Abstract.

The criterion of ecological risks estimation of high-performanced coal mines functioning with the use of the complex degassing and subsequent utilization of methane was grounded. A criterion is differently takes into account the volumes of methane emission in an atmosphere and drainaged methane, and also additive takes into account the organized and unorganized  troop landings (permanent and dynamic constituents of criterion) of hotbed gases from coal mines. The use of this criterion allowed to give ecological estimation of developed technical decisions for decline of the troop landings of methane in an atmosphere.

Conducted researches and set conformities to the law: redistributions of methane in an coal-rock array under action of cleansing works; between productivity of cleansing face and its methane capacity, hyperbolical dependence of duration of degassing of coal-rock array on the size of making its blocks, that allowed to define the rational parameters (amounts and corners of direction of «bushes») of decontamination mining holes. The examples of re-configuration structure of the mine ventslation system by the change of charts of ventilation in the process of working off a mining post are resulted. It is expounded basic positions calculation of the decontamination systems taking into account the factors of inundation and muddiness of transported methane-air mixture.

Keywords: action of methane on an environment, methane yield in coal layers, troop landings of methane in an atmosphere, decontamination mining holes, methane-capasity of coal mines, imitation modelling, criterion of ecological risk estimation.
