Abstract To identify groundwater recharge and migration rules and guide the grouting treatment design and construction of water gushing underground engineering,tracer experiment for the hydraulic characteristics research of large area is introduced into the gushing-water underground engineering control. Base on the ultraviolet spectroscopy scanning method of low concentrations of colored tracer and data analysis technology,acquisition method of hydrological information(hydraulic connection time,the correlation coefficient of recharge,fracture space volume,groundwater flow rate and pressure) is proposed. According to the analysis of the tracer experiment result,choice of grouting material and determination of the grouting parameters can be put forward. Taking an iron ore for example,tracer experiment(application methods,data processing and application results) in gushing-water engineering control is described detailly,which is supposed as a reference to similar engineering.
