The classification of resources and expected reserves of solid minerals and the reliability of their geological and commercial assessment
The features and corelations are discussed of solid mineral resources and expected reserves classifications accepted in economically developed western countries and Russia with respect to their geological study and commercial value. It is remarked that a single world classification is much needed in modern conditions of world economy globalization. It is shown that the classification of G. Vettweise (FRG) is best matched to the problem. The role of prospected resources reliability as a decisive factor in estimating deposits is substantiated. Introduction of risk coefficients is proposed to increase the reliability of geological and commercial assessment of prospected resources. The values of those coefficients should depend on the complexity of geological structure and the extent of exploration; they should decrease from earlier to later stages of deposits development

Geological exploration process principles
In spite of the great variety of useful mineral deposits, their prospecting in based on uniform principles: completeness of data, data reliability, making costs minimal and obtaining optimal results of prospecting.

Liability problems in the law system of subsurface use and protection
The regulations and problems are discusses of management responsibility, criminal liability and environmental responsibility in the legal regulations system of subsurface use and protection. The current state and the problems of civil-law disciplinary responsibility and property accountability in the system of legal relations were considered in the previous issue of the journal.

Ecologically clean technique of near-shore placer deposits development with the use of hydraulic mechanics.
The proposed technique of coastal placer deposit development with the use of hydraulic mechanization eliminates the drain of process water polluted with clayey dust matter at the expense of artificial sand make up of the coastal zone. This provides ecologically clean state of the coastal zone. The technique includes water jet and hydrotransport of overburden rocks to a special structure that is a hydraulic mine dump serving as a classifier. This dump is intended for drawing mud from the overburden rocks slurry and it provides natural separation of the slurry matter into sand and clayey dust to prevent the drain of the latter into the coastal zone. The efficiency of the technique is supported by test results in the quarry of Primorskoie amber deposit.

Stripping and preparing potassium horizon by the Production Association «Belarus'kaliy»
The method of stripping and preparing mine field is shown with the parameters of extraction fields and mechanized driving and removing complexes, allowing us to carry out extraction of minerals together with making mine workings towards the boundaries of mining field. This will favorably influence the time of mine payback.

The prognosis of coal beds dislocations with a break in continuity
The method of coal beds rupture tectonics was elaborated on the basis of the regularity established from data on mine fields prospecting and development. The application of the solution of the «Buffon needle problem» allows us to estimate the probable number of occurrence of undiscovered ruptures within a block or a plate.

The assessment of the error of coal bed hypsometric plan
The technique of expected error assessment of the bed hypsometry model made from geological surveying data is presented. The technique is based on the quantitative definition of the ambiguity of the model under consideration and its transformation into error. As a result of the assessment, a cartogram is produced of hypsometric plan reliability.

The assessment and prediction of the ecological condition of Novomoskovsk industrial area with the use of numerical methods
Combined studies of conjugated many-layered models of ground water filtration and migration of the central area of Novomoskovsk industrial region of an area of 1598 km² allows us to reconstruct the changes of the ecological condition of the ground water under the effect of technogenic loads, to carry our research and to predict such changes. Areas with favorable and unfavorable conditions of water supply were established, prognostic maps of the changes of the general mineralization levels were obtained for major water-bearing horizons, favorable areas for new water intakes were located.

Neutron activation test of apatite and fluorine-containing ores
The possibility is considered of fluorine-content test of apatite and fluorine-containing ores with the application of neutron activation method. It is shown that the use of neutron generator (En = 14 MeV) and Pu-Be radioisotope source allow us to determine fluorine content both in ore samples and in the flow, in conveyor.
