摘　　要：为了解决高瓦斯工作面瓦斯抽采难题,以司马煤矿1211工作面为工程研究背景,进行CO_2致裂器深孔预裂数值模拟,结果表明两致裂孔间距10m、致裂器与连接杆按照1:3连接时为最佳方案,并在1211工作面运输巷与回风巷完成致裂增透工作,验证了按该方式布置时深孔预裂增透效果较好,对司马煤矿及类似条件下深孔预裂增透技术具有很好的借鉴意义。In order to solve the problem of gas extraction in high gas face, using numerical simulation of deep-hole pre-splitting anti-reflec-tion with carbon dioxide fracturer which taking the 1211 working face of Sima coal mine as the engineering research background.To determinethe best solution that the spacing between two induced hole is 10m and the connection ratio of carbon dioxide fracturer and draw-baris 1： 3.Completed the work of fracturing and anti-reflectionin 1211 working face conveyance road and return airway.h is proved that the effect ofdeep-hole pre-splitting is better in this way, and it has great significance for deep-hole pre-splitting anti-reflection technology in Sima coalmine and similar coaditions.
