Shotcrete support . 7. Mesh reinforced shotcrete . While steel fibre reinforced shotcrete has been widely accepted in both civil and mining engineering, mesh reinforced shotcrete is still widely used and is preferred in some applications. In very poor quality, loose rock masses, where adhesion of the shotcrete

Shotcrete is an all-inclusive term for spraying concrete or mortar with either a dry or wet mix process. However, shotcrete may also sometimes be used (incorrectly) to distinguish wet-mix from the dry-mix method. The term shotcrete was first defined by the American Railway Engineers Association (AREA) in …

Ground Support & Underground. Earth and rock excavations are effectively stabilized with shotcrete and a variety of reinforcement and anchoring systems. Using shotcrete to stabilize soil for excavation has advantages over traditional timber and steel shoring techniques. Shotcrete is also ideal for ground support in tunneling and mining.

necessary ground support for a wide range of ground conditions. Current trends indicate that increasing numbers of metal mines are relying on shotcrete as an integral ground support component during the mining development cycle (5). According to Rispin et al. (2, 5), a mine has recently experimented with automated shotcrete equipment, using a ...

bolts and cables, and support, with shotcrete, mesh and steel sets which carry loads from individual rock blocks isolated by structural discontinuities or zones of loosened rock. These notes are intended to assist the underground support engineer in choosing the most appropriate, and the easiest to install, combination of reinforcement and support.

Each retaining wall needs to be engineered for the specific job conditions. It is fairly common, however, to see two layers of reinforcing bars in a wall of this thickness. In addition to reinforcing the wall, the steel would help support the shotcrete during placement. If drying shrinkage crack control is an issue, synthetic fibers may be added.

The logistics of shotcrete in underground mining Ground support with mechanized shotcreting abbreviates working cycles in underground mining, as it is applied faster than wire mesh. It can be applied in access ramps, caverns and other underground infrastructure, as well as in exploration and extraction galleries.
