Abstract

This thesis addresses the aquifer drainage collectors interdeposit and underlying sands in coal mines Jan Šverma and Vršany. These collectors are saturated considerable obstacle to the smooth progress of brown coal. To drain respectively. reduce the level from the beginning of extraction using drainage / pumping wells. Currently, the greatest threat to the smooth progress of work for exploitation collector underlying sands, whose piezometric water level is around 20 m above the present day quarry. Due to the planned direction of the coal head, location of existing wells and drainage characteristics of the soil in the thesis proposed building two new gas wells in the area of ​​the collector underlying sands and three observation wells in the area of ​​the collector interdeposit sands including the design and fitting out their location within the mine.
