Information × Registration Number 0221U105167, 0120U105209 , R & D reports Title Carry out research of methane sources and develop the Project of degassing of the excavation section 1 of the northern lava of the central panel of the block 11 of formation d4 of PJSC «Management of the mine «POKROVSKE», according to the provided materials, in 2020. popup.stage_title Head Minieiev Serhii Р., Registration Date 09-06-2021 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of research – degassing of the coal massif in the conditions of PJSC «Mine Management «Pokrovske». The purpose of the work is to develop a project of complex degassing of the excavation section 1 of the northern lava of the central panel of the block 11 of layer d4 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 working off the 1st northern bench of the central panel of the block 11 of PJSC «Mine Management «Pokrovske» was 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 1 of the northern lava of the central panel of the block 11 of the d4 formation during fires in the mine workings" have been developed. The project of complex degassing of the excavation section 1 of the northern lava of the central panel of the block 11 of layer d4 of PJSC «Mine Management «Pokrovske» has been developed. The results of the implementation of developments – 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 2021-06-09 Close
