      ABSTRACT

      The problem of perfection of technology of action on coal stratums in order to control of their status for prevention of dangerous phenomenon during underground coal extraction is considered. The joint application of hydraulic and pneumatic action as a way of reduction of gas and dust extraction is proposed.
