New features deliver real benefits

Sandvik DD212 is a compact drill solution enabling mines to open smaller tunnel sections and benefiting from increased levels of productivity with more meters advanced. Based on factory and field tests, the Sandvik DD212 delivers up to 20 % reduction in boom positioning time per face, about 15 % improvement in drill penetration rate, whilst its 3 % improved pull out ratio can result in up to 10 cm greater advance per face when compared to similar equipment.

The machine reached 93 % mechanical availability during its mine site test period, accumulating 300 hours percussion within 2.5 month operation. The drill provides great performance with net penetration rate, drill quality and rock tools improvements with zero drill rods jammed during the test period.

Sandvik DD212 is equipped with superior new features

·       New drilling control system THC562: with torque control and reaming hole selection, that enables the DD212 to provide increased drilling performance, yet reduces the wear on both the rock drill and rock tools.

·       New intelligent boom SB20i: for accurate hole electronic positioning enabling the precise and fast navigation of drill feed and tool, with automatic parallelism and instrumentation for hole angle measurements. The boom offers large face drill coverage from 6 m² to 25 m², thanks to the one-meter boom extension and the 2 rotation actuators narrow vein type.

 

The right rig for the right job

Sandvik DD212 comes with specific features and benefits for the application for which it is designed.

·       The development drill has an extended TF feed 3.66 m rod which optimizes advance/round, whilst its RDX5 rock drill provides fast drilling cycle time and low operating costs.

·       The specific compact and versatile CFX telescopic feed can retract from 1.82 m to 3.66 m and enhances multipurpose operations in small of 2.5 m x 2.5 m to 3.5 m x 3.5 m tunnel sizes. The DD212 delivers accurate face drilling, cross cutting and bolting and enables mines to open smaller tunnel sections, reducing overbreak, dilution and drilling costs.

The new DD212 brings operational safety and versatility for tackling different applications, precise electronic positioning, ergonomic operator interface, data monitoring, all leading to superior pull-out ratio and reduced tool consumption, ensuring that the new DD212 delivers the best fit in narrow vein drilling.
