en.Wedoany.com Reported - The Bolashak (Болашак) mine of the Donskoy Ore Mining and Processing Plant, part of the ERG Group, will serve as a pilot site for the introduction of Sublevel Caving (SLC) technology.

Sublevel caving is an underground mining method widely used in deep mines worldwide. Its core principle involves dividing the ore body into horizontal layers, or sublevels, to more precisely control the rock caving process. This technology requires a high level of mechanization and automation.

To promote this technology, the company has procured modern equipment that will perform tunneling and extraction tasks, reducing the burden on personnel. Some of this equipment is already in operation. Previously, parts of the mine used the GSC scraper system. As mining depth increases, the geological conditions become more complex, and there is a need to organize safer, more stable, and efficient mining operations, which has driven the transition to the new method.

The full-scale implementation of SLC technology requires several years of thorough preparation. During this period, the Donskoy Ore Mining and Processing Plant conducted geomechanical studies, designed new mining areas, upgraded infrastructure, procured specialized equipment, and trained employees in the operation of the new system. The transition to sublevel caving is expected to reduce ore losses, help stabilize production volumes, and enable the development of previously inaccessible ore blocks.
