摘要(Abstract):

通过切缝药包定向断裂控制爆破的爆破机理、影响因素的研究现状,得出爆破参数的合理取值范围;由此技术的发展和工程应用的研究现状,得出切缝药包定向断裂控制爆破技术提高了爆破效果,减少了工程造价,增加了围岩的稳定性;最后对切缝药包定向断裂控制爆破的研究方向提出了几点建议。
According to cutting seam charge directional fracture controlled blasting mechanism and its influencing factors,reasonable ranges of blasting parameter values were achieved.Through development and engineering application research situation of cutting seam charge directional fracture controlled blasting technology,some results were obtained such as the blasting technology improving blasting effect,reducing the project cost,and increasing the stability of surrounding rocks.Some suggestions were put forward on research direction of cutting seam charge directional fracture controlled blasting.
