Reproduction of power resources as ecological problem
Abstract
The attempt was taken to analyze technogenic reproduction possibility of hydrocarbonic energy crude in lithosphere by recycling domestic and industrial drain (fluids). This attempt was based on hypothesis of organic nature of fossil fuel.

Experimental researches on extraction of manganese from mining waste of concentrating factory
Abstract
In clause results of the integrated laboratory researches on extraction of manganese from mountain waste of concentrating factory are resulted. The technique of experiment is resulted. Influence of concentration of a sulfuric acid, time of experience, parities «firm» : «liquid» and the charge of sulphurous gas on process of extraction of manganese is proved.

Mineral resources and economic safety
Abstract
As the world experience shows mineral resources play the key role in economic safety of developing countries. If a government controls economy effectively, a significant role of mineral resources will be maintained. From the other hand, much mineral resources neither make economic growth nor economic safety.

Application and analysis of right helicoidal shells
Abstract
Drilling machines with drilling elements as helicoid are widely used while making of drilling auger, round section testpit and so on in crust for exploration of geological structure, searching, prospecting, minerals extraction, engineering geological research. Helicoidal shells can be designed as right, inclined, open and wrong-unfolding. There are main thesises of calculation method given by V.G. Rekach for right helicoid.
