Coal mine continuous miner MIKRUS series

The MIKRUS is an innovative longwall system, destined for difficult mining and geological conditions and allowing for mining thin coal seams, using cutting and loading head and the AFC integrally coupled with it. The system is equipped with the GUŁ-500 cutting and loading head with two cutting drums. The GUŁ–500 cutting and loading machine is designed for bidirectional cutting and loading coal in thin seams in longwall mines, where seams are longitudinally inclined up to ± 35°, and transversally up to ± 20°. Cutting height range is dependent on the cutting drum diameter, ranging from 1.1 m to 1.5 m. The GUŁ–500 is moved along the sidewall by a haulage system, which is powered by electric motors fed from frequency converters located in roadways. The GUŁ–500 is functionally associated with the system of pipes laid in the AFC supports.
