【 摘 要 】

According to the results of the pilot trials in mines of Vostoktsvetmet, the combination shotcrete lining ensures stability and safety of underground excavation in complicated ground conditions. The paper presents the information on the conformity of the shotcrete mixture components to the standards. The compositions for the wet-mix shotcreting are selected. It is shown that inert materials used in the compositions have considerable influence on the properties of shotcrete mixes and shotcrete linings. The cost per unit of basic process materials (mixture components) is calculated in terms of Orlov Mine.
