    In this paper it has been presented the analytical solutions considering influence of elastic yield of individual props on loading capacity of roof support used in underground drifts. The analytical relations were obtained as a result of solutions of sets of canonical equations forces method. In the presented problem the sets of canonical equations arise from direct application of five moments equations (or theorem). Solutions actually published in the literature, resulted from equation (or theorem) of three moments, do not allow for including within the calculations the elastic yield property of the props. These solutions are particular cases of those presented in the paper. The successful analytical solutions of the equations were possible thanks to application of CAS type software. This kind of codes allow to solve problems, that were impossible for solution in the past.
