SALT LAKE CITY, Utah - Boart Longyear
announced the launch of the new MDR700, the next generation underground coring rig with advanced mobility. The MDR700 is a powerful rig that utilizes proven Boart LongyearTM
underground exploration technology like the LM™ 700 feed frame and offers wide drilling angles, quick setup, easy operation and maintenance, advanced mobility and engineered safety controls.
The integrated positioner and turntable offer extremely wide drilling angles and impressive reach to make positioning and drilling a series of holes easier. Operators can drill 270° horizontally and vertically up to vertically down. The MDR700 also allows you to drill in a spherical manner without having to reposition the unit.

Setup is quick and easy with the fully hydraulic positioning system and handheld remote controller. The rig moves are faster and easier with the four wheel drive Manitou carrier with diesel engine. In a study where the rig was moved 500 meters, the average time to move the MDR700 rig from hole to hole proved to be 80% faster than a regular underground exploration rig. And the MDR700's maintenance friendly layout provides easy access for hydraulic servicing.
The carrier features three steering modes so maneuvering the rig underground is easier and faster – up to speeds of 10 km/h. The four wheel steering allows for better turning radius in restricted spaces. The two wheel steering is for on-road driving. And the crab-like movement makes the carrier agile for lateral approaches and delicate exits. For improved visibility and safety, multiple cameras are located on the rig and viewed/monitored from the cabin of the carrier.
The MDR700 is powered by a 90kW electric motor and features the proven Boart Longyear LM700 feed frame delivering 81.4 kN of pullback. The MDR700, coupled with the proven HQ™ rotation unit, gets you to the target productively in all coring diameters up to HQ.
The drill rig also features a breakout system on the rotation unit that uses high pressure oil and gear rack assistance to effortlessly break rod joints. The MDR700's engineered safety controls include a dual emergency braking system and an engine fire suppression system so it meets the most advanced underground mine standards. The spring close and hydraulic open rod clamp ensures failsafe operation in case of a burst hose or power loss.
The rig also offers exclusive features like a patented rod handler and optional drill control interface (DCi) that takes safety as well as productivity to the next level. The DCi offers semi-automated drilling, rod feed and pull functions and controls while controlling both the rod handler and the rig.
The rod handler sets new standards for ease of use, versatility, and most importantly, safety. Utilizing innovative high capacity springs acting on three tungsten carbide insert jaws, the rod handler isolates the driller from the hazards of manual rod handling. And the smart hydraulics provides synchronized control between the rotation unit and the foot clamp for faster and safer rod handling.
