It is noted that the role of the government in the markets of the countries acceding to the WTO reduces (in compliance with all agreements relating to fair competition) while the role of independent and state regulators on behalf of certification bodies increases. The authors think that the WTO accession won’t affect fuel and mineral resources part of export in Russia as there are no serious limitations for sale of mineral resources in the world markets. Under the condition of the accession to the WTO it is proposed to develop economic incentives for companies of the mineral resources sector in order to diversify production and implement innovations.

Mining evolution is divided on the three phases in terms of the physical and intellectual activity: 1) primitive, 2) mechanization or physical liberation, and 3) automation or intellectual liberation. These phases correspond to the three levels of the mining cognition: empiric, analytic, and information technology (IT). The transition to the third phase is going now and it will be finished by unmanned mining technology creation in the foreseeable future. So the development of the third generation’s mine design will be the important task.

Deep open pit walls design using rock mass stress-strained state
One of the main deep open pit mining problems is the wall stability for a long time. It is obvious that the basic area of stress concentration in deep pits is the lower edges of pit walls. We have been studying the possibility of reducing stress concentrations like these by means of the alteration of the open pit bottom part configuration. To do this, there was considered the shape with a smooth passage from walls to the bottom of the pit (by widening the berms in the lower part) instead of trapezoid shape. Calculations were carried out for deep open pits with a flat and rounded bottom across and along the strike of the ore body.

Geological and mineralogical research were conducted by the scanning probe microscopy and showed that in plagioclase pegmatites of North Baikal muscovite province the average thickness of the peristerites increases from early graphic zones to late trochlear zones and pegmatoid zones of pegmatite veins. The thickness reaches a maximum in the pegmatites of pegmatoid structure which contain large-crystalline muscovite. This regularity can be used for development mineralogical criteria for evaluation of pegmatite veins productivity at the large size muscovite source.

The study presents experimental results illustrating a certain tendencies in the change in physical and mechanical properties of the Vendian clay formations over depth. A comparative analysis of samples from different borehole intervals has arrived at significant coefficients of correlation for the parameters that characterize the degree of the clay water saturation, compaction, and consistency with depth (the elevation of the core-bore sample in the profile). The rock deformation and strength parameters also demonstrate a dependence on the depth. The deformation modulus and the shear strength of the clay increase with increase in the depth of sampling.

Structural approach to complex dynamic object fault detection and localization
- Authors:
- L. B. Poshekhonov
- M. Yu. Shestopalov
Is designed the approach to the task of complex dynamic object diagnostics on the basis of internal structures features structural analysis. Operational units and links fault symptoms are detected by means of the system transfer quality change control. The task of fault source localization is solved by mean of diagnostic model of topological rank, invariant to the operators classes of blocks and values of their parameters. Is given an example of solving the problem of fault detection and localization of nickel powder technological production process system error source.
