The purpose of the work is to develop technical solutions for the safe exploitation of coal seams by the gas factor in the mining and geological conditions of the mine "Dniprovska" PSD "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 technical documentation for working out 1154 beds of layer C10v of the mine "Dniprovska" PSD "Mine management Dniprovske" PJSC «DFEС Pavlogradvugillya» was analyzed. The calculation of the expected release of methane within the excavation area, the air consumption for ventilation of the cleaning production and the excavation area, the parameters and mode of degassing of the roof by wells, and the required diameters of the gas pipeline were performed. "The project of degassing of the excavation area 1154 of the stratum C10v of the mine "Dniprovska" PSD "Mine management Dniprovske" PJSC «DFEС Pavlogradvugillya» was developed. Recommendations on ensuring dust and gas safety of works during dead-end workings of the Dniprovska mine have been developed. The project of the Dniprovska Mine AGK for 2021 was agreed. The acts of establishing technically achievable levels of air dust in the underground workings of the Dniprovska mine were agreed. The results of the implementation of developments - the application of the developed recommendations made it possible to ensure gas safety during mining operations, which is of great socio-economic and ecological importance.  Product Description popup.authors popup.nrat_date 2022-12-13 Close
