| 摘 要： | 在海南岛东部滨浅海砂矿资源调查中，应用绳索锤击取心浅钻技术实施20 m浅钻，取得了较好的效果。实践证明，这种浅钻技术是获取浅层地质实物资料、验证地下信息推断与解释，最终圈定矿体、计算储量、评估品位的有效手段。介绍了这种结构简单、扰动较小的地质浅钻技术及其在生产中的应用。

| 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. |
