ABSTRACT
For about 40 years the main coal mining regions of the former Soviet Union have been engaged in this scientific research. The basic technology is to hydraulically fracture coal beds with water and following this recovers gas and water. The depth of coal bed occurrence of more than 500-600 m requires a new technology of methane recovery from coal beds that are not distressed, based on active physical, chemical, thermodynamic and other effects, which are protected by Russian patents and have no analogies in the world practice.
