摘　　要：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 used blasting to strip rock. Because of the development of local rock joints and fissures, blasting effect and efficiency were seriously effected. It was proposed to use borehole TV to take the un-impacted in-situ photograph of the internal wall of the borehole for analyzing the stratum structure, joint and fissure. The effect of crack growth on the bulk yield was studied. The improvement of charge structure and blasting scheme are discussed.
