Subsoil is not just a source of mineral resources; it also serves as a burial site of industrial and domestic wastes, a storage place for oil and gas, and an environment for constructing underground facilities and creating preservations and nature sanctuaries. Subsoil area development is intensified and diversified with each passing year, exerting great influence on ecological systems and all their components. Special attention should be paid to terrain as upper facet of lithosphere, submitted to maximal impact of anthropogenic processes. Activation and emergence of natural and anthropogenic processes causes changes manifested in various combinations of negative events. Most important events include deformations of rock mass and land surface: exhaustion and pollution of ground and surface water, waterflooding and swamping of tapped sites, soil dehydration and salinization, air pollution, land site withdrawal from commercial circulation etc.
