Bokij O. Decline of ecological risk of the troop landings of mine methane in an atmosphere in coal mines

Research object: process of emission of methane of coal mines with subsequent its utilization. The decline of ecological risk of the troop landings of methane in an atmosphere on coal mines by the ground of complex criterion of estimation of ecological risk of the troop landings of mine methane in an atmosphere and establishment of conformities to the law of methane-apportsonment for the choice of effective facilities of his catching at development of coal deposits is the purpose of dissertation. For achievement of the put aims the analysis and generalization of scientific and technical achievements in area of ecological safety of functioning of coal mines and methods is used in work: ecology-mathematical analysis - for the ground of complex criterion of estimation of risks of the troop landings of mine methane in an atmosphere; stream programming - for research of emission of methane in the mine working of mines, and also on an earthly surface; economic analysis - for the ground of technical decisions on perfection of technologies of drainage and utilization of methane in coal mines; approbation of the offered technological solutions in the conditions of the real production. The criterion of estimation of ecological risks of functioning of high-performance coal mines with the use of the complex degassing and further utilization of methane is grounded. A criterion differentiated takes into account the volumes of emission of meth-ane in an atmosphere and removal methane, and into account the organized and unorgan-ized troop landings of hotbed gases from coal mines. The use of this criterion allowed to give ecological estimation to the developed technical decisions of decline of the troop landings of methane in an atmosphere. Researches are conducted and conformities to the law are set redistributions of methane in an coal-rock array under action of cleansing works. Rational technological measures on reduction of emission of mine methane in an atmosphere, including, are grounded: choice of the modes of operations of ventilators of above all ventilation, providing creation of zero depression area for the management of methane-apportionment from the produced space; irrigation of the produced space by the specially prepared mixture; preliminary electric-kindle for the use of mixture with low maintenance of methane in the cogeneration stations. It is drawn on got result at perfection of the system of the complex degassing of O.F. Zasyad'ko mine and in the educational process of DonNTU.
