Research on Mining Technology of Steeply Inclined Thin Ore Body in High-grade Content Mine

Abstract

Abstract In view of the problems of poor mining safety, low recovery efficiency, high cost, low recovery rate and few recovery options in steeply inclined, extremely unstable thin to medium-thick ore bodies, especially there are no economically feasible mining options for low-grade resources of this type of deposit Difficult problem. The paper proposes a safe, high-efficiency and low-cost mining technology suitable for steeply inclined thin ore bodies-segmented empty field subsequent filling mining method combined with 3Dmine and ANSYS to establish a FLAC3D numerical model to obtain a stope production capacity of 180t/d and a loss rate of 7.40%, the expected effect of the dilution rate of 14.96%.
