Registration Date 01-01-2024 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of the research is the dust and gas safety of mining operations under the conditions of the РE "Capital Mine" of the SE "Myrnogradvugillia". The purpose of the work is to develop and approve technical documentation on ensuring dust and gas safety during the development of the 6th northern bench of the central slope of the layer l1 in the conditions of SE "Myrnogradvugillia". Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, the mining-geological and mining-technical characteristics of excavation site 6 of the northern bench of the central slope of the layer l1 were analyzed. "Recommendations for ensuring safe working conditions according to the dust factor during the development of the 6th northern bench of the central slope of the formation l1 with the speed of air movement in the cleaning production up to 6.0 m/s" have been developed. An assessment of the possibility and expediency of applying pre-moistening of the coal massif in working out 6 of the northern bench of the central slope of the layer l1 was carried out. "Measures to ensure the safe operation of the 6 northern bench of the central slope of the layer l1, as highly loaded with coal production of more than 1,000 tons per day and located at a depth of more than 1,000 m" were agreed. The calculation of the permissible level of dustiness based on the factor of critical dust loads for the РE "Capital Mine" of the SE "Myrnogradvugillia" was carried out, the Act of establishing technically achievable levels of residual air dustiness in the 6th northern bench of the central slope of the formation l1 was approved. 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 2024-01-01 Close
