Registration Date 22-03-2023 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 safety of mining operations in the workings of the «Dniprovska» mine. 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" PSU «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, mining-geological and mining-technical characteristics of mining areas and dead-end workings of the mine "Dniprovska" of PSU «Mine management Dniprovske" PJSC «DFEС Pavlogradvugillya» were 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, drilling parameters and the technology of construction of degassing wells was performed. The "Project of degassing of the excavation area 1186 lava of layer C10v of the «Dniprovska» mine was developed. "Recommendations for ensuring dust and gas safety of works during ventilation and maintenance of the dead-end working of the 1186 assembly line when releasing into the ventilation jet of air entering for its ventilation, the outgoing air jet from the dead-end working of the western main roll-back line" was developed. Work has been carried out to establish technically achievable levels of final air dustiness in the workings of the «Dniprovska» mine of the PSU «Mine management Dniprovske" PJSC «DFEС Pavlogradvugillya». 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 2023-03-22 Close
