Sandvik Advances Further in Longwall Mining

Sandvik continues its successful development of equipment for longwall mining with the launch of its next generation Sandvik MB670-1 bolter miner. The new Sandvik MB670-1 increases productivity, reduces total cost of ownership and improves safety andergonomics for operators.

This upgraded bolter miner, developed out of the proven and reliable Sandvik MB670, is purpose-built for longwall mining. The fully automatic cutting cycle results in constant and faster advances, shortening panel development times in stable ground conditions by up to 30% and ensuring smoother mine floor conditions. Sandvik MB670-1 itself suffers less wear and tear. All of this increases productivity and lowers total cost of ownership.

"Our new Sandvik MB670-1 bolter miner has an innovative sump frame mechanism that incorporates cutting and bolting, allowing coal cutting and ground support installation simultaneously," says Bruno Reumueller, Product Line Manager, Underground Coal and Minerals, Sandvik Mining. "While the machine is stabilised for installing the ground support, the sump frame mechanism continues to move forward to cut out the next cycle.

"This enables our customers to get more out of their mine. Sandvik initiated invention of the bolter miner concept 25 years ago, and we are rapidly approaching 300 bolter miners in operation today. Our patented design is proof that our range of bolter miners helps our customers drive down their total cost of ownership and improve productivity. The new Sandvik MB670-1 is no exception."

Sandvik ensures that customers obtain everything they need for longwall development, from excavation, support and loading products to transportation and logistics. Sandvik bolter miners simultaneously cut, support, gather material and convey it into shuttle cars, coal haulers or a continuous haulage system so that it’s ready for transport.

This, coupled with a comprehensive parts and service offering, helps customers remove risk from their operations. Highly trained, expert engineers from Sandvik provide the right parts and service for safe operation, low operating costs and long service life.
