20.500.12556/DKUM-82078 Rekonstrukcija in izdelava tehnične dokumentacije povratne postaje jamske sedežnice v podjetju Premogovnik Velenje d.o.o. diplomsko delo univerzitetnega študijskega programa I. stopnje Reconstruction and development of tehnical documentation for the return station of the undergraund chairlift in the company Premogovnik Velenje d.o.o. V podjetju Premogovnik Velenje d.o.o. se z namenom hitrejšega prevažanja zaposlenih na delovišča uporablja namenski transportni sistem jamska sedežnica. Jamska sedežnica se nahaja v južnem krilu jame Preloge in je dolžine L = 630 metrov. Trenutno je na povratni postaji jamske sedežnice nameščen povratni kolut s – glede na pravilnik – premajhnim premerom – Pravilnik o zahtevah za zagotavljanje varnosti in zdravja pri delu in tehničnih ukrepih pri prevažanju v podzemnih prostorih in na površini pri raziskovanju in izkoriščanju mineralnih surovin UL RS 111/03 in61/10-ZRud-1. Zaradi premajhnega premera povratnega koluta prihaja do okvar na celotni trasi jamske sedežnice in s tem povečane obrabe vlečne jeklene vrvi. V podjetju so se odločili za rekonstrukcijo povratne postaje jamske sedežnice in povečanje povratnega koluta jamske sedežnice. V diplomskem delu je predstavljena rekonstrukcija povratne postaje in izdelani načrti, ki se bodo uporabili pri izdelavi nove postaje. Predvidevamo, da bomo z rekonstrukcijo zmanjšali število okvar na sedežnici in s tem zmanjšali obrabo jeklene vrvi. The company Premogovnik Velenje d.o.o. also uses a dedicated transport system known as cave chairlift, for faster transport of workers to work sites. The cave chairlift is located in the south wing of the Preloge Cave and is approximately L = 630 meters long. Currently, at the return station of the cave chairlift, there is a return reel with too small diameter according to the Rules on occupational safety and health requirements and technical measures for transport in underground premises and on the surface in the exploration and exploitation of mineral resources UL RS 111/03 in 61/10-ZRud-1. Due to the too small diameter of the return reel, the entire pit chairlift line is caused by failures and increased wear of the towing steel rope. The company decided to reconstruct the return station of the cave chairlift and enlargement of the return reel of the cave chairlift. The thesis contains the reconstruction of the return station and the construction of plans, which will be used in the construction of the new station. The reconstruction assumes that we will reduce the number of failures on the chairlift and also reduce the wear of the steel rope. jamska sedežnica povratna postaja povratni kolut rekonstrukcija pravilnik Cave chairlift return station return reel reconstruction rule book true true false [R.
