INTEGRATED METHOD OF DIAGNOSTICS OF CONCRETE LINING AND CLAMPING SPACE OF MINE SHAFTS Russian patent published in 2017 - IPC G01V1/00 

FIELD: mining.

SUBSTANCE: method of complex diagnostics of the state of concrete support and fixed space of shafts includes visual studies of the walls of the support, cleaning of the supports from the salt build-up, georadiolocation, ultrasonic studies, drilling of exploratory holes and the repayment of cavities in the anchorage space. Initially performing the geo-radiolocating diagnostics of lining with data binding to the results of the single ultrasonic sounding. Ultrasonic sensing is carried out on a frequency of 25 kHz. Then, the sites for detailed work are determined, which are carried out on a thickened network of georadar profiles using an area ultrasound tomography with a frequency of 60 kHz.

EFFECT: enables the identification of cavities in the clamping space of mine shafts, as well as reducing the power of concrete lining by complexing non-destructive testing methods without the drilling operations.
