Application of Pillarless Sublevel Caving Stoping Method in Inclined Medium Thick Orebody in Nalin Gold Mine

Abstract

Abstract: The experimental investigation of the pillarless sublevel caving mining method is introduced in detail in Nalin Gold Mine.According to the occurrence features of ore-body，the pillarless sublevel caving mining method was adopted to explore the inclined medium thick ore-body.Good economic benefits were obtained after application and practice for a period of time.It chose the sublevel of 676 m~684 m within the middle section of 660 m and the exploration lines between 14 and 20 as the experimental stope with industrial reserves of 22 778 t.In experiments，the mining loss and dilution rates were 23.65% and 18.18% respectively.

Key words: Gold mine, Pillarless sublevel caving stoping method, Medium thick ore body, Medium-length hole
