Prefabricated mine. Elements of the ABETON mine support are designed for the construction of prefabricated manholes, mine shafts, sewage pumping stations and tanks from 4 to 50 m.

The structures are designed for soil pressure (watered sand) at a depth of 20 m and a pressure of 5 atm (when injecting mortar).

Mine shafts are assembled by bringing prefabricated reinforced concrete elements from below, followed by welding the ring to be assembled and the ring above it on the embedded parts. After assembling every two rings, the cavity between the outer surface of the shaft and the rock must be filled with mortar. Injection is carried out through special holes provided in each prefabricated element under a pressure of 5 atm.
