The article presents the results related to developing and practical testing the method of monitoring the stress-strain state of steel structures of mine hoisting machines. Certain positive properties of optical fibers make it possi-ble to use them for measuring the stress-strain state of steel structures. An optical fiber of the ITU-T G.652.D stan-dard is used as a sensor. The analysis and review of the current state of development of fiber-optic conductors is performed. The proposed method of non-destructive testing the stress-strain state of metal structures is capable of providing continuous measurements in real time. The proposed method is universal and suitable for monitoring the stress-strain state of any metal structures subject to fatigue failure.
