The purpose of the work is to develop the "Project of degassing of excavation sites of PJSC «Mine Management «Pokrovske» for 2021." Research methods - generalization and analysis of results, methods mat. statistics, calculations by standard methods. As a result of the work, the plan for the development of mining operations at PJSC «Mine Management «Pokrovske» in 2021 was analyzed. The analysis of mining-geological and mining-technical characteristics of the designed excavation sections 4 of the lava of the southern panel of block 10, 13 of the southern lava of block 10, 9 of the northern "bis" lava of block 10, 4 of the southern lava of block 7, 7 of the northern lava of block 10, 1 of the southern lava block 1, the whole bench of blocks 2-3. The calculation of the expected methane release within the excavation sections, the required degassing efficiency and air flow for ventilation of the designed excavation sections, parameters and mode of degassing of the roof by wells and the produced space, the required diameters of the pipeline. The project of degassing of excavation sites of PJSC «Mine Management «Pokrovske» for 2021" is developed. The results of the implementation of developments - the application of the developed recommendations allowed to ensure gas safety during mining, which is of great socio-economic and environmental importance.  Product Description popup.authors popup.nrat_date 2022-03-09 Close
