摘要
Drilling is the only technical means to access the underground physical information, verify the inference and interpretation of underground information, define orebody and reserves, and evaluate the ore grade. It is an important technical support for materialization of major exploration results. With the implementation of the state major scientific program\" Chinese Continental Scientific Drilling Project\" CCSD #1 Well (a drilling depth up to 5 158 m). China’s geo-drilling technology has made great advances through research and application in wire-line core drilling, fluid powered DTH drilling, reverse circulation drilling, etc., which provide advanced drilling technology and equipment for geological and mineral exploration in China.
