The invention discloses a recovery type on-site sound emission sensor, which comprises a sound emission probe, a probe installation mechanism, and a delivery mechanism for delivering a combination body of the sound emission probe and the probe installation mechanism to a setting position in a drill hole of a rock mass to be monitored. The probe installation mechanism comprises a shell, a probe sleeve, spring sleeves, springs and a fixed pulley assembly; the probe sleeve is installed in a shell guiding cylinder; the spring sleeves are fixed to two sides of the probe sleeve; the springs are installed in the spring sleeves; one end of a first rope in the fixed pulley assembly is fixedly connected with an end cover on the upper end face of the probe sleeve through a fixed pulley arranged on the top part of the inner wall of the shell. According to the recovery type on-site sound emission sensor provided by the invention, through interaction of the first rope and the springs arranged between the shell and the prob
