Abstract

The area of the CSA mine is situated at the northern edge in the central part of the Most Basin (North Bohemia, The Czech republic). The interesting area, currently represented by the internal wastedump and the own openpit mine CSA, has undergone significant changes over time that are associated almost with coal mining activities. This activity hit especially hydrological and hydrogeological conditions of the area. The original surface was naturally drained by the several streams, which were necessary translate to artificial flows due to the developing of coal mining. In the interesting area were located a considerable amount of natural reservoirs, the largest was lake Drinov (Komorany). The presented area is divided into several hydrogeological units, which are characterized by mutually diferent major determinants, such as morphology, lithological charakteristice of the main types of rocks, tectonic disorders etc. The submitted paper describes the changes in the hydrological and hydrogeological conditions in the interesting area that occur during the exploitation of brown coal deposit and their impact on the mining operations in the openpit mine CSA.
