摘　　要：在陡斜矿体上施工分支钻孔,不但节约钻探工作量,减少钻机搬迁、修路次数,对环境保护和提高地质找矿效果也有重要意义。主要介绍了用LZ型连续造斜器在易斜地层施工定向分支钻孔的技术和工艺。The construction of directional branch hole in steep orebody can not only save drilling workload, reduce drilling igr relocation and road repairing, but also is helpful for environmental protection and improving geological prospecting effect. This paper introduces the technology and processes of directional branch hole with LZ continuous whipstock in complex easily inclined stratigraphic.
