Varieties
- A furnel for descent of rock into the lower transport adit (vertical soil descent) [1] . At the bottom of such furnaces, a receiving hopper for the rock is created [2] .
- Furnishing for supplying materials to the upper adit [1] . This kind of furnishing is equipped with a mechanical lift [1] .
- Furnishing for the movement of workers (vertical walker ) [1] . To facilitate movement, the furniture is equipped with a ladder or steel brackets [1] . Large section furnaces can be equipped with single-cant hoists [2] .
