Subject of the study are various research works which are carried out concerning issues of degassing, ventilation, management of gas release, etc. The following methods were used for the study: analysis, generalization, experimental works. Purpose is summarizing the experience of gas emission control in complex mining and geological conditions of mines in a number of Karaganda Basin (Republic of Kazakhstan) in the work of high-productivity mines, where the level of absolute gas content reaches very high values. In conclusion of the study it should be noted the experimental work with a total duration of 5 months in four faces at three mines of JSC "ArcelorMittal Temirtau" СD showed that the allowable methane content in the outgoing jets of faces and mine sections of 1.3% creates conditions for more rhythmic and uninterrupted operation of mine sections, compared with the limit methane content of 1.0%. The use of this modern high-precision system allows continuous quality control of the mine's atmosphere and promptly and automatically cut off electricity in areas with high methane content or violations of the ventilation mode (reduction of air supply).
