摘要
为矿产勘察开发提出完整可靠的选矿验证 ,资源量验证及岩土力学原始资料 ,引进三套管 (NQ3)取心工艺并进行了应用试验 ,重点介绍了该工艺的原理以及在金矿勘查60°斜孔施工中的应用。
In order to provide ore-dressing validation, resource-quantity validation and source material of rock-soil mechanics in integrity and credibility, the imported NQ 3 core boring technics is practically applied. Especially, the presentation of the technical principle and the application under construction of 60°-inclined hole in the exploration of gold deposits are given.
