Pingmei Group 6 is a large modern coal mine, since mine production, a large well field boundary changes, and has undergone 12 changes, the area also has 05 years of 12.7km2 and 06-year 19.3km2. Therefore,the six mine re-classification of reserves and eva luation is imperative. The papers through four mine coal bed contour maps and reserve calculation for digital and on the basis of the "coal resources geological exploration norms" and the coal production statute, "solid mineral resources / classification," and other relevant norms and bed contour map of the reserves classification and eva luation, through economic eva luation and comprehensive eva luation,6 mine have better profitability and a strong ability to resist risks, and coal reserves sufficient, reliable resources, the prospects for more extensive marketing, quality products and a favorable external conditions, resource utilization is very good, with strong market competitiveness. Normal for the pit production, a deployment and drawing up development plans for the extension of construction, expansion, technological innovation, and provide a reliable basis for the Integrated mining equipment models.
