Factors that influence the use of technical potential of longwall shearers, associated with its proper selection to the given natural conditions of the face, techno- logical process in the face as well as to the availability of machines and equipment that make a technological line face – shaft tank, were analyzed. An impact ot the mechanical system availability on the production rate was given on an example of the face equipped with the KSW/E-620 shearer. The readiness factor of the shearer and other components of longwall system was presented. The factors which determine the use of a theoretical shearer’s output were given on an example of KSW-500 shearer operational tests. The efficiency factor of technology, which determines a degree of the face production potential usage was discussed.
