Industrial resources of 124 types of different mineral raw materials have been developed at the Bulgaria territory and considerable base for development not only mining industry but also for branches of national economics, connected with it at the territory of Bulgaria. Important part of resources and stocks of metallic mineral raw materials has been characterized with low content of useful minerals, therefore conventional methods of extraction are not provide acceptable economical efficiency. But in the country as in the world, new methods of stock and mineral resources development, using physical-chemical geotechnologies, in particular, have been developed.
