Information × Registration Number 0221U105101, 0120U105204 , R & D reports Title To conduct research on methane sources and develop a project for degassing of the excavation section 3 of the southern lava of block 7 of layer d4 of PJSC «Mine management «POKROVSKE», according to the provided materials, in 2020. popup.stage_title Head Minieiev Serhii Р., Registration Date 04-06-2021 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of research is degassing of the coal massif in the conditions of PJSC «Management of the mine «POKROVSKE». The purpose of the work is to develop a project of complex degassing of the excavation section 3 of the southern lava of block 7 of layer d4 of PJSC «Management of the mine «POKROVSKE». Research methods – generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of performance of work the technical documentation on working off of 3 southern lava of block 7 of PJSC «Management of the mine «POKROVSKE» is analyzed. The calculation of the expected methane release within the excavation site, the required degassing efficiency and the maximum allowable load on the treatment face by the gas factor, parameters and mode of degassing of the roof by wells, the required diameters of the pipeline. "Measures to control the degassing system of the excavation section 3 of the southern lava of the block 7 of formation d4 during fires in the mine workings" have been developed. The project of complex degassing of the excavation section 3 of the southern lava of the block 7 of the d4 formation of PJSC «Management of the mine «POKROVSKE» has been developed. The results of the implementation of developments – the application of the developed recommendations allowed to ensure gas safety during mining, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2021-06-04 Close
