Russia's Kotinskaya Mine Gets Double Life from Cat~R Longwall Shields

摘要

Kotinskaya, Russia's most productive underground coal mine, has won an additional benefit from its record-breaking longwall face equipment, based around Cat~R roof supports and armored face conveyors. Caterpillar tested a shield from the mine at its manufacturing facility in liinen, Germany, and the results showed that the roof support condition justifies an additional 20,000-cycle life extension-with no major rebuild.
