摘要
对立井井壁线型传感器铺设以及变形监测方法做了研究,并获得井壁竖向变形规律。研究结果表明:卡扣固定方式可有效解决立井井壁潮湿环境不利于光纤传感器粘贴的问题;采用线型准分布式光纤光栅监测技术,立井井壁随深度的变形可以精细化实时呈现;线型准分布式光纤光栅监测技术可以有效地用于立井井筒监测,为其安全运营提供数据支持。
A study was conducted on the linear sensor pavement in the mine shaft liner and the deformation monitoring method and meanwhile the vertical deformation law of the mine shat liner was obtained.The study results showed that the fastening fixed method could effectively solve the optical fiber sensor difficultly stuck on the mine shaft liner due to the damp environment.The linear quasi-distribution optical fiber and optical grating monitoring technology applied could finely and timely show the deformation with the depth of the mine shaft liner increased.The linear quasi-distribution optical fiber and optical grating monitoring technology could be effectively applied to monitor the mine shaft liner and could provide the data support to the safety operation.
