Coal mining

How coal is mined in OKD

The mining company OKD, a. s. is the only producer of hard coal in the Czech Republic; its coal is mined in the southern part of the Upper-Silesian coal basin.

All OKD mines are deep mines and coal is exploited using shafts and adit system - nowadays exclusively by means of mechanized processes and modern technology. Deep mining is carried out under intricate geological conditions in a series of strata reaching many hundreds of meters deep. The coal is of Paleozoic (carboniferous) age and is exploited from the coal-bearing strata series in the Ostrava and Karviná region. The thickness of the Ostrava seams deposited deeper (exploited by Mine 3 – former Paskov Mine and Mine 1 – former Karviná Mine - Lazy Site) is between 0.8 and 1.5 m. The thickness of seams in the Karviná region is between 1 and 6.5 meters.

Currently, mining is carried out in the active part of the district in area of 133.65 km2 in eight mining areas:

 

  1. Mining operation 1
    1. mining site ČSA
    2. mining site Lazy
    3. mining site Darkov
  2. Mining operation 2
    1. mining site North
    2. mining site South
  3. Mining operation 3
    1. mining site Staříč
    2. mining site Chlebovice
  4. The Frenštát Mine IOU
    (preservation mode)

 

Output coal is prepared at the washing plants of the individual mines and is divided according to quality parameters into coal suitable for coking and steam coal.
