Information × Registration Number 0224U031608, 0123U103179 , R & D reports Title Provide scientific and technical assistance in the development of technical solutions and agree technical documentation on ensuring gas safety of works for the project "Safe development of coal seams, according to the gas factor in mining and geological conditions of mines, dangerous due to gas dynamic phenomena", in 2023. popup.stage_title Head Minieiev Serhii Р., д.т.н. Registration Date 23-05-2024 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 to ensure gas safety in the conditions of "Krasnolymanske" LLC. The purpose of the work is to develop technical solutions and agree on design and technical documentation to ensure gas safety in the mining and geological conditions of "Krasnolymanske" LLC. 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 the 2 northern lava of the k5 reservoir of "Krasnolymanske" LLC were analyzed. The calculation of the expected release of methane within the mining area, the air consumption for ventilation of the mining area, the parameters and mode of degassing of the produced space was carried out, and the "Recommendations for the comprehensive degassing of the mining area 2 of the northern bench of the formation k5v to the project of dissection and preparation of reserves of mine area No. 2" were developed. "Recommendations for ensuring the safe working out of the k5v coal seam, which is dangerous due to sudden emissions of coal and gas, highly loaded excavation areas when fresh air is supplied to the cleaning pit one piece at a time without refreshing the output ventilation air stream". The analysis of the "Project of AGK SE "Coal Company "Krasnolymanska" for 2023" was performed and comments on it were developed. The adjusted draft of the AGK was agreed. As a result of the application of the developed recommendations, safety during mining operations is ensured, which is of great socio-economic and ecological importance.  Product Description popup.authors popup.nrat_date 2024-05-23 Close
