The development of bauxite deposits in the North Onega region by open pit mining has required the creation of significant external dumps. Currently observed deformations on the dumps reduce their capacity, reduce the efficiency of utilization of the areas allocated for dumps, complicate the system of mining.

In the open-pit method of bauxite mining at the quarries of the Tikhvin Alumina Refinery, as a result of erosion by surface and underground waters of sandy-clay and bauxite rocks that make up the ledges of the sides, working platforms, dumps, as well as the bottom and walls of drainage ditches, there is pollution of mine water.
