基于光纤光栅传感技术的矿井结构监测

Structural Monitor of Coal Mine Based on Fiber Bragg Grating Sensing Technology

随着煤炭的深部开采,地应力的变化规律更加复杂,给煤矿带来的危害隐患日趋突出。本文利用光纤光栅传感技术的应变测试功能,介绍了其在深部矿井结构健康监测中的可行性和优越性。板集煤矿副井马头门结构健康监测实例表明:光纤光栅传感技术可以及时识别监测结构的受力状态,对可能出现的灾害提前预警,提高煤矿生产的安全性。

With the deep coal mining, rvariation of stress has become more complex,which brings hidden trouble to the coal mine is becoming more and more prominent.Strain test function by using the fiber grating sensing technology, this paper introduces its feasibility and superiority in structural health monitoring of deep mine. The structural health monitoring example of subsidiary shaft ingate of Banji coal mine showed that: fiber bragg grating sensing technology can identify the stress state of the structure,give an early warming to the possible disasters, and improve the safety production of coal mine.
