The purpose of the work is to develop the "Project for the degassing of the excavated area of lava № 136 of the n7n layer" and agree on the "Project for ventilation and isolated removal of methane from the produced space of lava № 136 through a rigid metal pipeline with the help of a gas suction unit VMCG-7M". 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 conditions of working out were analyzed. The analysis of mining-geological and mining-technical conditions of working-out of the mining section of lava № 136 of layer n7n of the SE "Stepova Mine" of the SE "Lvivvugillya" was performed. The calculation of the expected release of methane within the excavation area, the air consumption for ventilating the excavation area, the performance of the degassing system was performed, and the choice of the method and scheme of degassing of the excavation area was substantiated. Measures have been developed to manage the degassing system during fires in mining operations. The "Project of degassing of the mining area of lava № 136 of layer n7n of the Stepova mine of the SE "Stepova" Mine" of the SE "Lvivvugillya" was developed. "Recommendations for ensuring gas safety during the operation of the VMCG-7M gas extraction unit of the mining area of lava № 136 of layer n7n of the SE "Stepova" Mine" of the SE "Lvivvugillya" have been developed. The "Project of venting and isolated removal of methane from the produced space of lava № 136 through a rigid metal pipeline using a gas suction unit VMCG-7M of the SE "Stepova" Mine" of the SE "Lvivvugillya" was agreed. As a result of applying the developed recommendations, gas safety will be increased. Product Description popup.authors popup.nrat_date 2025-01-12 Close
