Information × Registration Number 0221U103723, 0119U103066 , R & D reports Title Conduct research on methane release sources and develop a project for degassing the produced space of the 151 lava mining site, agree on the project for removing methane from the produced space of the 175 lava reservoir C6, and develop recommendations for the release of the output stream of preparatory potholes in the conditions of the «Stepova» Production Structural Division «PERSHOTRAVENSKE» of the Private Joint Stock Company «DFEK PAVLOGRADUGOL». popup.stage_title Head Minieiev Serhii P., Доктор технічних наук Registration Date 24-02-2021 Organization Institute of Geotechnical mechanics of NAS of Ukraine popup.description2 The object of research is degassing of the coal massif in the conditions of PJSC «DFEK Pavlohradvugillya». The purpose of the work is to develop a "Project for degassing the produced space of the excavation section 151 lava" and recommendations for the release of the output air jet from the preparatory pits in the conditions of the mine "Stepova". Research methods - generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the technical documentation for the development of 151 lavas of formation C6 and the dead-end workings of the mine "Stepova" PSD «Pershotravenske» of the PJSC «DFEK Pavlohradvugillya» was analyzed. The calculation of the expected methane release within the excavation site, the calculation of air flow for ventilation of the treatment plant and the excavation site, the forecast of sudden methane breakthroughs from the soil of mine workings, the calculation of the required pipeline diameters and vacuum pump mode. Measures have been developed to control the degassing system during fires in mine workings. The project of degassing of the excavation section of 151 lava of the C6 formation of the Stepova mine of the PSD «Pershotravenske» of the PJSC «DFEK Pavlohradvugillya» has been developed. "Recommendations for ensuring dust and gas safety of works during the dead-end development of 178 prefabricated road from the horizon of 300 m when releasing into the fresh stream of air coming to its ventilation, the output ventilation air stream from the dead-end development of the western main rolling road". The results of the implementation of developments - the application of the developed recommendations allowed to ensure gas safety during mining operations, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2021-02-24 Close
