Paper Abstract

Fiber optic sensors have become increasingly attractive for application in advanced intelligent coal mines, which consist of extensive sensor network to monitor the structural integrity, environmental safety and production parameters. Fiber optic based strain (mining pressure), temperature, water pressure, methane gas, seismic and ultrasound sensors can be used to monitor the condition of the coal mine and provide information for accident prediction and early warning. We report for the first time an all fiber optic comprehensive coal mine safety monitoring system. The system is capable of methane gas monitoring, temperature monitoring, seismic event and mine pressure detection and water pressure monitoring. The advantages of this fiber optic sensor system include intrinsic safety in explosive environment and multiparameter monitoring. The technology potentially can be used to replace many discrete and incompatible monitoring systems currently deployed in the coal mines and consequently greatly enhance coal mine safety.
