【 摘 要 】

The article presents brief characteristics of the Kharbalakhs and Nadezhda deposits currently being mined. Exploration data on their specific structure, the variability of the geometric parameters of the seams, the statistical heterogeneity of the ash content in coal are reported. Frame and block models of the main coal seams are constructed based on the compiled database with use of mining and geological information systems. The paper considers a number of methods for interpolation of coal grade at different density of the exploration network. The spatial distribution of ash content in coal seams is mapped. The use of the obtained results can increase the validity of the decisions made at the planning, mining and coal preparation stages.
