Information × Registration Number 0224U031522, 0123U102391 , R & D reports Title To conduct a study of sources of methane release and develop a "Project of degassing using an underground degassing unit from the produced space of the excavation site in the conditions of the «Samarska» mine" PSU «MINE MANAGEMENT «DNIPROVSKЕ» PJSC "DFEK PAVLOGRADVUHILLYA", to develop recommendations for ensuring the gas safety of works when releasing the outgoing ventilation stream of air into the incoming ventilation stream and to agree on materials for assessing the technically acceptable level (TАL) of residual air dust in underground workings in 2023. popup.stage_title Head Minieiev Serhii Р., д.т.н. Registration Date 08-05-2024 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 the dust and gas safety of extraction sites in the conditions of PJSC «DFEС Pavlogradvugillya»". The purpose of the work is to develop the "Project of degassing of the excavation area 1004 of lava of layer C10v of the mine "Samarska" PSU "Mine Management Dniprovske" PJSC «DFEС Pavlogradvugillya»" and to coordinate the materials for assessing the technically permissible level of residual air dust in underground workings. 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 characteristics of the excavation site 1004 lava of layer C10v of the mine "Samarska" PSU "Mine Management Dniprovske" PJSC «DFEС Pavlogradvugillya» were analyzed. The calculation of the expected release of methane within the extraction area, the calculation of the expected gas balance of the extraction area of 1004 lavas at the planned load of 3100 t/day was performed. Measures have been developed to manage the degassing system of the mining area during fires in mining workings. The "Project of degassing of the excavation area 1004 of lava of layer C10v of the mine "Samarska" PSU "Mine Management Dniprovske" PJSC «DFEС Pavlogradvugillya»" was developed. The calculation of the permissible dust level based on the factor of critical dust loads was carried out and the technically achievable levels of residual dust for the mine workings of the «Samarska» mine were established. As a result of the application of the developed recommendations, the safety of mining operations is ensured, which is of great socio-economic and ecological importance.  Product Description popup.authors popup.nrat_date 2024-05-08 Close
