摘要
铲子坪金矿为板溪群构造破碎带蚀变岩型金矿床。钻探施工中，因地层复杂、岩石坚硬及孔斜超差，严重影响着钻探效率和质量。１９８８年后，积极引入受控定向钻探等新技术，因地制宜、综合治理，工艺技术逐渐配套完善，取得了较好的地质成果与社会经济效益，为矿区地质工作的全面开展提供了有效的技术保证。
Chanziping gold deposit belongs to altered rock type one in fracture zone occurred in Banxi Group.In the process of drilling,the complexity of the strata,the hardness of the rocks and the hole overdeflection severely affect the quality and the efficiency of the drilling.From the year of 1988 on , controlled directional drilling and other new technology were actively introduced in, Comprehensive improvments were made in the light of local conditions to form gradually a complete set of technology,which had lead to fruitful geological re-sults and social一economic benefit,and provided effecient technology guarantee for the overall carrying一out of the geological work in the ore district.
