In particular, the quantitative fluorescent tracer experiment method is applied to the research direction of karstology. The total area of karst regions in China is approximately 3.44 million square kilometers. In addition, due to climate and tectonic effects, karst landforms, such as underground rivers, conduits, sinkholes, and karst trenches, are very likely to be formed. It is difficult to discover underground rivers and conduits that are below the terrain surface, resulting in a huge safety risk during underground construction such as tunnel excavation and limestone mining. Severe property losses and severe casualties may be caused.
The quantitative fluorescent tracer experiment provides an effective means for studying karst conduit flows and features of conduit structures. The existing fluorescent tracer system used in the field has many shortcomings and defects such as a short battery life, undiversified collected parameters, inconvenience in reading data on site, and a non-objective calculation result. In addition, the traditional fluorescent tracer system cannot obtain a flow capacity of a water body.
