Actualities and Application Prospect of the Low Dilution Ore Drawing Technology

Hu Xinbao(Maanshan Institute of Mining Research)  
The problems in the current cut off grade drawing technology are analysed and the advantages and disadvantages of the low dilution drawing,cut off grade drawing and no dilution drawing technologies compared.The application of low dilution drawing in China's mines is summaried and it is considered as an efficient way to reduce the dilution rate in nonpillar mining.The points of attention in its application in mining production are pointed out.
