New Sandvik MB672 bolter miner set to accelerate longwall mining

Sandvik is introducing its next generation bolter miner for longwall mining. Sandvik MB672 features the latest bolting technologies to increase productivity, improve safety and ergonomics for operators and reduce total cost of ownership.

Building on the proven reliability of Sandvik MB670-1, the upgraded Sandvik MB672 is purpose-engineered for longwall mining operations. As underground coal mining continues to embrace automation and digitalization to enhance safety and efficiency, Sandvik is advancing bolting technology with innovative solutions designed to automate the bolting process. These developments mark a significant step toward achieving bolting automation in the near future.

Furthermore, the fully-automated cutting cycle, known as Cutronic®, enables consistent, faster and more accurate advancement, significantly reducing panel development time in stable ground conditions. This not only enhances operational efficiency but also reduces wear and tear on Sandvik MB672, extending its service life and reducing its operational costs. The machine, which features an optimized, ergonomic operator platform, is available in both high and low operational configurations, each designed to meet specific operational needs.

Building on a long-established innovative sump frame mechanism that integrates cutting and bolting to enable simultaneous material cutting and ground support installation, Sandvik has now taken the next step toward bolting automation, advancing mining productivity while significantly improving operator safety.

“Sandvik pioneered the bolter miner concept more than 30 years ago, and we continue to strengthen our market-leading position with more than 500 bolter miners delivered to our customers around the globe,” said Uwe Restner, Vice President Product Line Management Underground Continuous Mining at Sandvik Mining. “The new Sandvik MB672 bolter miner is setting a new benchmark in bolting automation to accelerate mining and pave the way for future autonomous machine operation.”

Sandvik supplies everything its customers need for longwall development — from underground excavation, ground support and material loading to transportation and logistics. Sandvik bolter miners simultaneously cut, support, gather material and convey it into vehicle-based or continuous haulage systems. This, coupled with a comprehensive parts and service offering, helps customers remove risk from their operations. Highly trained experts and engineers from Sandvik provide the right parts and services for nonstop operation, low operating costs and long service life.
