The invention discloses a rock mass damage monitoring system in a deep engineering environment. The rock mass damage monitoring system in the deep engineering environment comprises an acoustic emission sensor assembly and an acoustic emission amplifier assembly mounted on a rock mechanics test machine; an acoustic emission sensor fixture comprises a coupling screw and a fixture cover, a fixture cylinder and a coupling panel connected through thread sequentially; and the acoustic emission amplifier assembly comprises an acoustic emission amplifier, a rail-mounted column, a lifting support plateand a support plate lifting cylinder. The rock mass damage monitoring system in the deep engineering environment disclosed by the invention solves the problem of acoustic emission signal interferenceand signal inaccuracy under the conditions of three-axis high temperature and high confining pressure during the process of rock damage and breakage test under high temperature and high pressure. Theinvention also provides an
