摘要
针对试验矿井煤巷炮掘速度慢、安全性低、爆破产生粉尘和有害气体较多的问题,提出了适合试验矿井煤巷掘进的二氧化碳爆破技术,研制了二氧化碳爆破开采器,并获得国家专利。该装备的工作原理是利用液态二氧化碳瞬间发生相变产生高压,作用于周围煤(岩)体,从而实现破煤(岩)。经井下1 600 m长煤巷的掘进实践表明:二氧化碳爆破相比于传统炸药爆破,安全性高,爆破效果好,煤炭成块率可提高1倍以上,达到65%~78%;抛煤距离缩短约40%,为0~3 m;粉尘及炮烟量减少约50%,二氧化碳体积分数一般为0.02%~0.09%,一氧化碳体积分数一般为(3~16)×10~(-6);该技术能够为井下创造良好的掘进工作环境,有利于作业人员的身体健康,实现了安全高效掘进。
According to the slow drilling and blasting driving speed,low safety,dust occurred from the blasting and many harmful gas problems of the seam gateway in the trial mine,a carbon dioxide blasting technology suitable for the seam gateway driving in the trial mine was provided.A carbon dioxide blasting miner was researched and developed with the National Patent.The operation principle of the equipment was to apply the high pressure from the phase transition during the liquid carbon dioxide and then would be affected to the surrounding coal and rock mass.Therefore,the coal and rock breaking was realized.The driving experiment practices of a 1 600 m seam gateway in the underground mine showed that in comparison with the conventional blasting,the carbon dioxide blasting would have the high safety,high blasting effect and good blasting effect.The lump coal rate could be improved over 200%and would be reached at 65%~78%.The coal throw distance was reduced about 40%and was 0~3 m.The dust and blasting fume volume was reduced about 50%,the carbon dioxide volume fraction was 0.02%~0.09%generally and the carbon monoxide volume fraction was(3~16)×10~(-6) generally.All those could create an excellent driving working environment in the underground mine,could be favorable to the physical health of the operation personnel and could realize the safety and high efficient driving.
