摘要
对切缝药包用于岩石定向断裂爆破进行了一定的研究,对相关爆破参数进行了设计,并利用模型试验进行验证,实验结果表明切缝药包的定向断裂控制效果好。现场试验也表明该法是一种比较理想的断裂控制爆破技术。最后指明该技术有待进一步研究的方向。
In this paper, the mechanism of the orientation fracture blasting with slit-charge in rock is studied; the blasting parameters are designed and tested by model test in laboratory and the field test. The results show that the orientation fracture controlled blasting with slit-charge is a good means in excavating tunnels or cutting rock. It gives references to field application.
