Fiber Optic Sensors Materials based Spontaneous Combustion Detection in Goaf Areas

摘要

The main objective of this paper is to provide a possible monitoring system, which includes multiple sensors such as fiber optic temperature sensor, gas sensor and differential absorptive methane optic fiber sensor. Optic fiber sensors offer a number of unique advantages for safety monitoring in explosive and hazardous environment of the underground coal mines. The application potential and future trend of optic fiber sensors for coal mine hazard detection and prevention are discussed. This paper also researches on the prediction methodologies such as spontaneous combustion tendency prediction method, factors judgment prediction, experience statistical prediction method and mathematical models based on coal layer conditions, mining methods, and goaf areas. The combination uses of fiber optic sensors and prediction models are helpful to increase the safety of coal mines.
