Anaconda Mining partners in innovative narrow vein mining research project. Anaconda Mining has commenced a research and development project to develop, prototype and optimize a new technology to mine steeply-dipping narrow gold veins, that cannot be mined cost-effectively with existing technologies. The company has subcontracted expertise of ...
The ideal drilling length of approximately 15 m (49 ft) is restrained due to the narrowness of the vein and the hole deviation. Problem Between Levels 7 and 8, the spacing is 85 m (279 ft), which: extends the required time to mine a stope and to fully recover the ore stockpile; and

In steeply-dipping ore bodies, such as lodes of tin, the stopes become long narrow near-vertical spaces, which, if one reaches the surface is known as a Gunnis or Coffen . [1]
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...
Federal and provincial funding will offset the technical and financial risks of developing and optimising 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 ...
Narrow vein underground mining ... the overall dip and dip direction of the vein to rotate the input data to a sub-horizontal plane prior to modelling. Once rotated, this data can be modelled with grids and the output triangulation rotated back to its original position.
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. The excavator can be automated.
This consists of a network of very narrow, steeply dipping veins which aren't conducive to economic recovery through conventional selective mining methods. However, following its presentation at the Disrupt Mining event in 2019, the team realized that SMD could benefit many other operations too. Read the Full Article all news Meet the Foresight 50
stopes for narrow-vein vertical mining methods Designed specifically for use in narrow vein, steeply dipping ore bodies, Deswik.ASD quickly generates detailed stope shapes that are traditionally designed manually. Working from a geological block model, the tool automates the process of generating sectional slices through the ore body.
The mining cost is reduced from CNY 158.88 to CNY 104.35 per tonne. This mining method has the potential to be widely used to exploit similar orebodies. 1 Introduction Gently-dipping narrow veins are those with a dip angle less than 30° and a thickness between 0.8 and 4 m.

There are several mining methods that can be used for narrow, steeply-dipping veins like those at our Ying and GC operations. The most cost-effective narrow vein mining technique is shrinkage stoping. This approach allows the development of large stopes, thereby reducing the amount of development required relative to stope volumes.
Carbon rich graphite deposits found in Sri Lanka are of inorganic origin and they occur as narrow steeply dipping veins. The vein width of these deposits varies from a few centimetres to metres, with an average vein thickness of 1 m. It is believed that the carbon rich fluid intruded into fracture zones under high pressure and the temperature has crystallised into graphite.

Veins mined by these methods typically range from 0.20 m to 2 m (0.65 to 6.5 ft) and are usually higher grade material. Mucking is accomplished by the use of appropriate sized slusher. Shrinkage mining is practised in ore zones that are steeply dipping and …
Backfill plays a major role in narrow vein mining by providing support and stabilizing the ground. It can increase recovery and help avoid leaving voids unfilled. Using paste fill also reduces the quantity of tailings that need to be stored in surface impounds, which is better for the environment, less risky and reduces waste management costs.
BACKGROUND OF THE INVENTION Considerable amounts ofvaluable metals are contained in steeply dipping ore bodies, particularly narrow vein deposits. Such ore bodies typically have a dip of about 350 or more 10 and more typically of about 450 or more, have thicknesses from several inches to several few feet, and are normally in hard or high ...
