Abstract
The present invention discloses an acoustic emission monitoring and transmission system for engineering rock mass including an acoustic emission sensor and a ground workstation. The acoustic emission sensor is installed in a borehole of the monitored rock mass and transmits a received monitoring signal to the ground workstation through a cable. The acoustic emission sensor includes an acoustic emission probe, a probe installation mechanism and a transmission mechanism which transmits the probe installation mechanism with the acoustic emission probe to a setting position inside the borehole. The probe installation mechanism includes a shell connecting to the transmission mechanism and a probe sleeve for accommodating the acoustic emission probe.
