摘　　要：为解决低透气性突出煤层煤巷掘进过程中煤与瓦斯突出指标值经常超限、掘进速度慢等问题,提出了深孔预裂爆破增透技术。结果表明,五轮山煤矿1805运输顺槽采用该技术后,大大提高了矿井生产效率,实现了快速安全掘进。In order to solve the problems that the index of coal and gas outburst frequently overrun, the excavating velocity of coal drift is slow in low permeability coal seams, comes up the technique of deep hole presplitting blasting. The results show that after using this technique at 1805 working face in Wulunshan coal mine, mine production efficiency was greatly improved, the fast and safe excavating was realized.
