The oredilution rate depends on the ore drawing parameters.
矿石贫化率取决于放矿参数。

This method can improve the ore extraction rate and reduce the oredilution rate and has been found to be a rational mining method for the mine.
该方法提高了矿石的回采率，降低了矿石的贫化率，为矿山寻找出一条合理的开采方法。

Research shows that main cause of oredilution in sublevel caving mining is tlnrational cut-off grade drawing. Non-dilutionore drawing is most ideal drawing mede.
