CHINA MINE ENGINEERING

The copper orebody in Yinshan Mine is mainly composed of finely veined and disseminated ores. The shape, occurrence, thickness, grade and other geological characteristics of the orebody varies along its strike and dip direction. To verify the applicability and reliability of the method, technology and grid used in the recent exploration work, a production exploration was carried out based on the recent exploration by densifying the exploration grid, and the geological characteristic parameters obtained were compared with the geological exploration outcomes. The comparison results show that the exploration method is applicable, the quality is reliable, and the characteristics of the orebody has certain change after the exploration grid is densified; exploration management and comprehensive research should be further strengthened in actual mining process.
