New roadheader was presented to the coal mining industry during February 2013


At Sandvik's Competence center for mechanical cutting in Zeltweg, Austria, a new roadheader was presented to the coal mining industry during February 2013. Engineers from many coal mines in Poland and the Czech Republic, as well as trade press editors witnessed the workshop trials, taking place inside a 15 m long test tunnel.

The machine - called MR341 - is the newest addition to the roadheader family. It is a completely modernized version of the well-proven MR300 series of roadheaders. The first MR341 is designed for the European coal mining industry and features a number of safety devices, such as radio remote control for all machine functions, integrated dust collection ductings, and large working platforms to install roof support.

This machine is essentially a combination of a roadheader and a roof bolting machine. A large bolting platform (optional) is mounted on top of the roadheader and slides forward once cutting is completed to bring the roof support arch manipulator and the roof bolter into position. This way, roof support installation can be performed easily and safely. During a three-months trial at OKD's CSM mine in the Czech Republic, this concept will be able to demonstrate its benefits!
