ABSTRACT

Hydrogeological features of the quaternary sediments lies in different assumption for
the emergence of freatic accumulations of groundwater and the ability to power or,
conversely, to some extent seal underlying aquifers. Effect of the opencast mining on
activities of quaternary sediments is significant and consists primarily in a drainage
effect. In places, where the overburden works crossed saturated parts of the quaternary
cover, there is a sudden drainage of aquifers. This water vents are regularly cause
unresponsive stability of the overburden and final slopes. The submitted paper follow
up by the available archival materials (methods and course of drainage, its
hydrogeological implications in space and time), comprehensive processing geology
(depositing, lithological characteristics) and hydrogeological conditions (hydraulic
parameters, water bearing strata, changes due to drainage, predict future developments,
water chemistry). The results of geological and hydrogeological analysis help us to
identify the areas that could pose risk for the extraction of mineral resources,
particularly of the brown coal.
