Bolter miners

Sandvik MB670 bolter miner

Sandvik bolter miners are hydraulically or electrically powered high-capacity machines for safe and efficient roadway excavation and roof bolt installation in underground coal and soft mineral mines.

Sandvik bolter miners combine the basic characteristics of wide-head continuous miners with special design features for cutting, loading and ground support. These flameproof (FLP) and non-flameproof miners offer you a unique solution for rapid entry development of longwall developments as well as full-scale production in room and pillar operations. The FLP design complies with the key national or regional requirements, such as MA (China), DGMS (India), ANZEX (Australia), GOST (CIS), ATEX (Europe), SANS (South Africa) and MSHA (USA).
