PROBLEMS AND PROSPECTS OF COAL MINE METHANE
The use of coal mine methane ensures the implementation of the principle of integrated development of the deposit. The urgency of the problem of coal mine methane is determined by the fact that the Presidential Decree of September 30, 2013 № 752 "On the reduction of greenhouse gas emissions" is to bring to the 2020 decrease in emissions. The article substantiates the necessity of cardinal growth of the volumes of utilization of mine methane, as well as the strengthening of the role of degassing methods. The main reasons for the low level of utilization in the Russian Federation are noted. The main directions of using coal mine methane at present are considered, among which are: heat generation (fuel in boilers and other heat generators); generation of electricity (fuel for diesel engines of alternators); fuel for motor vehicles; raw materials for the chemical industry. The analysis of the main methods of utilization of methane-air mixtures is presented. Three perspective technologies for recycling methane from the ventilation streams of coal mines to the atmosphere are singled out: a thermal reactor with reversible flows "VOCSIDIZER", developed by MEGTEC Systems; a thermal reactor with reversible flows "VAMOX", developed by the company "Biothermica Technologies Inc."; a catalytic reversible reactor developed by Canadian Mineral and Energy Technologies. International practice shows that the implementation of projects for the utilization of coal mine methane, as a rule, requires the economic stimulation of such works. The article gives the main incentives and identifies the main directions for solving the problem of coal mine methane utilization.
