摘　　要：为了能够快速准确地判别煤矿突水水源,提出了基于激光诱导荧光(LIF)技术的煤矿突水水源监测方法,该系统以MC9S12XS128B微处理器为核心,构建了共聚焦式检测子系统,通过USB2.0协议实现硬件采集系统与上位机通讯的方案。通过对反馈回的激光诱导荧光光谱进行分析,可以定量分析煤矿水源中水质离子的浓度,因此就可以实时监测到突水水源的变化。该方法克服了传统方法无法实现对大面积水域的实时在线监测的难题,能准确快速地得到结果。本研究可进行煤矿未知水样的水源判别,为煤矿的安全生产提供决策依据。In order to quickly and accurately determine inrushing water source in coal mines, inrushing water source monitoring method based on laser induced fluorescence （ LIF ） technology was proposed. The system u- ses MC9S12XS128B microprocessor as the core to build confocal detection subsystem, and communication solu- tion of hardware acquisition system with host computer is realized with USB2.0 protocol. On the basis of fed back laser - induced fluorescence spectroscopy analysis, quantitative analysis of water ion concentration can be done, real - time monitoring of inrushing water source changes can be realized. By use of the method it was solved that the problem with traditional method, by which large area of waters can not be monitored in real time and on line, and monitoring results can be got accurately and quickly. The method can be used to discriminate unknown mine water source, which provides a decision - making basis for coal mine production safety.
