摘　　要：陕西煤业化工技术研究院“矿井地质保障技术研发室”成功研制了基于显微成像技术的地下水流速和流向观测系统。该系统利用图像粒子跟踪测速(PTV)算法分析水中颗粒物质的运移速度,通过概率统计分析判别得到地下水最终的流速和流向信息,测量灵敏度高,无测量下限,该系统分为单孔测量版和群孔监测版。可以应用于水文地质勘查、开采活动中重大水体监测、突水溃沙灾害监测预警、滑坡灾害监测预警等多个跟地下水体相关的测量、监测、预警领域。The Mine Geological Support Technology Research Office of Shaanxi Coal and chemical Technology Institute successfully developed groundwater flow rate and flow direction monitoring equipment based on microimaging technology.The system uses image particle tracking velocimetry(PTV)algorithm to analyze the migration velocity of particulate matter in water,and obtains the final velocity and flow direction information of groundwater through probability statistical analysis.The system is divided into single hole measurement version and group hole monitoring version,which can be applied to many measurement,monitoring and early warning fields,such as hydrogeological exploration,major water body monitoring,and disaster monitoring and early warning.
