ABSTRACT

With the approaching accession to the European Union in 2004, the
Czech Republic has been working intensively not only on streamlining
legislative issues, but in particular on the unification of various processes in the
economic and industrial spheres. Ecology and the environment have, over the
past few years, become one of the Government’s policy priorities. The result is
a clear concept and future of Czech open cast coal mines. These are divided
into three separate companies from the point of view of their size and
significance, situated around the brown coal basin in the south-western part of
the Czech Republic, spreading over more than 100 km in length. These are
Severočeské doly, Mostecká uhelná společnost and Sokolovská uhelná. These
companies have applied primarily the concurrent continual mining method,
using technological aggregations. These consist of a central dispatch room,
long-distance conveyor belt systems with the material flowing from the
excavator on conveyor belts and then by dumpers and overburden dumping
machines or by caterpillar trucks.
The paper mentions in particular the experience with modernisation and
return on investments into systems for automatic process control of longdistance
conveyor belt transportation. Also described are the core functions of
the ZAT control system, used in the Czech Republic for controlling most
technological operations in open cast mines, and deployed successfully also in
Bulgaria – at Mini Marica Iztok.
