On the Mining Technology of Complex Orebody in Jianfengpo Tin Mine

The structure of exploitation in Jianfengpo Tin Mine now has mild slopes ranging between 3 ° ~6°. The mine contains a multi-metal mineral deposit which has the characteristics of the thin ore body and the com-plex structure.Jianfengpo mine has optimized the mining method and adopted the mining methods of full –ex-ploiting and full-loading, full-exploiting and partial-loading, and partial-exploiting and partial-loading on the basis of Shrinkage -breasting method so as to reduce the impoverishment rate in mining.This article mainly probes into the techniques of the comprehensive recovery mining in ore body with thickness between 0.4~1.8 m, especially introduces the method of partial-exploiting and partial-loading.
