Methodical aspects of estimation of the influence of geomechanical states of coal-bearing massifs on their filtration characteristics

Article preview

The article summarizes the main factors that should be taken into account when developing a methodology to take into account the relationship between the geomechanical state of the rock formation and its filtration properties. The main approaches to solving such problems and their disadvantages are analyzed. The results of the research allow us to establish a functional relationship between the deformation-stress state of the rock formation and its gas permeability. The relationship is based on the analysis of volumetric deformation of the formation and its influence on the filtration characteristics of the medium.

Justification of rational methods of opening and mining of IV horizon in conditions of Starobinskoe potassium salt deposit

Article preview

The article presents methodological approaches to justification of rational development and mining of a new potash horizon. The state of ore mines of Belaruskali, geological conditions of IV potash horizon, main aspects concerning geomechanical justification of development parameters are considered. Based on the analysis of the stress and deformation state of rock strata recommendations for the development of IV potash horizon at the Third mine ("Belaruskali") are given.
