CHINA MINE ENGINEERING

By taking the Meilingnan Copper Mine in Hami City, Xinjiang as the research object, this paper has built a three-dimensional ore body model of the mining area with the help of 3DMine software; built a variogram structure model after a combination analysis and transformation of the sample data based on the principles of geostatistics; used the distance inverse power method and the block model to divide the deposit into blocks for accurate resource estimation, analyzed the estimation results, drew the trend curve of the grade of the ore body in different directions and used it to verify and evaluate the model. The results show that the model built using 3DMine software is reliable and has a high estimation accuracy, providing a reliable basis for the design of medium and deep holes in mines.
