Information × Registration Number 0219U101169, 0118U007661 , R & D reports Title To conduct research on the sources of methane emissions, to develop recommendations and to adjust the speed of the air jet in the 1st "bis" to the northern bench slope No.1 of the drain section of the reservoir l3, equipped with a mechanized complex of up to 6 m / ms, and recommendations for the preparation and development of the 10 south lava slope number 1 "bis" of the formation k5 popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 14-05-2019 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2 As a result of the work, the technical documentation for working out 1 "bis" of northern lava of slope No. 1 in the dump part of reservoir l3 and 10 of southern lava of slope No. 1 "bis" of layer k5 of the II stage of the State Enterprise Coal company "Krasnolimanskaya" has been analyzed. Developed "Recommendations for the provision of safe working conditions when developing 1" bis "of the northern lava of the slope No. 1 of the dump part of the l3 reservoir Society with additional responsibility "Krasnolimanskoye" with air velocity in the clearing working up to 6.0 m / s." k5 10 coal seam southern slope of slope No. 1 “bis” of Society with additional responsibility "Krasnolimanskoye" without refreshing the outgoing air flow ”,“ Recommendations for ensuring gas safety of a high-loaded excavation section 10 of the southern slope of slope No. 1 “bis” of level k5 stratum Society with additional responsibility "Krasnolimanskoye" when using a returnable ventilation scheme, type 1-M ". The following were agreed: testing 1 “bis” of the northern lava of slope No. 1 in the dump part of the formation l3 at the speed of air movement in the clearing making up to 6 m / s; working out 10 southern lava slope No. 1 "bis" of the k5 stratum of the II stage without refreshing the outgoing air stream; the use of a return-flow type 1-M airing scheme of a high-loaded (more than 1000 t / day) excavation section 10 of the southern lava of the slope No. 1 "bis" of the second-level k5 stratum, and the calculation of the air flow necessary for airing it provided gas safety. The results of the implementation of the development - the application of the developed recommendations helped to ensure gas safety in mining, which is of great socio-economic and environmental importance.
