ABSTRACT
Influence of fine gridding cementing material on backfill strength and quality of mined ore around artificial rock massif is described. Economical evaluation of fine gridding technology of cementing material depending on backfill compound, required gridding fineness and cost of materials is carried out. Expedience of fine grinding technology usage taking into account technological and economical factors is justified.
