The basic methods of estimation of liability to outburst of mountain massive resulting on strength properties of coal have been considered. Methods are based on the use of existing device P-1 constructed in A.A. Skochinsky IGD and device for determination of deformation and strength properties of outburst-prone massive, developed in IGTM NASU. The principle schemes of these devices and methods of determination of deformation and strength properties of coal and enclosing rock have been described. Device of IGTM NASU construction and the method of its use are protected by the patent. In general it has been formulated the methodology of application of mine express-methods to prognosticate the gas-dynamic state of coal massive during mining.
