Sandvik unveils new DS422i cable bolter

The Sandvik DS422i

Sandvik has released the DS422i cable bolter for improved productivity, safety and process control.

The Sandvik DS422i is built on the same platform as the Sandvik DD422i, providing lower total cost of ownership through parts commonality, easy serviceability and high productivity.

It is engineered for intelligent rock reinforcement, providing seamless integration with other key underground mine systems.

Ground support is a quality-focused, statistics-driven and operations-critical process in a mine. The common denominator, which almost all cable bolter users share, is a desire for information: exactly how and where bolts were installed, how much grout was pumped, the mixing ratio of the grout used and other key details of the mechanized bolt install process. The Sandvik DS422i can provide this information, store it and pass it on to a mine’s systems for analysis through its intelligent control system and connectivity.

“Handling hole location information has long been in practice for both development and production drilling, but not yet properly used in bolting,” Anssi Kouhia, product manager for Sandvik DS422i, said. “Our latest intelligent product brings the potential of data integration to our customers.”

Petri Mannonen, product manager for Optimine products, said efficient task management with regards to bolter operation is usually more complex to achieve compared to other drill and blast cycle operations.

“In addition to managing that the machine has a free heading to operate in, the bolter also has to manage the replenishment of concrete and other consumables,” she said. “Our Optimine task management package provides great advances in this respect through two-way communication with the task management system.”

The cable bolter also features automatic rod handling, a quiet and ergonomic cabin and Sandvik intelligent controls and automation with both operator assistive and automated functions.

In addition, the new Sandvik RD414 rock drill provides a 30 percent higher penetration rate and a longer shank and drill steel life through its advanced rock drilling technology.
