Abstract: During the period of construction and operation，the geotechnical engineering often undergoes the effect of the under-ground water and compression of the construction and operation.And the mechanical property under such condition is one of the major factors affecting the long term stability.The summary was conducted based on both national and international researches，including the mechanical properties of moisture-containing coal and rock under uniaxial compression，cyclic loading，triaxial loading，shearing test and tension test，and its AE properties.The current researches at home and abroad were reviewed and analyzed，and then the laws of mechanical properties and AE characteristics of moisture-containing coal and rock were summarized.It is found that with the wide use of the AE technology in the monitoring of geotechnical engineering stability and the development of various test methods，the AE of containing moisture coal and rock trends to the true triaxial and multi-field coupling.Also，with the fast development of the numerical analysis software and parallel technology， the numerical simulation can be a new way to study the AE properties of containing moisture coal and rock.

Key words: Moisture-containing coal and rock, Different stress paths, Damage, Acoustic emission(AE)
