PRIJEDLOG ZA IZGRADNJU STALNE PODGRADE U UVJETIMA VELIKIH JAMSKIH PRITISAKA
Journal Title: UNKNOWN - Year 1989, Vol 1, Issue 1
Abstract
Prilikom izrade hodnika u rudniku lignita Titovo Velenje, u uvjetima velikih jamskih pritisaka, pri-mjenjeno je 12 različitih tehnologija. Prostorija prolazi uglavnom kroz laporovite gline i tufove s uloš-cima pješčenjaka. Većina primijenjenih tehnologija izrade, naročito u područjima izrazitih pritisaka, nije dala zadovoljavajuće 'rezultate u pogledu ostvarene dinamike radova, održavanja stabilnosti i projektiranog svijetlog profila prostorije. Analizom provedenih tehnologija izrade i jamskili pritisaka daje se podloga za izgradnju stalne podgrade koja se principijelno razlikuje od klasičnih jakih nepopustljivih podgrada. Karakteristike zamišljene podgrade, u uvjetima velikih jamskih pritisaka, omogućuju izgradnju prostorije u punom profilu, održavanje planirane dinamike radova, stabilnost i sigurnost prostorije, te se smanjuje cijena koštanja izgrađenog metra prostorije.
