CORRECTION OF EXPLOSIVE RATIO WITH ALLOWANCE FOR APATITE-NEPHELINE ORES FLOODING

The paper presents the differences in character of the blasting destruction of flooded and with natural water content apatite-nepheline ores. Correction factor on flooding for the explosive ratio calculation has been defined. Dependence of explosive ratio in the flooded conditions from the content P2O5 in the ore has been established. Variant of standard blasting project correction at the open pit has been proposed.

Keywords

Flooding, apatite-nepheline ores, explosive ratio, overgrinding radius, new surface, middle prill, КUZ-RAM model.
