摘要: 针对现有煤矿巷道顶板离层监测主要采用机械式顶板离层仪，存在观测不方便、误差比较大、数据实时性差等问题，设计了煤矿巷道顶板离层结构健康监测系统。该系统通过光纤位移传感器自动测量巷道顶板离层的位移状况，采用计算机监测巷道顶板离层结构的应变、位移等参数，评价离层结构的安全性，进而维护结构的健康。实际应用表明，该系统具有实时观测、误差小、效率高等优点。

Abstract: In view of problems of inconvenient observations, bigger error and poor data real-time performance existed in monitoring for coal mine roadway roof separation with mechanical device, the paper designed a structure health monitoring system for coal mine roadway roof separation. The system uses optical fiber displacement sensor to measure displacement condition of roadway roof separation automatically, adopts computer control program to monitor strain and displacement of coal mine roadway roof separation, and evaluates security of structure, thus safeguards the health of the structure. The practical application shows that the system has advantages such as real-time observation, small error and high efficiency.
