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。
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.
