| Abstract:In the littoral placer resource investigation in the east of Hainan Island, good results were achieved in the application of cord hammer coring shallow drilling technology for 20m shallow drilling. The practice has proved that this shallow drilling technique is an effective means to obtain the shallow geological material data, verify the underground information inference and interpretation for the final delineation of the ore body, reserves calculation and grade assessment. This paper introduces the shallow geological drilling technology with such a simple structure and small disturbances along with its application in production. |
