Vrtanje vrtin za spremljanje nivojev vode v vodonosnikih na območju Premogovnika Velenje – izdelava vrtine PT-24a/2017

Kotnik, Gašper (avtor), Vukelić, Željko (mentor), Šporin, Jurij (komentor)

Namen diplomske naloge je predstaviti, kako se na Premogovniku Velenje spopadajo s hidrogeološko problematiko povezano z eksploatacijo premoga. V prvem delu diplomske naloge sem opisal geologijo območja Velenjske kotline in njeno hidrogeologijo v povezavi z odkopavanjem premoga. Natančneje so opisani trije vodonosniki, na katerih je posvečeno največ pozornosti glede odvodnjevalnih aktivnosti. To so vodonosnik v krovninskem delu, ki se podrobneje deli še na tri dele, triadni in vodonosnik v litotamijskem apnencu. V drugem delu diplomske naloge sem natančneje opisal vrste piezometričnih vrtin, s katerimi operirajo na PV in opremo, potrebno za izvedbo meritev nivoja podzemnih vod. Predstavljena je mreža piezometričnih vrtin na aktivnem območju odkopavanja premoga. V zadnjem delu diplomske naloge sem natančneje opisal izdelavo piezometrične vrtine Pt24a/17, ki je bila izdelana zaradi okvare piezometra Pt24/83. Predstavljene so osnove zakonov, katere je bilo potrebno upoštevati pri izdelavi vrtine in postopek tehnične izdelave piezometrične vrtine. Podana je priloga prereza vrtine in geološka zgradba območja na katerem je bila izdelana vrtina

Izvleček

The aim of the thesis is to describe how the Velenje Coal Mine deals with hydrogeological issues related to coil exploitation. In the first part of the thesis, I described the geology of the Velenje basin and how its hydrogeology relates to coal excavation. Three aquifers that get the most attention related to dewatering are described in detail. These aquifers are: aquifer above coal layer, which is further divided into three parts, triassic and aquifer in litotamnic limestone. In the second part of the thesis, I described piezometric well classes, which are used in the Velenje Coal Mine, as well as the necessary equipment for measuring underwater levels. The piezometric well network, which is in active exploitation area, is also described. In the last part of the thesis, I described how piezometric well Pt24a/17 was built due to the Pt24/83 piezometer breakdown. The laws that comply with the borehole construction are also described, as well as the technical procedure of the piezometric borehole construction. The borehole section and the geological structure of the area in which borehole was constructed is included in the appendix.
