The present-day micro-climatic conditions in black coal mines are of such nature that in no mine natural micro-climate conditioning is sufficient any more. The original temperature of rocks grows progressively in dependence on the increasing depth of

Karst manifestations are widespread in many regions and pose a significant danger to residence and economic activity. Failing funnels arise during the collapse of rocks over underground voids (caves, workings, etc.), formed during karst formation or

The article is devoted to the applied problem solution of a continuous medium inelastic deformation as applied to the description of the heaving of rocks in the workings. This is the ubiquitous manifestation of rock pressure in workings, both in coal

The article deals with the description of the deformation regularities and the conditions for the transition of stable, quasi-static destruction of specific areas of the rock massif under its loading into the unstable one and catastrophic. The decisi

The main regularities of deformation and loading of the stook during creation of the developed space with the great area of a side job are considered in the article. The possibility of formation of the set of balance among the stook barriers is estim

Natural ventilation in a mine is ventilation without the use of means of artificial ventilation. The flow of mine air is induced by the difference between the mass column in an intake and that in a return. The difference in mine air density is a resu
