The problems of development geotechnological methods: Mastering Shemraevskogo BZHR field. As promising geotechnology Flow diagrams providing preservation Earth's surface, the unique black soil, water resources, environmental and industrial safety, high profitability of iron ore a new qualitative level.

Lighted material on crop, mostly in the Vologda region. Provides information from 1913 to 2005 inclusive.

The book presents the results of a numerical method for the study of the stress-strain state of the mountain of rocks and developed software to solve technological problems geomechanical and underground mining of minerals. Methods for submission, processing and interpretation of the results of the calculation of the stress-strain state of the rocks. The results of studies and calculations of stress-strain state for a variety of mineral deposits. The examples of the geological conditions of copper, polymetallic, iron ore solved problems of geomechanics process for assessing the strength and stability of the structural elements of advanced systems development. The book is intended for scientists and engineers mining institutes and may be useful for students enrolled in the direction "Mining".

We consider the scientific, technical, environmental, and methodological aspects of the development of large deposits of deep watered rich iron ore KMA. The book presents the results of studies structural features, material composition, physical and mechanical properties and the evaluation of the variability of rich iron ore, geomechanical processes in hydraulic borehole. Calculations of the stress-strain state of the ore array simulated formation of zones of displacement and destruction in the ore with hydraulic borehole array and the new proposed geotechnology. The concept and development of geotechnology rich iron ore deposits of the KMA. The book is intended for scientists and engineers mining institutes and may be useful for students teach-ing in the direction of "Mining".

German scientists say that the last time the Earth's pole switch places not 780 thousand years ago, and much later, in the time of Homo Sapiens. However, nothing terrible has happened for some reason ...

At the end of September in Kiev Podol opens an unusual museum of popular science and technology.

Accident at the mine workings - a thing constant. The new device is now being tested in the UK, will help in real-time tracking of the status of each miner, on time learning about the incident and, therefore, without delay, begin rescue operations.

Heavenly Guest 30 km in diameter hit the Earth about three billion years ago, creating a crater that was once a depth of 25 km and 600 km wide.

Report of the National Research Council of the United States posits: hydraulic fracturing is used in the extraction of shale gas is probably responsible for a series of small earthquakes in the East, the United States. But their strength is small, and the danger should not be exaggerated.

The reason for the magnetism of the planets and the possibility of changing the poles of meadow.

Carbon dioxide, volcanoes erupted Permian period, would lead to substantial changes in marine chemistry. Today, in fact, there is the same, but for man-made reasons.

A major earthquake is not just wipe off the face of the earth kind of town. It will destroy a vast infrastructure of oil production, which depends much of the world's population.

A rough estimate based on geological evidence suggests that the chance of a new eruption of the Yellowstone volcano in our lives is 1:10 000. However, in reality, given the volatile nature of the volcano, it means nothing. Pocket of magma can erupt at any moment!

or oil and gas industries Arctic Ocean - the last hope. Beneath it rest for about 90 billion barrels of recoverable oil reserves - about 13% of the world. As sea ice retreats, and other hydrocarbon deposits are depleted, the hope is that this cup pass from the Arctic, shrinking with each passing day.

Geological studies on the development of criteria for the valuation of the ecosystem can objectively assess the state of the environment and the changes occurring in it at the stage of development and exploitation of oil fields in northern Russia.

Under the oil and gas strata understood Association paragenetically related species, some of which contain oil and (or) gas. In recent years, to describe the association of rocks, the term "oil and gas complex", meaning by it the association of species, including a porous body - Collector, and various screening sediments.

Patterns of distribution of oil and hydrocarbon gas are determined by stable bonds accumulations with some geological characteristics (structural zones and elements, litho-facies and the formational units, hydrogeological zones, geochemical environment, etc.). Placement of oil and hydrocarbon gas is subject to the principle of differential trapping hydrocarbons.

There is experimental evidence for that oil could be formed from the previously buried in the depths of the lithosphere of plant residues, but they first had to happen for a number of geochemical changes (hydrolysis of cellulose, the decomposition of protein, fat saponification, decarboxylation of fatty acids, etc.). The form of the original burial of OM largely determines the subsequent mechanisms and processes for its conversion to hydrocarbons (HC) of the oil line.
