Information × Registration Number 0219U101186, 0118U007643 , R & D reports Title To conduct a study of the sources of methane emissions, to agree «Project of ventilation and isolated drainage of methane from the produced lava space No. 134/1 of the horizon 557 m on a rigid metal pipeline with the help of a gas extraction facility ВМЦГ-7М» and to develop the "Draft of lava degassing № 134/1 of the reservoir n7n "Sokalsky" Separated subdivision" "Mine Stepova",State Enterprise "L'vovugol", according to the provided materials, in 2018 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 study is the degassing of the coal-bearing massif under the conditions of the Separated subdivision" "Mine Stepova",State Enterprise "L'vovugol". The purpose of the work is to investigate the sources of methane emission, to coordinate the “Project of ventilation and isolated removal of methane from the worked-out area of lava No. 134/1 through a rigid metal pipeline using a gas suction unit ВМЦГ-7М” and to develop the “Project of degassing No. 134/1 of Separated subdivision" "Mine Stepova",State Enterprise "L'vovugol". 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 mining of lava No. 134/1 of the n7n stratum of the Stepnaya mine of the Lvovugol state enterprise was analyzed. The calculation of the expected methane emission within the excavation site and the calculation of the air flow for ventilation of the excavation site. The justification of the choice of the method and scheme of degassing excavation site. The “Project for degassing lava No. 134/1 of the n7n stratum of the Separated subdivision" "Mine Stepova",State Enterprise "L'vovugol" was developed. The project for ventilation and isolated removal of methane from the depleted space of lava No. 134/1, horizon 557 m through a rigid metal pipeline with the help of a gas suction unit ВМЦГ-7М of the Separated subdivision" "Mine Stepova",State Enterprise "L'vovugol" was agreed upon. “Recommendations on ensuring gas safety during the operation of the ВМЦГ-7М gas-suction unit at the excavation section of the 134/1 lava of the n7n stratum of the Separated subdivision" "Mine Stepova",State Enterprise "L'vovugol" were developed. 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
