摘要: 瓦斯抽放是我國治理瓦斯災害的主要措施,目前抽放率較低．采用控制爆破技術進行提高瓦斯抽放效果的研究,解決了在高瓦斯煤層爆破的安全起爆、長水平炮孔中的裝藥技術和炸藥品種的選擇等問題．爆破后瓦斯自排量較非爆區提高5倍以上,抽放率提高明顯,抽放時間縮短1/3以上．

Abstract: Gas pre-drainage is the main solution to solve gas disaster problems. The efficiency of gas pre-drainage, however, is low by far. The method of controlled blasting was investigated to improve the effect of gas pre-drainage. Such problems as safe ignition in high-gas coal bed, charging technique in a long horizontal borehole, and selection of explosives were solved. After the blasting, the amount of gas selfdrainage is more than 5 times that in the non-blasting area, the efficiency of gas pre-drainage is improved, and pre-drainage time is less than 2/3 of the original time.
