Basic mineral wealth was brown coal deposits of Moscow Coal Basin in Tula Region until recently. Mining brown coal deposits of Moscow Coal Basin was begun since 1853. More than 1 milliard and 200 million tons of coal were mined that time. Summarized area which somehow or other undergoing anthropogenic influencing connected with mining coal deposits is equal about 12 % from common territory of the region. Liquidating mines in the territory of Tula Region created environmental problems. Negative influencing liquidated waste dumps continue upon all components of environment until our time. There are more than 250 million tons of rocks on the earth surface of different forms of mining industry wastes. Integrated environmental model of waste dump is proposed which can be basis of physical models for migrating pollutants processes and their mathematical description. It’s shown that intensity of mass exchange processes between the waste dump and environment as a rule is identified by environmental and geotechnological periods of waste dump existing on surface industrial area of a mine. Under such conditions liquidating the mine doesn’t signify liquidating the waste dump and the one can function as sludge liquor source during a lot of years. Mathematical model of vertical migration a pollutant into soil on base of onedimensional equation of convective diffusion with taking into account sorption kinetic of the pollutant by solid phase of soil and rocks is proposed. Calculating experiments were realized and it’s established that migrating toxic sludge liquor from waste dump surface result in polluting soil and underlying rocks. Vertical concentration profile has wave-like nature with point of maximum which stipulating velocities balance of convectivediffusion transfer and sorption processes at the moment of time in concrete point of considering space.
