Development of theoretical and methodological background for mining regions' economic security

The paper reviews geoecology as a science of lithosphere and biosphere interaction regarding socioeconomic human activity. Such interaction is more likely to take place when using mineral raw resources. This is characteristic of Urals Mining Complexes being a basis of region's economy. The place of geoecology in ecological science is specified. The geoecology structure with its main science subdivisions is developed. Fundamental principles of geoecology as a scientific discipline are defined. The research methodology for environmental technogenic transformation by Mining Complexes is considered, as well as tools, structural principles, forms, ways and methods of scientific enquiry. The approach to geo-ecological research in mining complexes is worked out, including assessment of a targeted object, background and environment. The research brought about the assessment of natural and economic damage under the influence of a mining complex.
