Title

To carry out research of sources of methane release, to develop recommendations on release of an outgoing jet of air with a preparatory hole 883 of a collecting stream which enters into a fresh jet of air, preparatory production 883 of a cutting furnace, and recommendations on release of an outgoing jet of air with a preparatory hole 883 of a split furnace, carried out 883 prefabricated stream entering the fresh air stream of the preparatory face 883 of the cutting furnace of the reservoir с8н, conducted from the 881 prefabricated shunt, to develop a project of degassing the recessing section 883 of the «West-Donbass» mine, and to agree on the «Project of isolated removal of the МВС from the produced space of the recessing section 883 on short rigid pipelines at the expense of general mine depression» in the mine «West-Donbass» of the Production Structural Division «MINE MANAGEMENT TERNIVSKY» PJSC «DFEK Pavlogradvugillya».

 The object of the study is degassing of the coal-rock massif and ventilation of dead-end workings in the conditions of PJSC «DFEK Pavlogradvugillya». The purpose of the work is to develop technical solutions for the protection of gas and gas safety and the “Project of degassing of the excavation section 1039 of the С10в lava section of the mine «West-Donbass» of the PSD «MINE MANAGEMENT TERNIVSKY» PJSC «DFEK Pavlogradvugillya». Research methods – generalization and analysis of results, methods of mat. statistics, calculations by standard methods. As a result of the work, the technical documentation for the development of 883 lava and the dead-end workings of the mine «West-Donbass» of the PSD «MINE MANAGEMENT TERNIVSKY» PJSC «DFEK Pavlogradvugillya» was analyzed. The calculation of the expected methane release within the excavation site, the calculation of the air flow rate for ventilation of the treatment plant and the excavation site, the forecast of sudden methane breakthroughs from the mining soil, the calculation of the required diameters of the gas pipeline and the mode of operation of the vacuum pump. The parameters of drilling and technology of construction of degassing wells are determined. Measures have been developed to control the system of degassing during fires in mining. The project of degassing of the excavation section 883 of the С8н lava reservoir of mine «West-Donbass» of the PSD «MINE MANAGEMENT TERNIVSKY» PJSC «DFEK Pavlogradvugillya» was developed. Developed "Recommendations for ensuring the dust and gas safety of works during the deadlock production 883 of the split furnace at the outlet of fresh air entering the air, the outgoing ventilation air stream from the deadlock production 883 collective drift". Results of the implementation of the development – application of the developed recommendations made it possible to ensure gas safety during mining operations, which is of great socio-economic and environmental importance.
