Ultrasonic characteristics and equivalent crack width of coal and rock bodies around boreholes during progressive failure
The ultrasonic characteristics of the coal and rock bodies around boreholes during failure are closely related to the crack propagation law. To investigate the ultrasonic characteristics and crack propagation law of coal and rock bodies around boreholes, different grouting samples with boreholes wer...
