摘要
文中研究布里渊光时域分析技术测量相似材料模型采动过程中的覆岩应变。研究结果表明:分布式光纤传感技术能够高精度感知和反映沿光纤某一点处岩层在受到煤层开采影响时的应变变化,为相似材料模拟试验中岩层应变监测提供了一种新途径。
In this paper, Brillouin optical time domain analysis technology was studied to measure overburden strain during mining of the similar material models. The research results showed that the distributed optical fiber sensing technology could sense and reflect the strain change of rock stratum at a certain point along the optical fiber under the influence of the coal seam mining with high precision, which provided a new way for the rock stratum strain monitoring in the similar material simulation tests.
