摘要
从钻探器具选择、钻探硐室设计、钻孔结构、钻具级配、钻进参数、冲洗液、钻头参数等方面总结了江西德兴银山铜铅锌矿山接替资源勘探中在坑道内进行中深斜孔钻探的工艺技术。
The replacement resource prospecting of copper,lead and zinc mine was made in Jiangxi.The paper summed up the drilling technology of medium-length inclined hole in tunnel about drilling tool selection,drilling chamber,borehole structure,drilling tool grading,drilling parameter,washing fluid and drilling bit parameter.
