Technologies Used<br />
Overburden is extracted using KU 800 and SchRs 1550 excavators of the TC2 range. Overburden is<br />
transported by 1,800 mm gauge conveyor belt and deposited in spoil benches adjacent to the ZP 5500,<br />
6600 and ZPDH 6300 spreaders of the same series.<br />
In the coal quarry, we use KU 300S and K 800 excavators of the TC1 range. Coal is extracted by<br />
1,200 mm gauge conveyor belt and transported by 1,600 and 1,800 mm gauge conveyor belt<br />
to the Tušimice II Power Station or to a loading facility for the power stations Prunéřov I, Prunéřov II,<br />
and Chvaletice.<br />
A homogenization depot, through which most extracted coal passes, ensures consistent quality<br />
of coal extracted for supply to ČEZ power stations.<br />
Estimate of Economically Usable Stocks of Doly Nástup Tušimice<br />
At the end of <strong>2004</strong>, 320 million tonnes of usable stocks were available in the Tušimice mining area<br />
as set by the Most District Mining Authority on 9 August 1994.<br />
Doly Bílina<br />
In <strong>2004</strong>, Doly Bílina extracted 9.2 million tonnes of coal and 43.4 million m 3 of overburden.<br />
In the years to come, mining activity at Doly Bílina will continue at just two sites: the quarry itself<br />
and the external Pokrok overburden dumping area. The mining front is advancing in a parallel westerly<br />
direction.<br />
Bílina Quarry<br />
At an estimated <strong>annual</strong> coal extraction volume of 8.0–8.5 million tonnes, the Bílina Quarry mining<br />
operation in its current spatial figuration, given by environmental protection restrictions under<br />
Government Resolution No 444/1991, will be shut down between 2030 and 2035. Under a Decision<br />
of the Most District Mining Authority of 23 January <strong>2004</strong>, the mining operations of Doly Bílina are<br />
permitted in accordance with the approved Plan of Development, Preparation and Extraction<br />
for the period up to the end of 2010, or until such time as the permitted limits are reached.<br />
Overburden Disposal<br />
The bulk of extracted overburden is deposited at an internal spoil heap. Only overburden from the first<br />
overburden section is disposed of at the external Pokrok dumping area.
