Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of the study is the ventilation of the excavation site of the Dobropolskaya mine. The purpose of the work is to conduct a study of methane emission sources and develop recommendations for ensuring the gas safety of a high-loaded excavation section 9 of the northern lava of the slope of the m51 reservoir in the Dobropolskaya mine and PSS "DniprovskoeMineGroup", Limit liability company "DTEK Dobropolyeugol" when using a backflow ventilation scheme of the type 1-M. Research methods - generalization and analysis of results, methods of mathematical statistics, calculations using standard methods. As a result of the work, the technical documentation for airing the excavation section 9 of the northern lava of the slope of the formation m51 in the Dobropolskaya mine of the industrial-production zone PSS "DniprovskoeMineGroup", Limit liability company "DTEK Dobropolyeugol" was analyzed. “Recommendations were developed for ensuring gas safety of a high-loaded (more than 1000 tons / day) excavation site 9 of the northern lava of the slope of the seam m51 in the Dobropolskaya mine PSS "DniprovskoeMineGroup", Limit liability company "DTEK Dobropolyeugol" using a returnable ventilation pattern, type 1-М.". The use of a return-type type 1-M ventilation pattern of a highly loaded (more than 1000 t / day) excavation section 9 of the northern lava of the slope of the formation m51 horizon 450 m and the calculation of the air flow necessary for ventilation has been agreed, 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.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
