【摘要】 BZXJ是设计钻探深度为200m的超轻型冰岩芯机械钻机。该钻机总重量130kg,其中动力钻头部分仅重11kg。设备总体三维体积不大于1.2×0.4×0.4m。切削时消耗功率200W。平均切削速度为8—10mm/s。1990年11月应用该钻在天山1号冰川成功地完成了一次冰川透底钻探。在顶部40m,钻探进尺速度为5—6m/h,90m平均进尺速度为3m/h。实践证明,这种钻机具有重量轻、体积小、运输便利、操作简单、钻探效率高、岩芯质量好等优点,适于在高寒地区冰川上开展冰岩芯钻取工作。更多还原

【Abstract】 BZXJ is a type of super light-weight core drill capable of drilling to 100-200 m depth in cold ice. The weight of this complete drill system is 130 kg, in which the dynamic drill head only weights 11 kg. The three dimensional volume of the drill system is no more than 1.2×0.4×0.4 m. It consumes power of 200 W with mean cutting speed of 8-10 mm·s-1 when cutting the ice. A core till the bedrock was successfully completed on Nov. 1990 at Giacier No.l, Tianshan, China. In the upper part of 40 m of the glacier, the drilling speed can reach to 5-6 m ·hr-1, the average drilling speed in the range of 90 m depth is about 5-6 m ·hr-1. The practice demonstrated that it posses advantages of light weight, less volume, easy to transport, simple for handling, fast operation and high quality of coring etc., and is suitable for conducting core drilling on the glaciers at high altitude.更多还原
