| Abstract: | The definition of released circle of surrounding rock was explained in this paper,moreover,the principle and characteristics of acoustic detection were also introduced.Based on the on-site geological conditions,ultrasonic detection system was used to measure released circle of different roadway of shaft bottom in Jinding Coal Mine,the variation law of wave velocity versus depth of drilling hole were analysed.The results show that,the thickness of released circle in different points has a significant differe... |
