In order to raise the performance of tunnel drilling rig with all hydraulic head type, pump-controlled technology was applied in hydraulic system design. Working condition and basic circuit of hydraulic system were analyzed in this paper, at the base of which some disadvantages of the hydraulic system with valve-controlled technology were introduced.
