亡,嚴(yán)重影響著煤礦的安全生產(chǎn)和經(jīng)濟(jì)效益。要對(duì)煤與瓦斯突出進(jìn)行有效的預(yù)防和治理,首先要進(jìn)行有效的預(yù)警[6]。目前突出危險(xiǎn)性預(yù)測(cè)的常用指標(biāo)主要包括區(qū)域預(yù)測(cè)指標(biāo)和工作面預(yù)測(cè)指標(biāo),區(qū)域預(yù)測(cè)指標(biāo)分為單因素指標(biāo)法(瓦斯壓力或瓦斯含量)和綜合指標(biāo)D和K等,工作面預(yù)測(cè)指標(biāo)(鉆屑瓦斯解吸指標(biāo)、鉆孔瓦斯涌出初速度和鉆屑量指標(biāo)等)。常規(guī)的煤與瓦斯突出預(yù)測(cè)技術(shù)是抽檢式、不連續(xù)、局部的預(yù)測(cè),具有相當(dāng)大的局限性[78],這種傳統(tǒng)的煤與瓦斯突出預(yù)測(cè)技術(shù)是一種抽檢式的、不連續(xù)的、局部突出危險(xiǎn)性預(yù)測(cè)方法,某一預(yù)測(cè)指標(biāo)只能間接和部分的反映影響突出危險(xiǎn)某一因素,沒(méi)有從大的區(qū)域角度提前對(duì)瓦斯災(zāi)害及嚴(yán)重程度進(jìn)行提前預(yù)警,并建議礦井采取相應(yīng)的措施,具有相當(dāng)大的局限性。煤與瓦斯突出綜合
