Improvement of Support Technology in Artemevsk Mine of Vostoktsvetmet

Аннотация

The state of mining in Artemevsk Mine is analyzed, and the current and recommendable support designs are described. In unstable rock mass, it is possible to replace heavy and laborious steel frame support by less expensive and lower labor-intensive shotcrete lining with surface reinforcement without reduction in load-bearing capacity of the support. The variants of arrangement of shotcrete production plant are discussed, and the economic efficiency of the proposed wet-mix shotcreting is calculated in terms of Artemevsk Mine.
