某矿以炸药爆破方式剥离矿岩,因岩体局部节理裂隙发育,严重影响爆破效果和效率,尝试利用钻孔电视对钻孔的360°孔壁进行无扰动的原位连续摄像,分析岩层结构和节理裂隙,研究了裂隙发育对大块率的影响规律,就装药结构和爆破方案的改善进行了探讨。
A mine exploded with mineral explosives blasting, due to the development of local joints and fractures of rock mass, seriously affecting the blasting efficiency and efficiency, trying to use drilling television on the bore hole 360 ° without disturbance in situ continuous imaging, analysis of rock structure And joint fissure, the influence of crack development on bulk rate was studied, and the improvement of charge structure and blasting scheme was discussed.
