TERRITORIALLY - ECOLOGICAL LIMITS AND THEIR IMPACT ON MINING ACTIVITIES IN LOCALITY DB, SD A. S.

Abstract

The lecture deals with the issue of newly approved territorial ecological limits. Mining - technical conditions of mining or mining - geological conditions together with the optimal choice of the concept of mining procedures predict the efficient and safe use and extraction of a reserved mineral deposit in a given mining area. The mining space must be determined and define on the basis of mining ? geological conditions of every mining location due to the application of all the principles contained in the Mining law No. 44/1988 Coll. The defined limits of mining activities have changed thanks to approval territorially ? ecological limits of coal mining, Resolution of the Government of the Czech Republic No. 827 of 19. October 2015. The boundaries of mining activities must be ? according to valid legislation ? at a distance of at least 500m far from built-up area of the municipality. This fact changes the existing intentions of the process of quarrying of coal bed in the area of southern slope. The final edge of the fracture must be formed further from the starting slope and thus mining will take place under different geotechnical conditions than previously assumed. The original intention of the quarry has been done more to the south, with the possibility of entire extraction of the coal reserves on a naturally inclined slope. The original solution enabled creating the final lines of the southern slopes up to underlying formation of rock zone. The change of the TEL represents for the Bilina Mines a certain loss of coal reserves due to leaving a permanent protective coal pillar on the southern edge of the coal basin. The setting up of the new TEL also includes the modification of the studies that were commissioned for the preparation of a new mining permit in the scope of the documentation "Opening, preparation and mining project at Bilina 2035".
