Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of the study is the ventilation of the blind workings of the State Enterprise Coal company "Krasnolimanskaya". The purpose of the work is to develop recommendations for ensuring gas safety when releasing the outgoing air stream from the dead-end production of an air supply walker slope No. 1 in the overflow section of the l3 formation into the ventilation stream of air entering the production of 1 bis from the northern discharge section of the l3 formation. Research methods - generalization and analysis of results, methods of mathematical statistics, calculations using standard methods. As a result of the work, the technical documentation on airing the dead-end production of an air-supplying slant No. 1 of the drop-over part of the l3 stratum of the State Enterprise Coal company "Krasnolimanskaya" management team was analyzed. Developed "Recommendations for ensuring dust and gas safety of works on coal mining in 1" bis "northern lava of slope No. 1 in the overflow zone of the l3 reservoir, conducting a dead-end production of the ventilation drift 1 of the southern lava of the slope No. 1 in the overburden part of the l3 reservoir and ventilation of the stub part of the slope No. 1 of the outburst portion layer l3 with the release into the fresh stream of air entering their airing, outgoing ventilation jets of air from the dead-end part of the air supplying slope No. 1 of the drop-flow part of the layer l3 ". The release of an outgoing ventilation air stream from the dead end part of the air supply walker slope No. 1 from the overburden part of the formation l3 to the ventilation stream of fresh air supplied to the ventilation of the excavation section 1 bis of the northern lava of the downward slope No. 1 from the dropout part of the formation l3, deadlock development of the ventilation slope 1 southern lava has been agreed slope No. 1 of the overblown part of the formation l3 and dead end part of the downhill No. 1 of the fallout part of the reservoir l Product Description popup.authors popup.nrat_date 2020-04-02 Close
