The basis for carrying out the research is farm contract No. 953 dated February 7, 2018. "To carry out research on the possibility of using ejectors of the W model for ventilation of mine workings." Documents and materials submitted for consideration: – passport for W model ejectors; - Instruction manual for W model ejectors. It has been established that the ejectors of the W model can be used for the method of pumping ventilation of dead-end productions. At the same time, in mines dangerous due to gas and dust, the lag of the pipeline from the pit should not exceed 8 m, and in non-gas mines - 12 m. The parameters of the ejectors should be calculated taking into account the methane abundance of the workings, their length and cross-sectional area, as well as the intensity of mining operations. The work was completed in full according to the calendar plan. Product Description popup.authors popup.nrat_date 2023-02-07 Close
