Exploitation of coal in Raša mine, as one of the mines in Raša coal basin, began in 1928. In Krapan, a settlement near Raša, mining started back in 1626, but only at the time of the fascist era exploitation of coal in Raša mine experienced the real expansion. Raša coal basin in the heyday employed more than 10,000 workers, and the coal basin was distributed to almost 30 horizons i.e. floors with almost 400 km long branching transport corridors. Raša mine was closed in 1966, mainly due to the exhaustion of the site and the all-present crisis.
