Sandvik Mining and Rock Technology has released its latest class of narrow size drills.

The 2711 model is aimed especially for mining ores in narrow veins less than two to three metres in length and other confined areas.

These small tunnel mining methods are an economic way to extract ore and control the ore dilution, but the right equipment is essential in these narrow veins.

Sandvik’s narrow size drills are designed specifically with these requirements in mind and are equipped with the fleet data monitoring systems, enabling mines and tunnelling contractors to improve fleet performance and management.

The 2711 provides accurate, high-performance drilling with large coverage and drill capacity and enhanced safety and mobility, particularly small mining drifts and tunnels.

It is also equipped with simple electro-hydraulic systems to be used with Sandvik’s entire range of underground drills, loaders and trucks.

This new class of drill is ideal for mining and drilling contract companies wanting smarter control of ore dilution and increasing selective process while mining.

There are three drill types available for different methods; the namely development drilling DD2711, rock support bolting DS2711 and long hold production drilling DL2711 and DL2721.

The DD2711 is a flexible single boom electro-hydraulic jumbo for mining and construction in small to medium sized tunnels, with a minimum cross section of 2.7 metres by 2.7 metres. It is designed for underground hard rock applications that require high capacity and reliability.

Sandvik has designed the DD2711 as a one-person operated fully mechanised bolter for rock reinforcement in underground hard rock mines.

The operator is protected under falling object protective structures (FOPS) and it provides an excellent bolting performance for small to medium tunnels.
