摘要
文章对Φ165 mm孔径在白云鄂博铁矿不同岩性中的预裂爆破进行了探讨,通过计算得出了一些基本的爆破参数。由于白云鄂博铁矿是第一次用Φ165 mm孔径钻机靠界,文中对Φ165 mm孔径钻机在白云鄂博铁矿不同岩性中靠界提供一定理论依据,同时也总结了其它矿山预裂爆破成功的经验。
In this paper,it is discussed the presplit blasting with Φ165 mm aperture for dissimilar lithologies of Baiyunebo Iron Mine and some basic blasting parameters are obtained by calculations.On account of using drilling machine with Φ165 mm aperture to close to the boundary in Baiyunebo Iron Mine for the first time,some theory evidences for it are given.Meanwhile,some experiences of successful presplit blasting in other mines are summarized.
