The application of fabricated segmental lining in deeply buried inclined shafts in complex strata has been significantly increased in recent years. However, the structural safety of the fabricated lining is vulnerable to high ground stress and high water pressure, as well as the vibration of mechanical equipment and ground disturbance caused by coal mining. Thus, applying an automatic load-monitoring system to the inclined shaft in coal mines has great engineering importance in evaluating structural safety. In this study, an automatic monitoring and data transmission system for the inclined shaft was developed. In addition, by considering the non-linear characteristics of segment joints and different working states of concrete segments, a more functional assessment method was proposed based on the limit state assessment theory. According to the in situ monitoring project in the number 2 inclined shaft of Bulianta coal mine in China, the calculated internal forces are in good agreement with the monitored data, and the proposed assessment method shows reliable results during the operation period.

煤矿斜井原位自动监测与工作状态评估

近年来，装配式管片衬砌在复杂地层深埋斜井中的应用显着增加。然而，装配式衬砌的结构安全易受高地应力和高水压以及煤矿开采引起的机械设备振动和地面扰动的影响。因此，将自动载荷监测系统应用于煤矿斜井对结构安全评估具有重要的工程意义。在这项研究中，开发了一种斜井自动监测和数据传输系统。此外，通过考虑管片节点的非线性特性和混凝土管片的不同工作状态，基于极限状态评估理论，提出了一种更具功能性的评估方法。
