Pilot Test on Blasting Crater in Deep Orebody of Anqing Copper Mine

Abstract

Abstract: In light of the characters of the No.2 orebody in Anqing Copper Mine and based on Livingston blasting crater theory and through the single-hole blasting crater tests on SK-Cu ore, Fe ore and Fe-Cu ore respectively, the optimal technical parameters of the blasting crater were obtained. On this basis, the optimal blasting parameters for the drilling-blasting of this orebody were also drawn, providing a precious basis for the future reduction of the drilling-blasting cost, improvement of the safe mining technology for gently inclined orebodies, the decrease of large fragmentation rate and the intensification of ore drawing.

Key words: Blasting crater, Industrial test, Blasting parameters, Blast-hole pattern
