LIF technology in the application of mine water inrush monitoring and warning system

摘要

This paper mainly describes the basic principle of LIF technology and its application in mine water inrush monitoring and warning system, emphatically analyzes the structure of LIF technology and design of the main components.Through the fluorescence experiment with the water samples of one mine in the LIF system, we can get the fluorescence spectra of the unknown samples.Traditional water source identification mainly according to the ion concentration representative of the water, but it is hard to analysis the ion concentration of the water from the fluorescence spectra.This paper proposes a more simple and practical methods for the precise water source identification by fluorescence spectra, which corresponding analysis software is used to measure the Euclidean distance between unknown water samples and standard samples, and then we can get an accurate classification of the unknown samples.Water source identification for unknown samples verified the feasibility of the LIF system, and solve the problem that the current coal mine can't have a better real-time and online monitoring on water inrush,which is of great significance for coal mine safety in production.
