activities, standards and habits of citizens,<br />

as well as the availability of energy resources<br />

and economic - energy conditions<br />

in the environment.<br />

Because of known circumstances in<br />

the past, Serbia is an example of the country,<br />

which is forced in the short term to<br />

harmonize not only energy development<br />

with the business economic development,<br />

but development of energy production<br />

sector with the sectors of energy consumption<br />

in order to achieve higher levels<br />

of socio-economic development. Oil<br />

shales, a few years ago, fell in the "unconventional"<br />

fossil fuels, and are of worldwide<br />

very little explored.<br />

Interest in oil shale and testing capabilities<br />

their use in our country dates back<br />

to before the I World War. After the War,<br />

research was done on several occasions,<br />

but not systematically, so it has not been<br />

carried out to the end.<br />

OIL SHALE IN SERBIA<br />

Site researches of oil shale in Serbia<br />

are very small. On the territory of Serbia<br />

oil shale sites were discovered in the following<br />

regions: Niš (the Aleksinac Basin,<br />

regions village Bovan and Prugovac,<br />

Bubušnica and Kosanica Basin), Zaječar<br />

(Timok zone between Knjaževac and Boljevac),<br />

South Moravic (the Vranje basin),<br />

Kraljevo (the Kruševac and Čačak-<br />

Kraljevo basin) and Podrinje - Kolubara<br />

(the Valjevo-Mionica basin).<br />

Today, only for the oil shale deposit<br />

around Aleksinac we can say it is better<br />

researched than others, thanks to investigative<br />

work that are undertaken for the<br />

production of coal, and thereby collected<br />

data on oil shale, on the basis of prospecting<br />

the drillholes. However, even these<br />

data are not sufficient for final evaluation<br />

and exploitation of geological reserves<br />

and their categori<strong>za</strong>tion.<br />

Reserves of oil shale in Serbia, according<br />

to estimates, are approximately 8-10<br />

billion tons, where the Aleksinac deposit<br />

is the most researched. Large reserves of<br />

coal in our country are not available due<br />

to the economic or technical reasons.<br />

Proven coal reserves that are not suitable<br />

for surface exploitation amounts exceeding<br />

500 million tons, and oil shale are only<br />

in the Aleksinac deposit, over 2 billion<br />

tons. [1]<br />

AIM OF RESEARCH<br />

For the currently known oil shale reserves<br />

in our country, put us to the task to<br />

determine what is the energy and raw potential,<br />

with which we can count on a certain<br />

level of current technological reserves,<br />

especially those to be expected in<br />

the future.<br />

In order to elaborate the possibility for<br />

industrial use of oil shales while bearing<br />

in mind the fact that our country has a<br />

considerable oil shale reserves, and that<br />

the coal reserves in our mining – the energy<br />

plant ''Kolubara" and "Kostolac" limited,<br />

made the possibility of simultaneous<br />

analysis of coal and oil shale from the<br />

Aleksinac basin.<br />

RESEARCH AREA<br />

The Aleksinac deposit of brown coal<br />

and oil shale overtakes the area between<br />

the River Morava and the South Moravica<br />

offers directly from the town of Aleksinac,<br />

in the direction of NNW, the length of 10<br />

km and covers the area of about 20 km 2 .<br />

It is one of the few in the world, where<br />

the layers of oil shale stored together with<br />

brown coal, in floor and overlie main coal<br />

layer. In 1883, the exploitation of brown<br />

coal was dominated by the combined,<br />

room-pillar mining methods. Depending<br />

on the mining-geological conditions of<br />
