Principal technologies for prevention of natural dangers at coal mines
- Authors:
- Yuzef Dubinski
Modern mining of mineral resources to be the industry accepted by the society must meet the criteria for sustainable development. Work safety is its important element, which is a particular sphere in underground coal mines in the view of natural hazards occurring numerously, including the catastrophic failures. Among them are gas hazard, fires and rock burst hazard. The selected methodological solutions in terms of their recognition and technologies applicable for the actively combat of these threats, which are featured by high efficiency, have been pointed out.

Aspects in geomechanics and safety in exploration of solid mineral deposits
- Authors:
- A. I. Perepelitsyn
The paper deals with the aspects of safety in mining at the ore mine «Norilsk nickel», the Yakovlevsky iron ore deposit, the Verkhnekamsk potassium-magnesium deposit of salts. It was shown that with due account of state of mining at the objects related to the utilization of the Earth's interior, the normative-legal support of mining regulation in the field of geomechanics is rather actual and it requires researches into the activities of mining enterprises as well as in the control work carried out by supervisory bodies of Mining Supervision.

Influence of blocky-hierarchy structure of geological medium on the forming of natural and technogenic geodynamic fields in the North-West part of the Amur geoblock
- Authors:
- I. Yu. Rasskazov
- B. G. Saksin
On the example of the South-Argun uranium ore district of Zabaikalie consideration is given to the interaction of regional and local fields of stresses. The district includes a number of deposits prone to rock bursts. The performed analysis contains data on recent geodynamics of the explored part of the Amur geoblock as well as on geomechanical and geologo-structural materials of Tulukuev caldera and of Antey deposit. It is shown that with the use of the M.A. Sadovsky relationship the indices of local structural forms of a row are subjected to unified laws of deformation and fracturing. Conclusion was made that at the beginning of deposit exploitation the direction of action of stress field within rock mass conformed to regional one, and then it considerably changed under influence of large-scale mining operations.

In such situation it is essential to conduct very thoughtful system of diagnostics of crust fields with fluctuation deformation characteristics. For that purpose follow-up realization of three interconnected procedures must be conducted: detailed and measurement-assured monitoring (geodynamic test-area), complex several-variant interpretation of results of the monitoring and selection of different scenarios of possible negative contour, determination of the level of geodynamic risk, forecasting the environmental, social and economic consequences, and formulating strategies for preventive arrangements.

Systematization of factors to be considered in mine abandonment design
Subsoil is not just a source of mineral resources; it also serves as a burial site of industrial and domestic wastes, a storage place for oil and gas, and an environment for constructing underground facilities and creating preservations and nature sanctuaries. Subsoil area development is intensified and diversified with each passing year, exerting great influence on ecological systems and all their components. Special attention should be paid to terrain as upper facet of lithosphere, submitted to maximal impact of anthropogenic processes. Activation and emergence of natural and anthropogenic processes causes changes manifested in various combinations of negative events. Most important events include deformations of rock mass and land surface: exhaustion and pollution of ground and surface water, waterflooding and swamping of tapped sites, soil dehydration and salinization, air pollution, land site withdrawal from commercial circulation etc.
