摘　　要：选择鞍千矿和齐大山铁矿的主要岩种,对其矿物组成、粒度、结构构造、胶结形态、细观构造等进行显微镜下观察和描述;分析、探讨了矿岩细观组成、结构特征与其宏观磨蚀行为之间的联系,揭示了鞍千矿矿岩难钻、钻头寿命低的根本原因。Main mine rocks in both Anqian Iron Mine and Qidashan Iron Mine were studied, including observing and describing their mineral compositions, grain sizes, texture and structure, cementation modes and microscopic structure using a microscope. The relations between microscopic compositions and structural features of the mine rocks and macroscopic abrasive action were analyzed. The basic reasons for drilling＇difficulties of the mine rocks in Anqian Iron Mine and low service lives of drills were revealed.
