Information × Registration Number 0220U102864, 0119U103882 , R & D reports Title To carry out research into methane sources and to develop a project for degassing the excavation section of the indigenous lava section of the horizon 593 m layer d4 of PJSC «Management of the mine «POKROVSKE», according to the submitted materials, in 2019. popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 15-06-2020 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 «Mine Management «Pokrovske». The purpose of the work is to develop the Project of degassing of the excavation section of the root lava of the horizon of 593 m of the d4 formation of PJSC «Mine Management «Pokrovske». Research methods – generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the technical documentation for testing the root lava of the mountains was analyzed horizon of 593 m of formation d4 of PJSC «Mine Management «Pokrovske». 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. Developed "Measures to manage the degassing system of the excavation site of the root lava of the mountains horizon of 593 m of d4 formation during fires in mine workings». Developed "Project for degassing of the excavation site of the root lava of the mountains horizon of 593 m of formation d4 of PJSC «Mine Management «Pokrovske». The results of the implementation of developments – the application of the developed recommendations allowed to ensure gas safety during mining operations, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2020-07-03 Close
