Sandvik MB series bolter miners are electrical- ly powered, track-mounted continuous mining machines designed to excavate roadways and install roof bolts simultaneously. They are saf- er, uniquely efficient, high-capacity solutions for both rapid entry development in longwall mining and full-scale production in room-and- pillar mining. Since the cutter drum is mounted on a hydraulically actuated sliding frame, it is able to sump into the face independently of the mainframe and tracks. And since the roof and rib bolters are mounted on the stationary mainframe, they can be operated throughout...

CONTINUOUS MINERS Our electrically-powered, track-mounted The machines are in flameproof design, continuous miners are designed to cut coal and according to country regulations, such as soft minerals continuous, eliminating the need MSHA (USA) and SANS (South Africa). for drill-and-blast. Using advanced cutting technology, they cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. Extremely productive and reliable, they are used for full-scale production in room-andpillar operations. Sandvik Offering Guide 2015 | Mechanical...

BOXHOLE BORERS Sandvik boxhole borers are designed to bore circular passages blind and full face into inaccessible zones. With a diameter of 1,600 mm, they are capable of boring shafts up to 50 meters long at inclinations of up to 70˚ through very hard rock formations. Exceptionally compact and easy to set up, they are an excellent solution for boring ore passes, ventilation holes, manways, etc., and can also be vital for rescue operations.

REEF MINERS Sandvik reef miners are unique, low-profile continuous mining machines designed to extract highly abrasive ores from low reefs and seams underground and to install rock bolts simultaneously. Operated by radio remote control, they have a rotating cutter head that sweeps from side to side, mining the ore by the undercut method. The machine gathers the broken ore simultaneously and conveys it back to the haulage system in a continual process that greatly improves safety, productivity and overall economy.
