The purpose of the work is to develop the Project of degassing of the excavation section of the northern lava of formation l7 of block 4 of SE "Capital Mine" SE "Mirnogradvugillya" and recommendations for ensuring dust-safe working conditions. Research methods - generalization and analysis of results, methods mat. statistics, calculations according to standard methods. As a result of the work, the technical documentation for the development of the northern lava of formation l7 of block 4 of SE "Capital Mine" of SE "Mirnogradvugillya" was analyzed. The calculation of the expected methane release within the excavation site, the required degassing efficiency and the required air flow for ventilation of the treatment plant and the excavation site, parameters and mode of degassing of the roof wells, the required diameters of the pipeline. "Measures to control the degassing system of the excavation section of the northern lava of formation l7 of block 4 during fires in the mine workings" were developed. The project of degassing of the excavation section of the northern lava of formation l7 of block 4 of SE "Capital Mine" of SE "Mirnogradvugillya" has been developed. "Recommendations for ensuring dust-safe working conditions during the development of the northern lava of formation l7 of block 4 of SE" Capital Mine "of SE "Mirnogradvugillya" with air velocity in the treatment plant up to 6.0 m/s were developed. 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 2022-03-09 Close
