APPLICATION OF ROCK DREDGE TO COBALT-RICH CRUST INVESTIGATION
-
摘要:
岩石拖网是一种获取结壳和岩石样品的常规地质取样设备，广泛应用于富钴结壳调查和海洋区域地质调查。重点了阐述岩石拖网工作方法、位置精度控制和安全措施，并通过实例说明岩石拖网的成功应用。探讨了进一步高岩石拖网的安全性、成功率和定位精度，使其成为富钴结壳调查中浅钻调查的补充，弥补浅钻调查获取样品量少的不足。
Abstract:The rock dredge, as a kind of conventional geological sampling equipment for crust and rock sampling, is widely applied in cobalt-rich crust investigation as well as marine geological survey. This paper made a simple introduction to the equipment with emphasis on the working methods, accuracy control and accident prevention. More discussion is contributed to safety control, success rate, and positioning accuracy for dredging. As a supplement to drilling, it can obtain more bottom samples as well as the cobalt-rich crust.
