Information × Registration Number 0212U006619, 0110U003882 , R & D reports Title Grand of scientific and technical help during conducting of experimental works on degassing and lowering of gas dynamic activity of the coal layer k8- "Camenca" and L7top- "Pugachovca". popup.stage_title Head Sofiyskij Konstantin Konstantinovich, Доктор технічних наук Registration Date 30-05-2012 Organization Institute of Geotechnical mechanics of NAS of Ukraine popup.description2 Object of studies - process of effective degasification of bubble-point minig masiff with application on it of hydrodynamic affecting through technological wells. Subject of research - arguments of method of hydrodynamic affecting on effective degasification of a bench coal. Methods of studies - on the basis of analytical and mine experimental researches of process of hydrodynamic affecting on a bench coal l7top- "Pugachevka" of a lease №95 and process of a gas emission of the treated band after its conducting in bottom of longwall №95, has been instituted a time history of average daily concentration of methane in a gas-air mixture on return air from longwall, and also a size of bands of treating of a massif. By results of definition of the floor space of a band of treating and magnitude of variation of average daily concentration of methane taking into account its background value and daily quantity of air on longwall return air the coefficient of degasification of a bench coal through technological well № 1-0,55, radius of treating of a massif of 25 m and coefficient of an intensification of a seam degassing 1,19 is instituted. Efficiency of hydrodynamic affecting as a method of an intensification of degasification and decrease of gasdynamic activity in affected area of technological wells is erected. Coal-face works in bottom of longwall №95 are spent without indications of gasdynamic appearances. HYDRODYNAMIC AFFECTING, TECHNOLOGICAL WELLS, AVERAGE DAILY CONCENTRATION, STRAIN MASSIF, DEGASIFICATION COEFFICIENT, COEFFICIENT DEGASIFICATION INTENSIFICATION.
