Registration Date 30-01-2024 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of the research is the degassing of coal massif under the conditions of PJSC «DFEС Pavlogradvugillya». The purpose of the work is to develop the "Corrective project of degassing of the mining area 1002 of the stratum C10v of the mine "Samarska" PJV "Mine management «Dniprovske» PJSC «DFEС Pavlogradvugillya». 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 mining area of the preparatory dead-end workings of 1004 assembly line and conveyor line of layer C10v of the "Samarska" mine of the PJV "Mine management "Dniprovske" PJSC «DFEС Pavlogradvugillya» were analyzed. Calculation of drilling parameters and technology of construction of degassing wells in preparatory productions, as well as diameters of gas pipelines and operation mode of vacuum pumps was performed. An addition to the section on degassing regimes of the excavated area of 1002 lava during firefighting has been developed, taking into account changes in degassing parameters. The "Supplement to the Project of degassing of the excavation area 1002 of the strata layer C10v of the «Samarska» mine of the PJV "Mine management «Dniprovske» and PJSC «DFEС Pavlogradvugillya» was developed. 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 2024-01-30 Close
