Information × Registration Number 0224U031542, 0123U102877 , R & D reports Title Conduct research on sources of methane release and approve the "Projects of the isolated diversion of the МВС" 8 of the northern bench of slope № 1 of layer l8 of the 550 m horizon and 2 of the southern bench of slope № 1 of layer l8 of the horizon of 550 m, to approve materials for assessing the technically achievable level (TАL) of residual air dust in underground workings, to calculate the parameters of "starved zones" (Development of recommendations for the arrangement of "starved zones") of 9 workings, to agree on the type 1-M ventilation scheme for the 8 excavation sites of the northern bench of the slope № 1 stratum l8 horizon 550 m and 2 southern benches of slope № 1 stratum l8 horizon 550 m, and to develop recommendations for the release of the output stream of air from the preparatory production into the stream of air of the extraction site, which enters under the conditions of the Сompany with additional responsibility "Mine "Bilozerska", in 2023. popup.stage_title Head Minieiev Serhii Р., д.т.н. Registration Date 12-05-2024 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of the study is dust, gas and fire safety in the conditions of the Company with Additional Responsibility "Mine "Bilozerska". The purpose of the work is to agree on the projects of the isolated removal of the methane-air mixture, to agree on the acts of establishing technically achievable levels of residual air dustiness of the cleaning and preparatory workings, to calculate the parameters of fire breaks for the Bilozerska Mine mine. Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, the technical documentation for working out 2 of the southern bench of slope №3 and 8 of the northern bench of slope №1 of the САR "Mine "Bilozerska" was analyzed. "Project of isolated removal of methane-air mixture from the produced space outside the excavated area 2 of the southern bench of slope № 3 through a pipeline with the help of gas-suction fans VMCG-7M" and "Project of isolated removal of methane-air mixture from the produced space outside the excavated area" section 8 of the northern bench of slope No. 1 through the pipeline with the help of gas suction fans VMCG-7M". Recommendations on ensuring gas safety during the operation of the VMCG-7M gas extraction unit of the excavation site 2 of the southern bench of slope № 3 and 8 of the northern bench of slope № 1. The calculation of the permissible level of dustiness based on the factor of critical dust loads has been carried out, and acts of establishing technically achievable levels of dustiness in the workings of САR "Mine "Bilozerska" have been agreed. As a result of the application of the developed recommendations, dust, gas and fire safety during mining operations is ensured, which is of great socio-economic and ecological importance.  Product Description popup.authors popup.nrat_date 2024-05-12 Close
