Abstract
The technogenic load of enterprises of mining and mining and processing industries causing pollution of land and water resources and atmospheric air is assessed. Mining enterprises account for up to 80 percent of the volume of stockpiled wastes of all production complexes. Development of methods to assess the risk of impact of technogenic arrays on the environment is a very urgent problem, since it allows preventing or reducing the negative impact of technogenic arrays by targeted selection of the type and design of storage facilities for projected and existing enterprises, development of a set of measures to improve and rehabilitate disturbed lands. The analysis of landscape-geochemical situation formed under the influence of intensive technogenic load in the areas of waste storing was carried out, the processes of formation of halos and pollution flows were studied; the method of ecological hazard assessment of technogenic massifs was created, the method of economically expedient and safe storing of waste was developed.
