Sandvik supplies Top Hammer XL drilling technology for Tapojärvi at Yara’s Siilinjärvi mine in Finland

The rigs are remotely operated by the AutoMine^® system and accompanied by a comprehensive package of solutions for maintenance, rock tools and OptiMine^® information management. The products in the delivery scope support the alliance on their digitalization and automation journey towards more productive, efficient and sustainable mining.

The Finnish mining and industrial services specialist Tapojärvi Oy is initiating a 10-year strategic alliance with Yara’s Siilinjärvi open pit mine starting on January 1, 2022. The collaboration has begun with a two-year preparation phase, which focuses on the planning, management and development of the mining operations. The agreement covers drilling, loading and haulage operations at the mine site. Yara is a global supplier of fertilizers, industrial chemicals and environmental solutions and its Siilinjärvi mine produces the world’s purest phosphate for use as raw material in fertilizer. The goal of the alliance is continuous development of mining activities, and Sandvik’s new solutions increase production sustainability by improving drilling safety, productivity and fuel efficiency – ultimately reducing emissions that are harmful for the climate. The drilling and automation technology supplied by Sandvik will create significant opportunities for optimizing drilling operations and data-driven rock excavation.

Sandvik launched the new Top Hammer XL drilling system globally in March 2021 and Tapojärvi will be the first to begin using the innovative technology at the Siilinjärvi mine. The components of the system – a new Pantera™ DP1600i drill rig, new RD1840C rock drill and new LT90 rock tools – are all optimized to work seamlessly together in order to achieve exceptional drilling results. The key benefit of the new technology is the expansion of the application area of top hammer drilling technology to significantly larger hole sizes, up to a diameter of 178 millimeters (7 inches). Another considerable customer benefit is improved fuel efficiency compared to down-the-hole (DTH) drilling, traditionally used for holes with larger diameters.

Tapojärvi will operate all six Pantera™ DP1600i drill rigs remotely with the AutoMine^® Surface Drilling automation system designed for Sandvik’s i-series surface drill rigs. The rigs will initially be operated from remote control stations near the drilling area and at a later stage from the mine control room. Yara’s LTE communication network will be used for remote operation and data transfer.

“A single remote control station will be used for controlling the drilling operations of two rigs,” says Tapojärvi’s COO Martti Kaikkonen. “The system provides the capability to move the drill rigs from one hole to another by commanding from the remote station, and the rigs drill blastholes autonomously. Controlling the rigs from a remote center improves the working conditions of our employees. It is cleaner, more ergonomic and safer.”

OptiMine^® for Surface, a new solution for optimizing and analyzing surface drilling processes, will be used by the alliance partners for continuous improvement of their mining operations. The system produces real-time data on drilling productivity, equipment condition and availability, as well as data that can be used for predicting and developing mining operations. Together with the TIM3D drill rig navigation system, it also serves as a tool for planning drilling and blasting, quality assurance and determining rock conditions.

“Top Hammer XL, together with the AutoMine^® and OptiMine^® systems, support Tapojärvi’s technology strategy for more sustainable mining operations,” says Jari Weman, Sales Manager at Territory North East Europe, Sandvik Mining and Rock Solutions. “We are honored the alliance selected us as the drilling technology supplier and to be able to supply the mine with a solution that meets their production needs. We have cooperated with the mine since it was founded and developed many new solutions together over the years. Through this agreement, we will further develop productivity and safety in collaboration with the alliance, using Sandvik’s latest drilling technology, automation and digitalization solutions.”
