Abstract: In order to accurately determine the rock rock burst tendency, so the experiment of the acoustic emission (AE) for sandstone were made. Under the uniaxial loading rock burst, studied the deformation and acoustic emission characteristics. Analyzed of the load -deformation curve and AE characteristics, and got sandstone rock burst precursor information. The results show that, compaction phase and linear elastic stage AE ring-down count less. Cumulative energy curve is very flat, low elastic strain energy release. From the plastic deformation stage, AE activity was frequent, cumulative energy exponentially released, rock damage accelerated. Acoustic emission type from the previous burst-type becomes continuous. Stress -strain curve inflection point, are often AE Parameter Peak. The results showed that: monitored and analyzed the AE ring-down count, cumulative energy and rock damage, Can more accurately determine the sandstone rock burst tendency.
