Advance in tracer transfer regulation and research method of dewatering and tracing test in coalmine

Based on correlation theory of groundwater dynamics, the way to the quantitative analysis of time-varying data on flow, water level, and solute concentration, obtained in dewatering and tracing test, with solute transfer model is put forward. In addition, the basic rules of solute transfer in fissure medium and numerical solution for solute transfer model are systematically summarized, advantage and disadvantage of different numerical solutions and their applicable conditions are compared, and the process of building solute transfer model is discussed from the view of applications.
