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.

The production activity of the coal mining industry is accompanied by the involvement in the development of deposits, which are characterized by a complication of mining and geological conditions at a depth of 1500 m. The increase in mountain pressure at great depths leads to a decrease in the efficiency of the use of complex mechanized technologies of coal mining. This is due to the imperfection of the technologies of fastening and control of mountain pressure. The existing schemes of movement of mechanized supports were developed for use at depths up to 800 m and do not take into account the features of geomechanical processes in the rock mass at depths of more than 800 m. In addition, the known technologies of fastening and management of the roof do not provide the necessary speed of fastening of the treatment face at high speeds of moving longwalls, thereby causing the formation of large undefended areas of the direct roof and increasing the probability of dumping in the bottom-hole space of longwall.

Показано, как на основе взаимосвязи деформаций слоев массива горных пород и образования в них техногенных нормальносекущих слой трещин осуществляется мониторинг за развитием зоны водопроводящих трещин над горной выработкой и прогноз ширины раскрытия техногенных нормальносекущих трещин в слоях подрабатываемого массива. Такой подход расширяет диапазон горногеологических условий, для которых решаются задачи безопасного ведения горных работ под водными объектами. It is shown how, based on the relationship between the deformations of the layers of the rock massif and the formation of technogenic vertically secant cracks in them, the changes in the parameters of the zone of water conducting cracks over the mine are monitored. Magnitudes of the disclosure of technogenic vertically secant cracks in the layers of the massif is predicted using the aforementioned relationship of deformations and crack formation. This approach expands the range of geological conditions for which the tasks of safe mining under water bodies are solved.
