Development of technology for the rational integrated use of high-gas-bearing coal deposits and environmental protection from coal methane emissions
- Moscow Mining University
Abstract
More than 40 years ago, the main basins of the USSR began to carry out advance degassing of coal seams, extracting coalbed methane from the surface through wells. The basic technology is hydrodegasification of coal seams with subsequent extraction of water and gas. For high-gas-bearing coal seams occurring at depths of more than 500-600 m, the technology was improved by developing new ways of active impacts on the coal seam: physical, chemical, thermodynamic and a number of others. New technologies were developed: pneumatic separation, pneumothermal impact, hydrodistraction using gaseous nitrogen, cyclic hydrodistraction using liquefied nitrogen, etc., protected by patents and having no analogues in the world.
