Abstract
To address the significant discrepancy between traditional reserve estimation methods and actual mining volumes,this study establishes the mining block method through fundamental principles,block division criteria,reserve estimation formulas,and key parameter analysis.Using the 21-2R orebody in the F2 lower bench(115～190 level)of Makeng Iron Mine as a case study,we employ horizontal and vertical projection methods for block division and reserve calculation based on geological exploration data,mining technology,and field measurements.Comparative validation with actual mining geological reserves demonstrates that the horizontal projection method estimates the 21-2R orebody's reserves at 154,100 tons,showing only a 1.03%relative error compared to the actual 155,700 tons.The mining section method,integrated with mining process layout tunneling,significantly improves reserve estimation accuracy,providing reliable geological data support for mine production decision-making.关键词
