The subject of research - process of pneumohydrodynamic parameters influence on the massif through surface degassing borehole. The aim of this industrial testing method for developing parameters of pneumohydrodynamic impact on the mining massif through surface degassing borehole, which will increase the extraction of methane from surface boreholes. Methods of researches - analytical, theoretical, experimental in industrial conditions. As a result of industrial tests of "Method of degassing coal rock mass for the intensification of methane extraction through the surface degassing borehole with pneumohydrodynamic impact" on the PJSC "Mine named by A.F. Zasyadko " the mathematical model is obtained that describes the influence of factors pneumohydrodynamic impact on the gas-saturated coal massif with full factorial experiment and determination of the radius of influence of the impact parameters. The technological regulations intensification of coal bed methane extraction pneumohydrodynamic impact on the SDBH MT-340 and ZD-8 PJSC "Mine named by A.F. Zasyadko "and influence process parameters are adjusted.PNEUMOHYDRODYNAMIC IMPACT, METHOD, SURFACE DEGASSING BOREHOLES, COLMATATION, METHANE, THE RADIUS OF INFLUENCE, DEGASSING, FLOW RATE, PRODUCTION INTERVAL Product Description popup.authors Агаєв Руслан Агагулуєвич Барадулін Євгеній Григорович Власенко Василь Вікторович Гаврилов Вячеслав Іванович Петух Олександр Петрович Притула Дмитрій Олександрович Силін Дмитро Павлович Софійський Констянтин Константинович Шейко Анатолій Васильович popup.nrat_date 2020-04-02 Close
