Sandvik product line management vice-president Bruno Reumuller told sister publication Coal USA the place change miner had been specifically designed for mid-seam room and pillar operations ranging from 1.2m to 3.2m.

The power ante has been upped for the MC350 with a 470hp (350kW) cutter head drive. Total installed power on the machine is 828hp (617kW).

The machine is fully radio remote controlled, with PLC automation controls and VSD traction drive. The machine’s smarts also feature an onboard health monitoring screen.

The cutter head holds an integrated scrubber and water spray bars, both being able to be selected for left or right discharge.

The machine weighs 66 tons with a 23psi ground pressure.

Reumuller said Sandvik was also developing a larger continuous miner, the MC450, which he expects will be launched in the second quarter of 2009. The MC450 has been designed for higher seams and features greater horsepower with a 540kW cutter head.
