DISPATCHER CONTROL OF TECHNOLOGICAL AGGREGATIONS IN OPEN CAST MINES

V. Karpisek

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 Severo\vcesk\'e doly, Mosteck\'a uheln\'a spole\vcnost and Sokolovsk\'a uheln\'a. 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.
