The purpose of the work is to develop a project for temporary degassing of excavation sites of unit 11 of PSD "Mine management Pershotravenske” PJSC "DFEK PAVLOHRADVUGILLYA" and recommendations for sequential ventilation of the preparatory pits of the mine "Jubileinа". Research methods – generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the mining-geological and mining-technical characteristics of the excavation sections and dead-end workings of the mine "Jubileinа" of the PSD "Mine management Pershotravenske” PJSC "DFEK PAVLOHRADVUGILLYA" were analyzed. The calculation of the actual gas balance of the excavation site, parameters and degassing modes of the produced space is performed. "Measures to control the degassing system of the excavation site during fires in the mine workings" have been developed. The project of degassing of the produced space 130 of the lava of the C6 formation and the spent excavation sections of the №3 block of the mine "Jubileinа" has been developed. Recommendations have been developed to ensure dust and gas safety of work on dead-end workings during the installation of local ventilation fans in workings with an initial ventilation air flow. As a result of the application of the developed recommendations, gas safety during mining operations is ensured, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2021-05-09 Close
