摘要

光纤传感器因其抗电磁干扰、耐高温、耐腐蚀等优点，被广泛应用于复杂环境下的长期监测。针对深部开采对支护结构稳定性带来的挑战，传统的电动测量螺栓系统存在电磁干扰大、安装复杂等缺点，迫切需要更可靠的监测技术。本文提出了一种矿用光纤布拉格光栅锚杆传感器技术。将布拉格光栅链连接并嵌入锚杆中，解决了表面安装光栅锚杆不能重复使用、易受环境影响等问题，具有实时、长时间监测锚杆受力状态的能力。通过对布连塔煤矿12511工作面端头锚杆和全锚螺栓的轴向力监测发现，端头锚杆本体的平均轴向力为77.24 kN，全锚螺栓的平均轴向力为67.90 kN。端头锚杆的轴向力是全锚杆的 1.14 倍。对于破碎的煤炭，全锚栓显示出更高的可靠性，为矿井支护设计提供了参考价值。

Bolt axial force monitoring based on fiber grating technology

Optical fiber sensors are widely used in long-term monitoring in complex environments due to their advantages of anti-electromagnetic interference, high temperature resistance and corrosion resistance. In view of the challenge of supporting structure stability brought by deep mining, the traditional electric measuring bolt system has the disadvantages of electromagnetic interference and complex installation, and more reliable monitoring technology is urgently needed. In this paper, a mine-used fiber Bragg grating anchor sensor technology is proposed. The Bragg grating chain is connected and embedded into the anchor rod, which solves the problems that the surface-mounted grating anchor rod cannot be reused and is easily affected by the environment, and has the ability to monitor the stress state of the anchor rod in real time and for a long time. Through the monitoring of the axial force of the end anchor and the full anchor bolt in the 12,511 working face of Bulianta Coal Mine, it is found that the average axial force of the end anchor body is 77.24 kN, and the full anchor is 67.90 kN. The axial force of the end anchor bolt is 1.14 times that of the full anchor bolt. For broken coal, the full anchor bolt shows higher reliability, which provides reference value for mine support design.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
