Sandvik is introducing its next generation bolter miner for longwall mining, featuring the latest bolting technologies to increase productivity, improve safety and reduce costs.

Adding onto 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 digitalisation to enhance safety and efficiency, Sandvik is advancing bolting technology with innovative solutions designed to automate the bolting process.

The fully automated cutting cycle known as Cutronic, allows for consistent, faster and more accurate advancement, significantly reducing panel development time in stable ground conditions. This enhances operational efficiency as well as reducing wear and tear on Sandvik MB672, extending its service life and reducing its operational costs.

The machine features an optimised ergonomic operator platform and is available in both high and low operational configurations, each designed to meet specific operational needs.

Sandvik Mining underground continuous mining product line management vice president Uwe Restner comments on the bolter miner.

“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,” he said.

“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, 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 process, combined with comprehensive parts and service offering, helps customers remove risk from their operations.
