Abstract

Abstract

With the support of a underground diamond drilling project by Guizhou Jinfeng Mining Co.， Ltd.， a series of technical problems encountered in underground drilling， such as equipment selection， inner pipe transportation， hole deviation control， hole cementation， etc. were addressed through adjustment of drilling processes and parameters， leading to good drilling results. Summarization and discussion are conducted on underground drilling technology suitable for Zhenfeng Lannigou gold mine so as to provide reference for underground drilling under similar formation conditions.
