The mining method must be varied for different specific deposits. In summary, there are three dominant techniques worldwide for mining gently-dipping narrow vein: Longwall mining method: this method is suitable for mining bedding deposit with a dip less than 35 , 3-4 m thickness and poor roof.
As noted in last year’s review (Niche Machines for Narrow-Vein Mining), Boart Longyear’s focus for narrow-vein applications is on long-hole rigs for stoping. Weighing just 3.75 mt, its StopeMate pneumatic production drill is small enough to fit through a 1.3-m x 1.9-m (50 x 75-in.) opening, and can fit into a man cage with no disassembly.

Equipment The Coeur d’Alene mining district in ... is the oldest (76 years) and deepest mine in the district, producing approximately 725 t/day (800 stpd) from narrow, vertical lead-zinc-silver veins. Cut-and-fill stoping is currently employed at depths to about 2.3 km (7,500 ft) below ground ... Cross section view of 30 Vein mining showing ...
narrow vein mining, vein characteristics and grade can change rapidly. Local resource models rapidly become outdated as information is collected from drifting along veins. Short term modelling requires vein models to be rebuilt regularly. Monthly rebuilds fit the reconciliation and short term planning cycles, and lead to better quality

Keywords – narrow-vein mining, bulk methods, underground pre-concentration, backfill, economics 1. Introduction The majority of Canadian hard-rock narrow-vein mines are mature, and face the need to mine deeper deposits in the face of increasing costs and declining grades.
The use of explosives in underground mining has its drawbacks, particularly in the case of thin or narrow vein type deposits. Due to that, there is a need to develop more discriminative and safe rock-breaking technologies. Mechanical rock splitting seems to be one of the most promising avenues in this respect. This paper describes briefly principles and features of radial-axial splitters.
The Robbins 34RH C wide is a low profile small diameter raise drill which is suitable for use in upward boxhole boring, and conventional raiseboring and downreaming. It is highly versatile, and can also be used for back filling, slot raises, and narrow vein mining applications. A wide frame is used for passing a 1060 mm reamer through the ...
Goldcorp Narrow-Vein Mining Equipment Project: The Goldcorp project in Red Lake, Ontario is Canada’s largest gold mine and has one of the world’s richest gold deposits. To operate in the mine’s unusually narrow-vein drifts, Marcotte was contracted to design and fabricate a new smaller line of its vehicle-mounted underground equipment. Challenge:
Narrow-Vein Mining Research Project. The mining industry is continually looking for ways to automate and mechanize its operations. This presents a great challenge for narrow-vein operations. The actual mining parameters and existing mechanized equipment make profitability difficult to achieve. It is clear that the future of narrow-vein mines depends on the development of innovative extraction methods and equipment.
The full program was completed in January 2020 and saw the company acquire modern equipment suitable for narrow vein-mining to increase mining capacity as compared with 2018, it said. The new mining mechanised fleet includes a total of 12 mini-dumpers, with 4 t and 2 t capacities, one electrohydraulic jumbo drilling machine, three LHDs and three tractors, each of which are currently …
