Development of Mining Processes with Regard of Limits Correction

Abstract

The Bílina surface quarry belongs to the largest brown coal mining company in the Czech Republic, Severočeské doly a.s. Mining activities within the POPD quarry Bílina take place in the territory of this quarry for the period of years 2010 to 2030. For a smooth, safe and economical process of the whole quarry in new territorial ecological limits, the process of overburden cuts needs to be extended as soon as possible to the south to the limit of new mining limits. However, this extension is limited by the current line of valid POPD. For the continuation of mining in the territorial ecological limits pursuant to the Resolution of the Government of the Czech Republic No. 827/2015, which is entirely in accordance with §30, par. a) of the Mining Act No. 44/1988 Coll., ie when using reserved deposits it is necessary, in particular, to extract the reserves of the reserved deposit as completely as possible, with the least possible losses and pollution. It is necessary to have a new POPD based on mining - technological procedures of OPV DB (Mining to new territorial environmental limits by 2035) approved by 2021 at the latest. However, these procedures will require a more complex methodology, because it will be necessary to mine in places, which could not be extracted within a valid POPD. Another intention is also to prolong the life of the quarry, and securing supplies to heating plants, power plants ČEZ a.s. (joint-stock company), as well as supplying quality low-sulfur brown coal to small customers throughout the Czech Republic.
