Information × Registration Number 0219U101192, 0118U007647 , R & D reports Title Development of measures for the release of the outgoing air jet from the reconnaissance sidewalk number 1 of the reservoir l1 and the reconnaissance sidewalk number 2 of the formation l1 to the northern rocks of the lava reservoir l1, in the mining and geological conditions of the Separated subdivision "Central Mine" of the State Enterprise "Mirnogadugol" popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 17-05-2019 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of the study is the airing of the excavation site of the Separated subdivision "Central Mine". The purpose of the work is to develop recommendations for ensuring the dust-gas safety of works on excavation of coal in the indigenous lava of the l1 stratum, when releasing air flowing to its airing to the fresh stream, outgoing ventilating air jets from the stub openings of the exploratory passage No. 1 of the l1 stratum, exploratory walker No. 2 of the stratum l1 and the installation walk of the exploration lava formation l1. As a result of the work, the technical documentation on the ventilation of the excavation section of the indigenous lava of formation l1 and the dead-end workings of the mine "Central Mine" State Enterprise "Mirnogadugol" was analyzed. Developed "Recommendations for ensuring dust and gas safety of works on excavation of coal in the indigenous lava of the l1 stratum, when releasing into the fresh stream of air entering its airing, outgoing air vents from the stub openings of the exploration passage No. 1 of the l1 stratum, exploration walk No. 2 of the l1 stratum assembly walkway exploration lava reservoir l1 Separated subdivision "Central Mine" of the State Enterprise "Mirnogadugol". The release of outgoing ventilation air jets from dead-end workings of exploration walk No. 1 of reservoir l1, exploration walk No. 2 of reservoir l1 and assembly walker of exploration lava of reservoir l1, horizon 622 m to the ventilation stream of fresh air supplied to the ventilation of the excavation section of primary lava of the reservoir l1, horizon 622 m , subject to the implementation of the developed recommendations for 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.
