Abstract
The necessity of development of new principles of approach to organization of degasification works at coal mines and directions of improvement of technological schemes at development of high-gas-bearing coal seams at great depths is grounded. The technological scheme of working out of a mining area with a direct flow ventilation scheme, with isolation of excavated space and protection of preparatory workings with cast strips from quick-hardening materials is offered.
