黑龙江省嫩北农场金铜矿普查钻探施工技术应用

Application of gold and copper survey drilling technology in Nenbei farm, Heilongjiang Province

黑龙江省嫩北农场金铜矿区,通过地质钻探技术验证物探与化探异常区域,为地质勘查工作提供直观的资料,矿区地层复杂,岩层较硬,钻具易磨损,施工难度大。针对该矿区地层特点,从设备选型、钻孔结构、套管、钻头选择、冲洗液等方面采取相适应的施工工艺及技术措施,取得了较好的效果。总结的经验和体会将对今后的钻探施工有所帮助。

Nenbei farm gold copper mining area in Heilongjiang Province, geophysical and geochemical anomalies are verified through the geological drilling technology area, provide intuitive data for the work of geological exploration, mining complex stratum, rock hard, tool wear, the construction is difficult. According to the characteristics of the strata in the mining area, the suitable construction technology and technical measures are adopted from the aspects of equipment selection, drilling structure, casing, drill selection, washing liquid, etc. The summary of experience and experience will be helpful for future drilling.
