摘　　要：贵州松桃县高地锰矿找矿工作已全面进入勘探阶段,勘探网距为200 m×300 m,对钻孔质量要求十分严格:终孔靶点偏差不超过勘探网距的1/4,即平行勘线方向不超过50 m,垂直勘探线方向不超过75 m,对于勘查区设计孔深均超过1400 m(最深钻孔达到1950 m)的深孔而言,这种要求远远超过地质岩心钻探规程要求。贵州省地质矿产勘查开发局局属施工单位根据多年深孔施工经验,从钻机基座建设、钻孔结构及钻具组合优化、钻进参数调整、单扩孔器纠斜等方面采取保直防斜技术措施,取得了较好的效果。The exploration work for the Gaodi Manganese Mine in Songtao County,Guizhou has fully entered the exploration stage,with an exploration network distance of 200m×300m,with very strict requirements for drilling quality:the deviation of the final hole target point shall not exceed one fourth of the exploration network distance,that is,the parallel exploration line direction shall not exceed 50m,and the vertical exploration line direction shall not exceed 75m.For deep holes with a design depth of over 1400m(the deepest borehole reaches 1950m)in the exploration area,this requirement far exceeds the requirements of geological core drilling regulations.According to many years of deep hole construction experience,the construction units under Bureau of Geology and Mineral Exploration and Development Guizhou Province have taken technical measures to maintain straight and prevent deviation from the aspects of rig base construction,drilling structure and combinatorial optimization of drilling tools,drilling parameter adjustment,and single reamer deviation correction,and achieved good results.
