Abstract:
In Velenje Coal Mine we construct annually up to 6000 m of new roadways for the production process needs. Almost all roadways are made in coal seam with a conventional method, by cutting the profile in phases and installing combined steel arched and wood support system. The roadways are constructed with GPK PV machines, which were developed with partners and adapted to our specific conditions. We have also developed a new PL PV-08 steel arches feeder, which significantly contributes to the humanization and safety in the work process. On almost each preparatory site we have installed HTZ coal crusher, which was developed with our own knowledge. It is located on the double-chain conveyor directly behind the road header. Crushing of coal at the preparatory site is crucial for the implementation of automatization. Crushed coal can be transported via conveyor paths with reduced risk of causing failures to the transportation lines. Coal is crushed on first or second double-chain conveyor and transported further on the conveyor system. With the introduction of crushing and automatization of coal transport routes from preparatory sites, we reduced the cost of the roadway construction process, thus less workforce is needed.
