DIAMO, state enterprise, branch ODRA 

DIAMO, state enterprise, ODRA branch, was established as the successor organisation of the closed mines Šverma, Heřmanice, Ostrava and Odra, i.e. the mines of the Ostrava mining district, on 1 January 1998 acquiring the J. Fučík mine and on 1 July 1999 merging the plants of František and Paskov of the Karviná and the southern part of the district. As at 1 January 2002 the ODRA branch, by sale of part of the joint-stock company OKD, a. s., in harmony with Government Resolution No. 453/2001, was joined with DIAMO, state enterprise.

The ODRA branch is in the stage of advanced attenuation of mining and includes organisational units of Mine and Surface and professional management sections, production, technology and environment protection management and economy and HR management sections.

The Surface centre manages all former mines in the Ostrava and the Petřvald basins (hereinafter ODP and PDP), in the southern part of the district – the former Paskov Mine, and in the Karviná part – the former Barbora Mine – with completed “technological liquidation of the mine”. The Surface centre further manages the waste dump, the OSTRAMO Lagoon. The Mine centre manages the mines of the Jeremenko and Žofie plants (the water pits, the piles, the degassing drills and the liquidated main mine works and old mines).
