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 percent 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 stabilized 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.
Coal India Secures First-Of-Its-Kind Digital Deal
Coal India Limited (CIL) has appointed Accenture Solutions to digitally transform seven of its open-cast mines as the company strives to improve performance and increase coal production. Accenture is due to lay down digitalisation groundwork until March 2022.
The deal aims to increase coal production by 100 million tonnes (MT) by the end of FY’23. Once the minimum quantity has been surpassed, an agreed sum will be paid to the consultant for every additional sum of coal produced. This success fee will only be paid on the procurement of the minimum assured quantity.
The move will see heavy earth moving machinery (HEMM) fitted with digital sensors to monitor performance efficiency at all levels. Additionally, modern data analytic techniques aim to increase mine productivity and project monitoring through functional system management and effective observation.
An Exciting Venture For Global Mining
CIL, which aims to provide energy security in an environmentally and socially sustainable manner, hopes the move will help transform the entire business of mining operations and ensure higher volumes of coal are acquired at a lower cost.
“This is a first of its kind initiative by the company utilising digitalisation to ramp up coal output,” CIL has said.
A Digital Step Towards Enhanced Performance
Digitalisation is expected to take place at open-cast mines in Kusmunda, Gevra, Dipka of Southern Eastern Coalfields (SECL), Migahi, Jayant, Dudhichua, and Khadia of Northern Coalfields (NCL). Nearly 32% (188 MT) of CIL’s 596 MT output in FY’21 was accounted for by the seven selected mines. However, this new deal is set to see a large increase following the subsequent digital changes due to be made.
“Learning from the outcome and success of this model, we may replicate it in our other large mines,” says CIL, optimistic about the future following the modernisation of their mining.
It is expected that the move will help address roadblocks and guarantee corrective measures are put into place, ensuring the company is able to move forward with its aim of increasing output whilst remaining sustainable and eco-friendly.
