The purpose of the work is to study the efficiency and expediency of the construction of degassing well bushes in front of the cleaning pit when using a direct-flow ventilation scheme of type 3-B in the conditions of PJSC «Management of the mine "POKROVSKE". Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard and developed methods, experimental studies. As a result of the work, the "Methodology for evaluating the efficiency of drilling parameters of degassing wells and the quality of sealing their mouths" was developed. The design of the device for measuring methane concentration along the length of the degassing well was developed. The calculation of the parameters of drilling experimental degassing wells in front and behind the cleaning hole 8 of the northern bench of block 10 of PJSC «Management of the mine "POKROVSKE" was performed. An experimental evaluation of the efficiency of drilling parameters of degassing wells and the quality of their mouth sealing was performed. 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 2022-09-04 Close
