Krishnev A. Grounding of management parameters of coal seam the state of by vibration impact on it through surrounding rocks

The research is devoted to the grounding of management parameters of the coal seam state by vibration impact on it through surrounding rocks. The author reveals the realization of theoretical, laboratory and experimental researches where physical essence and vibration mechanism are determined by impact on tense gas-laden media. Also objective laws of management were established by the tensely-deformed state of critical area of coal seam formation by vibration impact on it through surrounding rocks and weakened zone of coal seam in the area of supporting pressure after vibration impact. The author defined important scientific positions, scientific novelty, scientific and practical meaningfulness and realization of the research performances, essence of vibration impact method. The active forces of vibration impact is considered to be a coal seam as a compact vibromachine (the hydraulic-powered support - surrounding rocks). The basic parameters of vibration impact were determined such as terms of application, parameters of process, technological parameters and criteria of efficiency. Basing on reasonable parameters are developed technological scheme of coal production out from steep layers by shield aggregates and from declivous layers by the hydroficated complexes with the use of vibration impact.
