The article presents the results of a flow-through experiment simulating the process of dissolution of soils of the foundation of a dam of a hydraulic structure by groundwater. The object of the study is the tailing dump of the concentrating plant, during the operation of which the permafrost soils of the coastal abutments of the enclosing dam thawed, significant volumes of circulating water leaked into the shunting tank located below. The development of filtration channels in fractured tectonic zones that make up the near-rock massif does not stop. Upon completion of the experiment, which lasted 20 weeks, an array of measured parameters of solutions at the exit from the columns was obtained: pH, specific conductivity and elemental composition. The data obtained made it possible to estimate the rate of dissolution of the soils of the dam foundation.
