【 摘 要 】

For effective application of the method of analogy in the geometrization and prediction of indicators, it is necessary to observe the principle of similarity of the field being studied to the field-analog developed by the development. Under the conditions of similarity, it can be assumed that the nature and intensity of deformation of rocks in the conduct of mining operations will be about the same. When choosing a mine-analogue should be based on the coincidence of the degree of metamorphism of coal and rock epigenesis, tectonic structure of the sites, the lithological and material composition of rocks and their physical and mechanical properties, power and depth of the coal seam, hydrogeological conditions. Homogeneous areas of the deposit can be distinguished by various methods of cluster analysis. The quality of the classification is assessed by comparing the average values of indicators in individual clusters (homogeneous areas) with their average values throughout the place.
