| Abstract: | Mine workings advance in surrounding rock will make stress redistribute,resulting in loose circle. Grasping the range of the loose circle may avoid blindness of support. The working principle and method of using the ultrasonic technology to measure the loose circle of the roadway surrounding rock are expounded. |
