Purpose of research - development theoretical bases of formation of zones displacement and its activation as technical genesis of gas headers at an underground deep mining. Methods of research - analytical solution of problems and mathematical modeling. Were elaborated the theories of displacement of rock mass and ground surface, which allow to forecast the geometrical parameters of methane headers in rock's underworking on the mine fields of Donbass, and to come to decision for protection of object of underworking.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
