Odvodnění kolektoru podložních písků lomu Vršany v letech 2011 – 2015

Abstract

The thesis summarises draining solution for the Vršany-J.Šverma (Vršanská uhelná a.s.) mine up to 2010. The main subject of this thesis concerns the draining of the most problematic section of the quarry, where the collector of wet underlying sands extends to the mining area. The foot of the coal seam in this area is positioned approximately 20 m below the former level of the collector. The thesis also includes a proposal for the draining of the underlying wet sands up to 2015, taking into account the progression of mining sections and internal quarry dumps. The thesis concludes with a general overview of cost evaluation of the draining for the whole quarry, and outlines the expenditure necessary to drain the underlying collector within the specified period.
