Abstract. The method determination of project power by the mining factor of mines elaborative steep coal layers on deep horizons is improved in this work. A difference from the known methods is that loadings on lavas are determined taking into account a new conformity to the law of influencing of depth mining of coal layers and tectonic features of deposits on the outburst hazard of coal layers. The coefficient of simultaneity work of lavas is determined by a calculation way depending on the amount of working layers in the mine field and number of the simultaneously unsealed and worked floors. The conformities to the law of change of loadings on lavas and coefficient of simultaneous their work, set on the basis of generalization of experience mines for protracted period, are represented. Taking into account the represented method powers of mines on large depths and maximum depth of development of coal layers for the mines of the Central district of Donbassa, which on technscal-economical terms correspond to the depths of to 1500 м, are grounded. Progressive technological charts of dissection and preparation of layers are developed and ratified by Minugleprom of Ukraine.
Keywords: production capacity of mine, depth of development, loading on breakade face, gasdynamical activity of layer.
