THE MAIN PARTNER

The Mine and Thermal Electric Power Plant Gacko are located in Gacko energetic basin in the southeastern part of Republic of Srpska. Thermal electric power plant is a powerful and important thermal-energy production capacity with the annual production and delivery to a joint electric energy system in the amount of the effective 1.650.000.000 KWh of electric energy.The first stage of Thermal Electrical Power Plant, a block of 300 MW was commissioned on 09. February 1983.

Tehnological equipment of the main power plant are boiler and turbine with pump and ventilation plant manufactured in former Soviet Union. Generator is jointly produced by Rade Končar from Zagreb (stator) and Elektrosila from Sankt Petersburg (rotor).

Additional and supporting facilities of the Thermal Electrical Power Plant are: raw water supply system  for Thermal Electrical Power Plant with preparation of all technological waters for the work of boiler and plant, system of internal and external transportation of slag and ash with depots, system of supply and preparation of quantity of coal necessary for Thermal Electrical Power Plant, waste waters and technological system as well as the entire infrastructure.

GACKO COAL BASIN

Gacko coal basin is located in the Gacko field in the northeastern part of Herzegovina. It occupies about 40 km2 at the altitude of about 940 m, in a typical carst region. This region characterizes with very specific climate conditions with temperatures ranging from -30 to +370 C, with the average precipitation of 1.750 mm on an annual basis. This terrain is mostly plain. The basin is divided into four exploitation fields: Western exploitation field, Central exploitation field, Eastern exploitation field and Caprock coal zone.

First works on coal exploitation in Gacko began in 1954, on the outcrops of the main coal seam, while in 1982 the mine of lignit „Gračanica” was commissioned with the annual capacity of 1.800.000 tons of coal and 3.200.000 m3 of overburden in the area of the Western exploitation field. On the stripe mining „Gračanica” the continuous work technology was applied through which satisfying results were achieved in terms of production of overburden and coal, which, together with new balance reserve of 476.339.950 t, puts Gacko power system in row with the biggest such systems in Republic of Srpska, prompting continuous new explorations and investments in the development of the basin.

Coal reserve in Gacko are estimated to exceed 400.000.000 tons, while it is assumed that this reserve will have the work of two blocks of 300 MW power secured for the period of the next 100 years. The explorations showed that the Gacko coal is of the high quality and that it is profitable to be exploited. Recently, the technology of coal production has changed. Applying the newest scientifical researches, the trend is now strongly focused on the principle of selective excavation, which results in obtaining much cleaner coal on the depot and is without waste-rock. In the end it resulted in TE production of 280 MW, the number of delays has been decreased, while failures are more sparse.

Taking into account what has been explored up to now, today’s available resources of coal in the Gacko basin correspond to the heating potential of about 3.380.000 x106 kJ for surface exploitation, which secures the work of more thermo blocks.

GLAVNI PARTNER

Rudnik i Termoelektrana Gacko nalaze se u gatačkom energetskom bazenu u jugoistočnom dijelu Republike Srpske.

Termoelektrana je moćan i značajan termoenergetski proizvodni kapacitet sa godišnjom proizvodnjom i predajom u zajednički elektroenergetski sistem efektivnih 1.650.000.000 KWh električne energije.

Prva faza Termoelektrane, blok snage 300 MW pušten je u pogon 9. februara 1983. godine. Glavna oprema Rudnika i TE Gacko je :

· Kotao PP990-250 (P64) - Fabrika kotlova - Podoljsk

· Turbina LMZ-K-300-240 - Sankt Petersburg

· Generator 350MVA - Rade Končar - Zagreb

Tehnološka oprema glavnog pogonskog objekta su kotao i turbina sa pumpnim i ventilatorskim postrojenjem, sovjetske proizvodnje. Generator je zajedničko djelo Rada Končara iz Zagreba (stator) i Elektrosile iz Lenjingrada (rotor).

Prateći i pomoćni objekati termoelektrane su : sistem snadbijevanja sirovom vodom za TE i pripremom svih tehnoloških voda za rad kotla i postrojenja, sistem unutrašnjeg i vanjskog transporta šljake i pepela sa deponijama, sistem snadbijevanja i pripreme potrebnih količina uglja za TE, sistem otpadnih i tehnoloških voda i cjelokupnu infrastrukturu.

GATAČKI UGLJENI BASEN

Gatački ugljeni bazen je smješten u Gatačkom polju u sjeveroistočnom dijelu Hercegovine. Prostire se na površini od oko 40 km2 na nadmorskoj visini od oko 940 m, u tipičnom kraškom području. Područje se odlikuje veoma karakterističnim klimatskim uslovima, gdje se temperature kreću od -30 do +370 C, sa prosječnim atmosferskim padavinama od 1.750 mm godišnje. Teren je uglavnom ravničarski. Basen je podijeljen na četiri eksploataciona polja: Zapadno eksploataciono polje, Centralno eksploataciono polje, Istočno eksploataciono polje i Povlatna ugljena zona.

Prvi radovi na eksploataciji uglja u Gacku su počeli 1954. god. na izdancima glavnog ugljenog sloja, a 1982. god. je pušten u rad rudnik lignita "Gračanica" sa godišnjim kapacitetom od 1.800.000 tona uglja i 3.200.000 m3 otkrivke, na prostoru Zapadnog eksploatacionog polja. Na PK "Gračanica" je primijenjena kontinualna tehnologija rada kojom su postignuti zadovoljavajući rezultati na proizvodnji otkrivke i uglja,  što uz nove bilansne rezerve od 476.339.950 t, svrstava Gatački energetski basen u jedan od najvećih u Republici Srpskoj i nalaže da se stalno vrše nova istraživanja i ulaganja u razvoj basena.

Rezerve uglja u Gacku procjenjuju se na preko 400.000.000 tona, a smatra se da te rezerve obezbjeđuju rad dva bloka snage 300 MW za narednih 100 godina. Istraživanja su pokazala da je gatački ugalj viskog kvaliteta i da ga je isplativo eksploatisati. U poslednje vrijeme promjenila se tehnologija dobijanja uglja. Primjenjujući najnovija naučna istraživanja, maksimalno se ide na selektivno otkopavanje, pa je sada ugalj na deponiji dosta čistiji, bez jalovine. To je rezultiralo da proizvodnja termoelektrane 280 MW, smanjuje se broj zastoja i rjeđi su kvarovi.

Raspoloživi resursi uglja u Gatačkom basenu na današnjem stepenu istraženosti odgovaraju toplotnom potencijalu od oko 3.380.000 x106 kJ za površinsku eksploataciju, što obezbeđuje  rad više termoblokova.
