Information × Registration Number 0212U006189, 0112U001571 , R & D reports Title Giving of the scientific and technical help at hydrodynamic affecting from industrial crosscut №14 on a seam coal m3 - "Tolstuj" in bottom of longwall №41 - 1146 m popup.stage_title Head Sofiyskij Konstantin Konstantinovich, Доктор технічних наук Registration Date 01-03-2012 Organization Institute of Geotechnical mechanics of NAS of Ukraine popup.description2 The object of researches - process of effective degasification of bubble-point hills with application on it of hydrodynamic affecting through technological wells. The subject of researches - parameters of method of hydrodynamic affecting on effective degasification of a seam coal. Methods of researches - on the basis of analytical and mine experimental researches of process of hydrodynamic affecting on a coal seam m3 - "Tolstuj" a lease №41 and process of a gas emission of the treated zone after its conducting in bottom of the desk №13 completed by the shield aggregate, has been instituted a time history of average daily concentration of methane in a gas-air mixture on return air from longwall, and also sizes of zones of treating of a massive. By results of definition of the floor space of zone of treating and value of variation of average daily concentration of methane taking into account her background value and diurnal quantity of air on longwall return air the coefficient of degasification of a coal seam of the desk №13 through technological well № 1-0,58, radius of treating of a massive of 29 m and coefficient of an intensification of degasification of the desk №13-1,34 is certain. Efficiency of magnetohydrodynamic 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 a band №13 and baring of a coal seam by an intermediate crosscut №14 are made without signs of the gasdynamic phenomena. HYDRODYNAMIC AFFECTING, TECHNOLOGICAL WELLS, AVERAGE DAILY CONCENTRATION, STRAIN MASSIVE, DEGASIFICATION COEFFICIENT, COEFFICIENT DEGASIFICATION INTENSIFICATION.
