Abstract: The common problems existing in the exploitation of flat-dipping thin ore-bodies are that the production capacity is lower and the recovery is difficult.Through developing the inclined well and adopting belt hoisting，continuous ore-drawing at medium belt transport，and sub-section advancing mining process，no  or less pillar remained，the continuous recovery can be realized.The working width should be controlled to maximize the ore recovery and reduce the dilution so as to effectively solve the problems in mining and transportation.This method can provide a new idea for the efficient exploitation of thin ore-body，and the research results play an important role in high efficient mining of thin mineral veins.

Key words: Gentle inclination, Thin mineral veins, Sub-section advancing, Continuous ore-drawing
