Abstract: Few domenic people discuss about properties of underground mining of metal mines.According to the different characteristics of the ore deposit condition and ore-rocks physical mechanics that determined the metal deposits can't be standardized design in underground mining of metal mines,mean while,the parameters of mining methods mainly rely on the experience to determine,so this paper obtains the conclusion of the metal ore deposit underground mining has the technology characteristic and it belongs to the technology attribute.For the properties identified,the article also gives the way how to master metal deposits underground mining.
