E&MJ asked Atlas Copco’s product manager for face-drilling equipment, Peter Bray, for his views on some aspects of equipment that is suitable for narrow-vein applications. “Narrow-vein mining can be divided into two main areas,” vertical/close to vertical and
The operational challenges of narrow-vein mining include controlling overbreak as the veins being mined are only 300 mm wide. Costerfield has developed methods and modified equipment to suit extraction of these veins. Productivity improvements have involved developing a stoping method and equipment to suit 1.8 m wide development drives.
The challenge to Australian narrow vein mining projects is to capitalise on work undertaken by overseas mining companies and equipment suppliers and to investigate the adaptation of low profile coal mining machinery to specialised metalliferous mining.

E&MJ looks at recent developments in specialist machines for narrow-vein mining. In the year that has passed since the last review of equipment designed specifically for narrow-vein mining environments, it has become clear that there is still strong demand from the industry worldwide for these machines.
Hard rock equipment. Hard rock equipment. We have an extensive product suite of hard rock mining equipment, including hydraulic jumbo drills, drifters, loaders, and trucks. Ideal for narrow vein applications; Joy LT-1051. Rated load capacity of 10,000 kg (22,000 lbs.)
Conventional narrow vein mining, utilising hand held methods, is expensive and requires specialised miners who are becoming a rarity. Hand held mining techniques (shrinkage stoping, leading stoping and cut and fill) have the advantage that they can be selective.
liming offers a wide range of narrow vein and small size underground drills matching very well both narrow vein drifts and small tunnels projects. optimize extraction rates and safely release blockages to improve drawpoint availability in back caving operations and narrow vein mining. A world leader in mining equipment and rock excavation.

experienced as aresult of being unable to mine only the mineralized vein. The minimum mining width possible is approximately one metre using only hand tools and 1.5 metre with narrow-seam mining equipment. While narrow mining widths provide a means of controlling grade, his selectivity comes with a higher mining cost and lowet r productivity.
It is recognised that a gently-dipping narrow vein is hard to be exploited due to the difficulties in ore drawing and operating large mining equipment in the restricted stoping space. Therefore, considerations are required to adopt an efficient mining method that is capable of dealing with the irregular boundary of
