The anbalysis of the current state of the benches and walls of «Udachny» open-cast mine
The author provides the analysis of the current state of the benches and walls of «Udachny» ultradeep open-cast mine, In order to improve the accuracy of the underground surveys, along with the current method using the GPS satellite positioning equipment it is advised to simultaneously observe the reference checkpoints using the traditional measurement devices. The underground surveys must be followed by the documenting of the mine rock position as of the moment of observation, which will allow to ascertain the reasons of the deformations being observed.

The transition of the stressed-strain state of the periphery massif in the process of the roadway bolting
The author shows that observance of the operating procedures is one of the most important factors for the successful use of roof bolting. In order to investigate the influence of time and distance from the bolts to the mine face, the author provides the calculations for three process flow diagrams. The analysis of the obtained data allowed to make a conclusion about considerable influence of the lag between the bolting and the mine face upon the subsequent deformation of the anchors and peripheric solids.

Basic ways of aquatic gas-hydrate accumulation
The authors characterize the conditions of aquatic gas-hydrate accumulation and describe the factors affecting the deposit size and the thickness. They have found out that the sources of the organic matter (which subsequently transforms into methane) for the formation of the gas-hydrates are rivers, fractures, mud volcanoes, gas flames, hydrothermal waters and other objects. A significant amount of marine (lake) methane is produced by microorganisms. An important role is played by the emission of hydrocarbon gases from the bottom sediments.

Evaluation of the completeness of exploration and forecasting the degree of disjunctive disruption of coal strata
The authors have found the dependence between the ratio of the actual disruption of coal stratum to that predicted by prospecting and the criteria values of the extent of exploration of its hypsometry. They demonstrate that the use of such a dependence allows evaluating the actually expected stratum disruption based only on the exploration data.

The influence of the softening zones on the development of deformation processes in the rock mass and on the ground surface
The authors analyse the feasibility of applying the mining method using the softening zones by the example of mining a deep-laid potash seam located under the bodies of water. They consider the influence of the softening zone on the development of the deformation processes taking place both in the rock mass and on the ground surface.

Improvement of technical means and man-induced alluviation massifs condition evaluation methods
The authors consider the preconditions, the lines of development and the ways of improvement of the geotechnical sampling network density and the technical means of hydrogeomechanical monitoring of the technogenic solid masses. They point out the shortcomings of the remote monitoring systems used at the tail dumps by the mining enterprises of the Kursk magnetic anomaly region and propose
a number of corrective measures.

Legal regime of prospecting and exploitation of mineral deposits abroad
The authors give individual examples of the legal regulation of the relations arising from granting of the right to use subsoil resources, regulation of the rights and obligations of the parties of business activity is the course of subsoil resources usage, as well as termination of such right, including conservation and closing down of mining enterprises in certain foreign countries. They point out the specifics of the legal regulation of economic operations during subsoil usage and the legal regime of the mining enterprises.

Survey gyrokompass PGO-1
Based on the past experience, the authors believe that PGO-1 gyrocompass is the most efficient tool for mine-surveying work in mine openings with high rock-pressure manifestation for cutting the underground theodolite traverse. This gyrocompass allows taking the azimuth when used in combination with any theodolite.

Certain aspects of geodesy during the Renaissance
The author proves that the development of geodesy during the Renaissance was closely related to the discovery of Africa, the New World and Australia. The maps of the world become popular that contain accurate representation of the Mediterranean and the Black seas along with approximate and inaccurate outlines of Africa and the New World. The maps are supplemented with the geographical grid; map projections and a unified scale are used. The appearance of the new mathematical symbolism in geodesy without doubt meant great progress.
