Preliminary Estimate of the World Reserves of Aquatic Gas-Hydrate Accumulations
The authors describe the present state of and predict the world consumption of the energy resources for the period until year 2020. The limited and non-renewable nature of the traditional resources of natural (combustible) gas and the growing demand for this energy carrier in the 21st century force the mankind to pay attention to its significant reserves stored in non-traditional sources, first of all in the natural gas hydrates. According to the present-day geological knowledge, huge amounts of hydrocarbon gas are stored as solid gas-hydrate deposits in sea and oceanic bottom sediments. E.g. potential reserves of methane in gas-hydrates are estimated as 2×1016m³. By now over 220 gas-hydrate deposits have been discovered on the bottoms of seas, oceans and large lakes. It has been found that about 98% of those deposits are concentrated on the shelf and continental slope of the World ocean (off the coasts of North, Central and South Americas, North Asia, Norway, Japan and Africa, as well as in Caspian and Black seas) at depths over 200-700 m, and only 2% are located in polar regions of continents.

Improving the quality of subsoil resources exploitation as a way to reinforce the mineral and raw material base of the mining practice
The authors consider the issues of improving the efficiency of traditional underground ore mining techniques. They conclude that key determinants of the production profitability are quality factors, namely losses and dilution. It has been found that quality factors of subsoil resources usage, work productivity and an enterprise's productive capacity are parts of equivalent correlations which provide the basis for managing the fullness of the subsoil resources exploitation. The authors demonstrate that the dilution value reduction in the course of traditional mining techniques upgrade is an important way of improving the mining practice efficiency.

The rework of mineral deposits as an aspect of improving the efficiency of the mining practice
The author provides historical and bibliographical data on combined exploration of mineral deposits. Using the example of sequential underground and open-pit mining at Zlatoust-Belov mine (Zhezkazgan deposit, Kazakhstan) she proves the feasibility and the effectiveness of reworking the deposits.

On conditional and ambiguous nature of cost allocation for iron-ore mining and processing
The authors point out the ambiguous nature of cost allocation to the production, which requires performing additional economic analysis, as shown by the authors in the case studies of the mining production at iron-ore industry. The authors conclude that the ambiguousness in cost allocation can lead either to insignificant and non-essential deviations in determination of production cost or to serious miscalculations causing strategic mistakes during exploration of mineral deposits. In view of this, it is believed that solution of the problem specified in the article will contribute to preparation of the new and adjustment of the existing standards, rules and guidelines in the area of subsoil resources usage and natural environment protection with consideration of the world's best practice.

Predicting the seismic transients velocity during the design and firing of coyote blasts in open-pit mines
The authors provide the fundamentals of the method used for predicting the seismic transients' velocity during blasts firing at a number of open-pit mines producing non-ferrous metals. They also provide a case study of calculation of seismic transients' predicted velocity when blasting one or more blocks.

Geological indicators of assessment and prediction of mineralization during mineral deposits exploration
The author considers the feasibility of local prediction of ore bodies based on the geoindicational modelling. As the basic criteria he suggests using the technological grade geoindicators for kimberlite ores and dwells on the mineralogical criteria of gold mineralization of pyrite.

Emergence and development of geology as an Earth science studying its mineral wealth
The author demonstrates the evolution of knowledge, geological hypotheses, concepts and theoretical models related to the Earth development history, the origin and geological structure of mineral deposits – from high antiquity to the modern scientific ideas. He provides the chronological sequence of the theories and discoveries by the outstanding scientists in the field of constitution of earth, crustal structure and the origins of metallic and non-metallic deposits.

The oriental footprint of the ancient geodesy
The author notes that the ancient culture, and geodesy as its part, had spread much farther eastwards that it was believed earlier. The ancient Greeks have inseminated the Indian culture, built ties with China and laid the groundwork for the future science development in the East. As to mapping and geodesy, the ancient influence led to creation of the maps of at least the same accuracy and realism as the best maps produced in the Roman Empire. If Byzantine Empire is considered to be the successor of the ancient geodesy in Europe, then India, though in a smaller amount but still reasonably, can be regarded as the successor of the ancient geodesy in the pre-Arabic East.
