Abstract: Aiming at the support technology of coal roadway with extra thick composite roof, taking the working face of A Coal
Mine as the background, this paper analyzed the displacement, stress and plastic zone distribution of the coal roadway with composite
roof in the original support scheme and optimized support scheme by using the finite element software FLAC3D, and
verified the rationality of the optimized support scheme for the extra thick composite roof.

Key words: composite roof; support technology; numerical simulation
