Narrow Vein Mining - Anaconda Mining

Narrow Vein Mining. The main objective of the Narrow Vein Mining project is the development, prototyping and optimization of a new technology to facilitate the mining of steeply-dipping narrow veins, including the Romeo & Juliet Deposit and Deer Cove Deposit, located at the Point Rousse Project.

mining of narrow steeply dipping veins

mining methods are used to mine narrow, steeply dipping veins of ore [2, 3]. In some of these mines, a paste backfill composed of cemented mill tailings is used.

Federal and Provincial funding will offset the technical and financial risks of developing and optimizing a Narrow Vein Mining system for use in steeply-dipping narrow gold veins. If successfully developed, this technology has the potential to be used for similar mineral properties owned by Anaconda and other gold deposits throughout Atlantic Canada and the rest of the country.

Bulyanhulu is a narrow-vein gold mine containing gold, silver and copper mineralisation in sulphides. The mineralisation of Bulyanhulu is associated with steeply-dipping reefs. A number of distinct reefs have been identified including Reef Zero, Reef One and Reef Two.

US6857706B2 - Mining method for steeply dipping ore bodies ...

The present invention is directed to a mining method for steeply dipping orebodies. In the method, an excavator 152 is tethered to a deployment system 120 by one or more cables/umbilicals 144. The excavator 152 excavates slices 172 a-h of the orebody 100 by moving generally up-dip, down-dip or a combination thereof.
