Experimental study on failure precursors of coal and sandstone based on two‐step clustering of acoustic emission characteristics
Abstract Accurately determining the precursors of coal and rock failures is crucial for preventing associated risks in coal mines. In this study, based on the values of the four parameters amplitude, duration, counts and energy of acoustic emission (AE) signals, the AE signals of coal and sandstone...
