The new 2711 class of drills are specifically aimed at the requirements of specialist mining companies as well as drill and blast contractors who require safe, productive, mobile rigs for use in narrow vein and other confined areas.
The new drills are simple and safe to operate, with robust components and provide an excellent performance to ownership cost ratio.
The 2711 class drills have been developed to cater to the needs of certain mining and tunnelling operations. Selective mining methods and small tunnel developments have proved to be a good way to extract ore economically and control the dilution when ore is distributed in narrow veins typically less than 2m-3m in width. Sandvik's narrow size underground drills are thus designed specifically with the requirements of drilling narrow vein drifts and that of small tunnels projects in mind.
The drills are equipped with Sandvik's Fleet Data Monitoring systems, enabling mines and tunnelling contractors to improve fleet performance and management.
The new 2711 drill family provides, in one modular platform, accurate drilling with high performance, large coverage and drill capacity, with enhanced product safety and excellent mobility, tramming smoothly into small mining drifts and tunnels.
The selected reliable components and simple electro-hydraulic systems are designed to be used in conjunction with Sandvik's comprehensive range of underground drills, loaders and trucks, all being supported worldwide by the Sandvik network.
The new series consists of three drill types using a common platform covering different applications: namely development drilling DD2711, rock support bolting DS2711 and long hole production drilling DL2711 and DL2721.
Sandvik DD2711
The DD2711 is a compact and flexible single boom electro-hydraulic jumbo for mining development and construction in small and medium-size tunnels with a minimum cross-section of 2.7m x 2.7m.
The highly versatile boom delivers large coverage and fully automatic parallelism for fast and accurate face drilling, while 20kW of drilling percussion power is provided through Sandvik's HXL5 rock drill.
It is designed for underground hard rock applications that require high capacity and reliability in development blast holes ranging from 3.7m to 4.3m in length.
The DD2711 is in effect a simple premium drill, compact, versatile and designed for global needs; it provides an excellent drilling performance to cost ratio in small drifts, improves safety and lowers operating costs.
Sandvik DS2711
DS2711 is a one-man operated electro-hydraulic, fully mechanized bolter for rock reinforcement in underground hard rock mines. The operator works from supported ground while protected under a FOPS certified canopy structure.
Mechanisation of the bolting process ensures efficient, constant and durable rock bolts integrity. The DS2711 provides an excellent bolting performance to cost ratio for small and medium-size tunnels with minimum cross-section of 2.7m wide and 3.0m high.
Designed with proven and reliable components, the DS2711 provides high reach and is able to install all types of mechanized rock bolts ranging in length from 1.5m to 2.4m. It is in effect a small premium bolter, compact, mobile and designed for global needs.
The next addition to the range will happen in 2020 with Sandvik DL2711 and DL2721 long hole drills.
