The monograph is devoted to the problems of substantiation of the parameters for contiguous &#13;\ncoal seam extraction using powered systems under complex mining and geological conditions. &#13;\nRational parameters (strength and geometrical parameters of a powered support, allowable distance &#13;\nbetween stopes within contiguous seams, shearer feed rate, longwall advance rate) for stoping operations in Lvov region mines are determined. Recommendations as for the parameters for contiguous sea
