Abstract
Construction in Zhangyingzi ore district began in 2011 with total 18 boreholes drilled and 25,328.19 m of drilling work completed.The individual occurrence is steeper and the drilling deviation occurs easily when drilling this layer,which increases the construction difficulty.The 1.25° screw and 95 mm surface-set diamond single pipe drilling technology were selected to correct the deviation twice and the geological requirements were met finally.关键词
