ABSTRACT

Kosovo has a considerable wealth of coal reserves, which is calculated to be over 14
billion tons. Conditions for exploitation of coal are good while the coal layer has a
thickness of about 60 meters. There is another 60-80 meters coverage area of coal in
Sibovc, in which is calculated to move the development of open-pit mine, due to the
completion of exploiting the current field, which is exploited by the Mirash and Bardh
fronts. Continual technology (excavators and belt conveyors) was used in both
exploitation fronts, starting in Mirash then in Bardh. After the 1998/99 war in Kosovo,
due to the coal needs and delay in overburden removal, we had to hire a German
company for overburden removal. This work was conducted by this company in 5
months, removing 5.5 mil/cubic of overburden. The entire activity was performed with
truck and shovel technique. This surprised us in positive way and led us to examine the
advantages and disadvantages of the truck and shovel technique. Since 1958, this
technique began to be used in our mines.
After the war, when I began working as a young engineer in this mine, I noticed the
weakness and success of truck and shovel technique around the world, especially in
America, Canada and Australia. These analyses made me believe that truck and shovel
technique has many advantages, particularly by the success that was achieved during the
5 month performance.
This result realized over 10 million tons, while with the continual technology that we
use now we realize about 8 million tons for 12 months. The company that used truck
and shovel technique had three times better results than we had using continual
technique. I want to point out that for this continual technique we had known German
open-pit mine consultants and experts, who had given their suggestions and estimates
for work in mining using available continual technology.
