Remizov A. Parameters reasoning of mine working supporting method by discharging cavity during long wall mining method

Dissertation is devoted the parameters reasoning of the new mine working method with using discharging cavity during longwall mining method of inclined beds in Almaznaya - Maryevskiy geoindustrial district. Mine research conducting allowed to define a set of key factors influencing the state of mine working. The effective stressedly-deformed state calculating algorithm was developed on the basis of final element method for geomechanics tasks solving with the use of modern computers. Stressedly-deformed state analyzing and full-scale study allowed to define rational parameters of discharging cavity and mine working timbering. New dependentces of maximal vertical and horizontal shifting of inclined count our mine work for Almaznaya-Maryevskiy geoindustrial district specific mining conditions. Shifting rocks developing process into mine working experimental resarching as wel as technical and economical analyzing fulfilment on the area allows to talk that mine working supporting with discharging cavity using under longwall mining method is more effective than mining method using. It provides mine working stability during its term of exploitation. The research results have been used in the working documens of mine working optimization and have been introduced at UE "Pervomaysk Mine", SE "Pervomayskcoal".
