The development of fiber optic Bragg grating sensors and their applications to the mine water-inrush model test

• 摘要：

  Fiber Bragg grating displacement, stress, seepage pressure and temperature sensors were developed based on Fiber Bragg Grating (FBG) technology. These sensors have the characters of small size, high precision, stable performance and reliable data-collecting which completely satisfy the need of the real-time date-collecting under the condition of water inrush. The sensors were pre-embedded in the key positions of the model, and the real-time monitoring for multi-field information was successfully realized through the entire process of water inrush. The experimental results not only reveal the precursory characteristics of mine water inrush, but also verify the validity and feasibility of these optical sensors in the water-inrush model test.
