摘要
Mining operation has been conducted recently in Tongken mine, focusing on No.92 lean orebody, while the thickness of the ore is reducing rapidly with irregular shape and more branches and composite parts. In order to improve the economic effectiveness, it is in urgent need to delineate the boundary of the orebody again and put it in control. After several years practice it proves that secondary delineation of the orebody boundary during mining operation at the district of lean ore and side ore is a very important way to achieve economic effectiveness for mining company as it effectively reduces the loss due to dilution.
