摘　　要：本文主要叙述LIF(激光诱导荧光光谱分析)技术的基本原理以及在水源识别中的应用,重点分析LIF技术的系统构成和主要模块的选择设计。通过该系统对某矿的送检水样和标准水样进行荧光实验,得到水样的荧光光谱图。传统的水源识别主要依据水中代表离子的离子浓度进行分析,但是从荧光光谱分析水中代表离子的离子浓度难度较大。本文提出一种较为简单且实用的方法由荧光光谱进行水源的精确识别,即使用相应分析软件分别测量未知水样与标准水样的欧氏距离,得出未知水样的精确分类。对未知水样的水源识别验证了该系统的可行性,解决了当前煤矿无法对突水情况进行实时在线监测的难题,对于煤矿的安全生产具有重要意义。This paper mainly describes the basic principle of LIF technology and its application in water source identification,and analyzes the structure of LIF technology and design of the main components.Through fluorescence experiment with water samples of one mine in the LIF system,the fluorescence spectra of the unknown samples was obtained.Traditional water source identification is mainly based to the ion concentration representative of the water,but it is hard to analyze the ion concentration of the water with the fluorescence spectrum.This paper proposes a more simple and practical method for precise water source identification with fluorescence spectrum,which corresponding analysis software is used to measure the Euclidean distance between unknown water samples and standard samples and then get an accurate classification of the unknown samples.Water source identification for unknown samples verifies the feasibility of the LIF system,and solves 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.
