Registration Date 17-06-2024 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of the study is the degassing of coal massif under the conditions of "Krasnolymanska" LLC. The purpose of the work is to develop the "Project of complex degassing of mining areas of SE "СС "Krasnolymanska" within the mining concession of LLC "Krasnolymanska" on layers l3 and m42, taking into account the prospect of development of mining operations until 2027." Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, the mining-geological and mining technical conditions of working out 7 southern benches of slope No. 1 of layer m4, 1 bench of northern slope No. 1 of L3 layer and 3 northern benches of slope No. 1 of L3 layer were analyzed. The calculation of the expected release of methane and MPS within the extraction sites, the air consumption for their ventilation, the consumption of methane that must be captured from the roof with wells and from the produced space with "candles", the parameters of drilling and the technology of construction of degassing wells, the necessary diameters of degassing gas pipelines for capturing MPS was performed wells Measures have been developed to manage the degassing system during fires in mining operations. The "Project of complex degassing of mining areas of SE "СС "Krasnolymanska" within the mining concession of "Krasnolymanska" LLC on layers l3 and m42, taking into account the perspective of the development of mining operations until 2027, was developed. The "Conclusion on calculation of air consumption for ventilation of excavation area 6 of the northern bench of slope No. 1, made according to the results of a gas survey conducted by workers of the depression, gas and thermal survey service of 10 VGRZ" was developed. The results of the implementation of developments - the application of the developed recommendations made it possible to ensure gas safety, which is of great socio-economic and ecological importance Product Description popup.authors popup.nrat_date 2024-06-17 Close
