Registration Date 03-08-2022 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 gas safety during mining operations in the conditions of the State Enterprise «Lvivvugillia». The purpose of the work is to develop recommendations for ensuring the dust and gas safety of coal mining operations in pit № 143 and the operation of the ВМЦГ -7M camera located in pit № 11, when releasing into the ventilation stream of air entering for their ventilation, the output ventilation stream of air from the dead-end mine stretch of formation n7n "Sokalskyi". Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, the ventilation schemes of the mine workings of the "Stepova" mine were analyzed. "Recommendations for ensuring dust and gas safety of coal mining operations in pit № 143 of the n7n "Sokalskyi" layer and operation of the ВМЦГ-7M camera, located in pit № 11, when releasing into the ventilation jet of air entering for their ventilation, the exit ventilation jet of air from the dead-end mining of layer n7n "Sokalskyi" of the "Stepova" mine of the SE "Lvivvugillia". It was agreed to release the output ventilation jet of air from dead-end production 145 of the exploration stretch into the ventilation jet of air entering for ventilation of the excavated area of lava № 143 of layer n7n "Sokalskyi" and the camera ВМЦГ-7M, located in failure № 1, subject to the implementation of the developed recommendations. The results of the implementation of developments - the application of the developed recommendations made it possible to ensure gas safety during mining operations, which is of great socio-economic and ecological importance.  Product Description popup.authors popup.nrat_date 2022-08-03 Close
