1. System Overview

Detecting mine roof and surrounding rock is a key component of mine disaster prediction. Mine roof falls and surrounding rock collapses are among the most severe disasters in all types of mines, severely threatening mine production safety and causing significant economic losses and casualties. In recent years, with the continuous extension of tunneling faces and the expansion of mining areas, mine production has grown in depth, and the threat of roof falls and collapses has become increasingly severe, making prevention and control increasingly challenging. Mine roof disasters pose a serious threat to the lives of miners.

The fiber-optic roof safety dynamic monitoring system utilizes advanced fiber-optic sensing technology to provide long-term dynamic monitoring of roof fall conditions, anchor support stability and potential hazards, the impact range of advance support pressure, and the forward velocity of pressure, providing reliable assurance for safe coal mine production.

3. System Functions

1) Real-time online monitoring of coal mine roof delamination, anchor support stability, and lead pressure, with data transmitted to the surface server via an industrial ring network;

2) Features real-time data display, historical data comparison and analysis, threshold alarms, and trend alarms;

3) Cloud chart analysis of the lead pressure impact range provides data support for rock burst observation and analysis;

4) Flexible working face footage editing allows for close integration of monitoring data with mining conditions;

5) Daily, weekly, and monthly report printing for convenient management Management personnel conduct technical analysis and summary.

4. System Features

1) Fiber optic cables are used for data transmission, and front-end sensors require no power, making the system intrinsically safe. The optical signal is immune to external electromagnetic interference and exhibits minimal long-term drift.

2) High multiplexing capability: Multiple sensors of varying types can be connected to the same optical fiber core, enabling continuous monitoring of multiple points in a single line, a two-dimensional array, or spatially distributed data.

3) The system consists solely of an intrinsically safe fiber Bragg grating (FBG) interrogator, an intrinsically safe power supply, fiber optic sensors, and communication cables, resulting in a simple, reliable, and easy-to-maintain structure.

4) The system monitors large amounts of data, provides highly reliable trend analysis, and exhibits strong self-learning capabilities.
