摘　　要：切缝药包定向断裂控制爆破在工程方面应用比较广泛,文章大致从煤矿、其它工程应用方面进行回顾,得出切缝药包定向断裂控制爆破在煤矿瓦斯抽放、井巷掘进、石材成型等方面效果显著,提高了瓦斯流动性、提高炮孔利用率和眼痕率、减少了飞石距离、降低爆破对围岩的扰动损伤、改善了爆破效果、提高了经济效益;最后对切缝药包定向断裂控制爆破的研究进行了展望。the cutting seam cartridge directional lracture controlled blasting applies in engineering widely.We reviewed the appli- cation of the cutting seam cartridge directional fracture in coal mine and other engineering,Obtained it efficient fracture controlled blasting in ＇coal mine gas drainage,underground tunnel excavation,stone forming etc.,which improved the coal mine gas flow,increased the utilization ratio of hole and hole mark ratio,reduced the distance of flying rocks and reduced the blasting vibration damage,im- proved the blasting effect,improved the economic benefits.In the end we prospected the cutting seam cartridge directional fracture con- trolled blasting.
