KPO-8,5

Application

The heading-and-winning machines KPO-8,5 are designed for development mining:driving of mine workings, chamber cutting, and as well as the ore extraction with a single-stall system.

In operation the machines produce mine face destruction, mucking, loading the broken muck into the reloading bunker or into the shuttle car. Moreover, these machines perform drilling of blast holes.
