закрит миньорски способ за прокопаване и укрепване на (основен) тунел
Explanation:
Howstuffworks "Tunnel Construction: Soft Ground and Hard Rock"
The second technique, shown in the diagram below, is the top-heading-and-bench method. In this technique, workers dig a smaller tunnel known as a heading. Once the top heading has advanced some distance into the rock, workers begin excavating immediately below the floor of the top heading; this is a bench. One advantage of the top-heading-and-bench method is that engineers can use the heading tunnel to gauge the stability of the rock before moving forward with the project.

Reference: в мултитран

Reference information:
е посочен следният термин на руски :"передовой верхний забой при разработке тоннеля уступами". Не смея да го превеждам, защото ще е буквално, а си нямам понятие за какво прокопаване става дума, на стъпала ли, на площадки ли някакви.

В Английско-български минен речник намирам: top heading пилотираща галерия в калотата. Освен това benching: 1. стъпално изземване, добив със стъпалообразен забой ...

Ами речникът е писан от известен специалист, когото не си позволявам да коментирам. Аз съм "жичкаджия".

Asker: Мисля, че това би било най-добрия отговор по отношение на терминологията в минното инженерство.
