The invention discloses a pressure coupling rock fracturing acoustic monitoring system. The pressure coupling rock fracturing acoustic monitoring system comprises an acoustic transmitting sensor installed in a borehole of a monitored rock body and a ground workstation, wherein the acoustic transmitting sensor consists of an acoustic transmitting probe, a probe mounting mechanism for mounting the acoustic transmitting probe and a transferring mechanism for transferring the probe mounting mechanism, and the probe mounting mechanism comprises a shell, a probe sleeve installed in the shell, an end cover fixed at the upper end surface of the probe sleeve and a piston oil cylinder assembly arranged between the top of the inner wall of the shell and the end cover. The movement direction of the shell and the probe sleeve is controlled by virtue of the piston oil cylinder assembly and a hydraulic pump, so that the difficulty in effectively mounting and coupling the acoustic transmitting probe can be solved, the effect
