| 摘 要： | 云南省兰坪县中排乡李子坪铅锌矿详勘施工中，由于地层破碎带较发育，采用绳索取心钻进岩心采取率仍很低，无法满足设计要求。通过设计导流底喷钻头及相应的冲洗液，调整钻进参数等技术措施，取得了较好的效果，确保了工程质量。

| Abstract: | In the detailed exploration of Liziping lead-zinc mine in Yunnan Province, because the formation fracture zone is developed, the core recovery rate is very low by using the wire-line coring drilling, which can not meet the design require-ments.By the technical measures of design of diversion bottom jetting drill bit and the supporting flushing fluid and adjust-ment of drilling parameters, good results were achieved to ensure the engineering quality. |
