SLIDE 2 In Polish coal industry the post-mining waste dumps are
stored at the area of over 4000 ha in more than 250
- bjects. The Central Statistic Office of Poland reports that
- n the coal mining waste dumps there are disposed 762,8
millions Mg of wastes from hard coal mining, what represents 51% of all stored industrial wastes in Poland. According to various sources, it is estimated that for each 1 Mg of coal produced, there is 0,4 – 0,5 Mg of waste
- material. This material has to be deposited in the coal
mining dumps.
Introduction
SLIDE 3
The production of hard coal in Poland in 2012 counted 79,2 million Mg. This allows to estimate that approximately 31,68 – 39,6 million Mg of waste material was produced in the year as well. In the past, due to the poor coal preparation technology the majority of this waste material was stored in coal mining waste dumps

Coal mining waste dumps in USCB
According to the literature study in the Upper Silesian Coal Basin there are ca. 220 coal-mining waste dumps, covering over 4000 ha. The highest concentration of the dumps occurs in the central part of USCB e.g. in Zabrze (34 dumps), Jaworzno (26) Bytom (21 dumps), Ruda Śląska (12 dumps) and as well as in the south-western part of USCB e.g. Rybnik (13 dumps) and Jastrzebie- Zdroj and surroundings (9 dumps). The largest dumps cover the area of over 250 ha (e.g. Central Coal Mining Dumps in Knurów).

SLIDE 11 Coal mining waste dumps in LSCB
According to the literature study in the Lower Silesian Coal Basin there are 39 coal-mining waste dumps. The majority of the dumps (23) has volume of dozen – several thousands of m3. Total surface of coal mining waste dumps covers ca. 305 ha, the volume reaches 65 millions m3. The height
- f waste dumps changes in the range of 3 do 105 m.
The largest waste dump in Wałbrzych area reaches 50 ha.
