Rock damage acoustic monitoring system
The invention discloses a rock damage acoustic monitoring system including an acoustic emission sensor installed in a borehole of a monitored rock mass and a ground workstation. The acoustic emission sensor is composed of an acoustic emission probe and a probe installation mechanism for installing the acoustic emission probe and a transmission mechanism for transmitting the probe installation mechanism. The probe installation mechanism includes a shell, a probe sleeve installed in the shell, an end cap fixed on the upper end surface of the probe sleeve, and a piston hydro-cylinder arranged between the top of the inner wall of the shell and the end cap. The present invention realizes the control of the moving direction of the shell and the probe sleeve by the piston hydro-cylinder component and the hydraulic pump.
