Featuring the Boart Longyear underground exploration technology like LM 700 feed frame, the new MDR700 rig is designed to offer wide drilling angles, quick setup, easy operation and maintenance.

The rig’s integrated positioner and turntable allows it to offer wide drilling angles and make easier the positioning and drilling a series of holes, the company said.

Additional features of the easily deployable MDR700 rig include articulations with three turning points to enable drilling 270 degrees horizontally and vertically up to vertically down.

The new rig also comprises safety controls, which include a dual emergency braking system as well as an engine fire suppression system to meet the advanced underground mine standards.

Powered by a 90kW electric motor, the MDR700 rig can be easily moved from hole to hole using an agile Manitou diesel-powered four-wheel drive carrier that features three available steering modes.

Integrated with multiple cameras for improved visibility and safety, the new tool has a capacity to move at up to 10 km/h and has maintenance-friendly layout to provide easy hydraulic servicing access.

Additional features of MDR700 include a rod handler and optional drill control interface (DCi) that offers semi-automated drilling, rod feed and pull functions.
