Essay

The thesis concerns the problems of peculiarities of gas emission from worked out areas of faces exhausted. Another task is to solve the problem of gas bearing coal stratum safe working out when rock displacement takes place. There was carried out the analysis of modern points of view as for gas formation processes in coal deposits, and forms of methane appearance both in coal and rocks. There were determined conditions and reasons of gas emission from worked out areas of faces exhausted when rock displacement takes place. Model that perfectly combines gas emission into headings and degassing holes from the areas with different intensive rock conditions when mining is performed in two mutually perpendicular directions was developed. There was determined direct proportional dependence between gas emitted from worked out areas of faces exhausted and volumes of surface displacement ba-sins as a result of one more mining district working out. There were found out conditions of gas emission appearance and peculiarities under rock displacement to classify it as a separate (specific) type of methane emis-sion in coal mines.The methods of stoping airing and degassing under the conditions of rock dis-placement have been progressed. Method testing in mines has confirmed the efficiency of the work.
