采用超声回弹综合法进行立井井筒砼强度的测试，得到实测矿井井壁结构上的实际砼强度，为井壁的加固设计及极限承载力的验算提供依据。
Ultrasonic rebound method was used to test the concrete strength of vertical wellbore, and the actual concrete strength of the measured shaft wall structure was obtained, which provided the basis for reinforcement design and ultimate bearing capacity verification of the wellbore.
