Hydorgeologıcal Conditions of The Coal Basın of Kosova Coal Deposit of Sibovci

Abstract

The coal basin of Kosova has a huge coal reserves, they are the main power sources for thermo power stations of Kosova. At
14.700Mt, Kosova possesses the world’s fifth-largest proven reserves of lignite [1]. The lignite is distributed across the Kosova,
Dukagjini and Drenica Basins, although mining has so far been restricted to the Kosova Basin [2]. The first systematic records
of lignite exploitation since 1922, when a small-scale, shallow underground room-and-pillar mining commenced in the Kosova
Basin.This case of study presents the hydrogeological conditions of the coalfield Sibovc, which is a part of coal basin of Kosova. The
study of the natural hydrogeological conditions and the relation of the coalfield with the flow of Sitnica River, are one of the basic
elements for the normal exploitation of the coal reserves (Figure 1). For studying of the hydrogeolocial parameters in this field close
the river Sitnica four wells have been drilled, which are used for testing and monitoring of the groundwater level. From testing
of these wells we have these hydrogeological parameters: porosity 20%, filtration coefficient 3.27 x 10-3 (m/s) and specific water
flow 2.54 (l/s). The gained results will be useful to avoid the flooding of the coal deposit by surface and groundwater from the river
Sitnica that flows close to the mine. Further development of lignite mining in the medium term will continue with exploitation of
the Sibovc field in the northern part of the Kosova Basin.
