ABSTRACT

Drenica coal Tertiary basin is located in the mid of Kosovo coal basin in the east and
Dukagjini basin in the west.
Skenderaj coal deposit represents the northern more productive part of Drenica coal
basin. The deposit is explored by drillings. In total there were 42 drilling with 1790
meters in length, which provided good opportunity to study the deposit.
There are the various lithologic and stratigraphic units in Drenica Tertiary basin. The
western part of basin includes Cretaceous flysch represented by sands, clays, limestone
with sand and conglomerates. The east part, unlike the west part, is more homogenous.
Except flysch there are found and Paleozoic rocks (phyllite, crystallized limestone,
quartzites) and serpentinites.
Within Tertiary sediments in Skenderaj field are identified depositions, which belong to
Pontian age, in which three strata are separated. From bottom to top are: bottom strata,
coal seam and top strata (overburden).
Spatial analysis or spatial statistics includes a series of techniques for analyzing spatial
data. The initial procedure of analysis includes the set of generic methods of exploratory
analysis and the visualization of data, in general through maps. Software for application
of this spatial analysis requires access to characteristics: their location and their
attributes.
For variables such as top, bottom, thickness of coal seam, ratio coal/overburden,
calorific value, ash and sulfur content was created a set of maps (combination of post
map, contour map, 3D wire frame map and 3D surface map).
Spatial analysis of exploration drillings show that the overburden sediments have a
thickness in the interval 1.50 – 35.00 m. Coal seam has a variable thickness from 5.0 to
over 22.0 m, average about 15 m. Most of the coal seam has calorific value of 7117 –
7955 kJ/kg. In extreme cases reach maximum 9210 kJ/kg and minimum value 4186
kJ/kg.

The performed comparison shows a closed agreement between obtained results by
statistical methods.
