| Summary: | In the article a fiber-optic method for monitoring rock
pressure is considered, as well as the magnitude of the
displacement of the layers of the stope hanging wall is
measured. The authors analyze the applied rock pressure
testing methods. The reasons for the need to create a
safe system are given, the main requirement of which is
the condition of compliance with all safety requirements
during mining operations. The developed quasi-distributed
fiber-optic system is capable of measuring with high
accuracy changes in rock pressure and displacement of
roof rocks in an explosive environment, also does not
require expensive equipment associated with the use of a
range of analyzers and reflectometers. A scheme has been
proposed to simplify the testing process. The results of
dependences of additional optical losses on the applied
force are obtained. |
