| Abstract: | This paper applies the ultrasound detection to deep hole in the tunnel floor at No.-625 vehicle stop No.3 pit of LongFeng Mine, Fushun.Mining Bureau,and decuced the relaxationring range of the area.The properties of the rock strata are analyzed according to the actual condition of drilling hole and the acoustic wave. Therefore, the important basis of the preventoin and treatment of the tunnel floor expansion is provided. Meanwhile, several problems about ultrasonic detection of the tunnel floor with soft rock are given, which must be paid attention to. |
