Summary:Title screen
The topicality of this work is due to the importance of developing such a new-generation monitoring computer-aided measurement system intended for ensuring the safety of mining works and coal mining that would allow one to monitor all required parameters and defects in a massif. Additional optic-fiber losses have been investigated with the aim to develop the sensors of the computeraided measurement system for monitoring the technical condition of mining practice objects. Dependences between the number of deformed fiber sections and additional losses have been revealed for different wavelengths in the optical range; deformations and mechanical stresses in the optic fiber have been determined under stepwise pressure increase. Based on this data, a model has been proposed for an optic-fiber sensor intended for monitoring mechanical stresses in mine workings.
