The article states the main factors which have to be taken into account in designing highoutput cleaning complexes in conditions of the Vorkuta deposit. Basic approaches to solving this problem have been analyzed and the main problematic issues have been outlined. Research results are given, which help to establish functional dependence between the stress-and-strain state of the rock strata and its gas permeability basing on the analysis of the rock massif volumetric deformation and its impact on the filtration characteristics of the medium.
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.
Methodical approaches for substantiation of rational development and mining of new potash horizon are presented in the article. The state of ore mines of «Belaruskali», geological conditions of the IV potash horizon, main aspects concerning geomechanical substantiation of development parameters are reviewed. Recommendations on development of IV potash horizon at the Third mine («Belaruskali») are given on the basis of analysis of stress and strain state of the rock strata.
