Gas and dynamic phenomena in collieries: the nature of an origin, methods of management and a way of decrease in dangerous displays
Abstract
Tectonics the broken natural carboniferous file is capable to generate gas and dynamic displays at infringement of its natural condition of balance during conducting mining works. The main source of forces initiating gas and dynamic displays, the high level of operating pressure in a power floor of a natural file is. Thus factors of reduction of parameters of durability of coal and breeds, growth of pressure of gas in emptiness tectonics the broken environment raise probability of displays of emissions a little. However they are subordinates and the share of their influence essentially depends on sizes of operating pressure in a power floor of a natural file. In borders of all area of the flat coal layer which has undergone tectonic infringements, in its natural power floor there is the non-uniform distribution of operating pressure caused mainly by presence of different levels of tectonic pressure. The most dangerous on gas and dynamic to displays are natural (natural) abnormal zones of the convex, concave forms and forms in the form of a saddle a layer with a gradient curvatures about 0,2-0,25 km-1 and more. Only in borders of area tectonic Infringement of a layer, including abnormal zones of a high level of pressure, with increase in depth of development frequency and intensity gas and dynamic displays increases.
The technogenic abnormal (basic) zones of the raised pressure formed at working off tectonics broken a layer, as a whole worsen geomechanical conditions of manufacture of mining works. In the developments subject to influence of technogenic zones, the degree of displays of mining pressure, however danger gas and dynamic displays essentially usually increases only within the limits of the area of joint action of a high level of pressure of abnormal zones of natural and technogenic origins. Now it is necessary to use at regional forecasting an available method of definition of places and borders of an arrangement of natural abnormal zones of high pressure in a power floor of a containing carboniferous file, giving greater practical importance tectonic Infringement of a layers in borders of a mine field, beforehand to predetermine and use the approved rational measures and ways of prevention or possible minimizing of danger gas and dynamic displays during conducting mining works.

Principles of restructuring of the coal industry of Georgia
Abstract
Shown that the currently adopted concept development Tkibuli-Shaori deposit (TShD) does not correspond to mining and geological conditions of occurrence of the coal strata of the deposit, provided trough-like. Each wing of the trough is being developed by several small mines, the geometric dimensions of the extraction pillars which does nor exceed 200 m, where the use of modern means of complex mechanization of coal mining uneconomical, that determines these unprofitable mines. The new concept of development TShD, which unlike existing delivers opening balance of reserves of the field with a sloping trunk pipeline delivery to the division of a single mine field into two blocks with long columns of 1500-2500 m for the effective application of mechanical complex that it maximizes the concentration of production and provide favorable conditions for intensive development of the field. As a result of subsidized coal industry of Georgia becomes profitable.
