Tech/Engineering - Mining & Minerals / Gems / Realizzazione di un pozzo
Italian term or phrase: contorno di scavo
Dopo aver discusso i risultati dell�analisi numerica di riferimento (caverna02), si commentano per confronto i risultati dello studio parametrico effettuato suddividendo, come detto, le analisi in 4 gruppi a seconda del parametro singolarmente indagato.
ANALISI DI RIFERIMENTO � CAVERNA02
� La superficie caratterizzata da coefficiente di sicurezza SF=1 separa le regioni dello spazio in condizioni elastiche (SF>1) da quella in condizioni di plasticizzazione (SF<1) individuando l�estensione della fascia plastica al contorno di scavo. La figura sottostante mostra che la plasticizzazione al contorno della caverna non supera generalmente i 2.0 m, ad eccezione della zona di passaggio dal fondo della galleria superiore al pozzo verticale, dove invece si forma un prisma di grandi dimensioni (circa 6.0 x 12.0 m), che non crea alcun problema alla galleria superiore mentre pu� essere pericoloso per il pozzo verticale. Durante la realizzazione del pozzo, infatti, il prisma di roccia plasticizzato potrebbe instabilizzarsi scorrendo ad esempio lungo un piano; per evitare che ci� accada � necessario prevedere un intervento di chiodatura sia sul fondo della galleria superiore che radialmente al contorno del pozzo.

around the excavation
Explanation:
in order to prevent this from happening rock bolts must be inserted into the upper part of the face of the tunnel and radially around the shaft
per evitare che ci� accada � necessario prevedere un intervento di chiodatura sia sul fondo della galleria superiore che radialmente al contorno del pozzo.

identifying the extent of the plastic ring of ground around the excavation.
individuando l�estensione della fascia plastica al contorno di scavo.

This ring of ground, is ground that has been loosened and has become "plastic" (not elastic), which means that it won't hold its shape, if you breathe on it, it might just fall on top of you.
