Some features of the construction of baths

As you can see, with the use of a chamber -cutting system, a part -time job was carried out by mountain work on the layer of Verkhnyaya Marianne – a complex of buildings on the street. Amangeldy. Although, due to the mass collapse of the covering thickness of the current, the considered section, due to improper conduct of bailiff work, was not able to identify the efficiency and optimal parameters of the system in terms of protection of structures, this experience has proved the possibility and feasibility of using such a system of coal reserves within the safety whole buildings for capital buildings and structures.

This conclusion is also confirmed by the experience of working out safety columes on the layer of Verkhnyaya Marianna – 2 under the industrial site of the Stakhanovskaya mine and the complex of buildings on the street. Mayakovsky Kirov district a chamber system for the project developed by books. As shown by instrumental observations conducted by the sector of the shift of the Kazakh branch under the leadership a. S. Murashev, the greatest effect was achieved with the ratio of the width of the chambers and width of the entire number 1: 2, which ensured the smooth nature of the move of the thickness of the rocks with a slight manifestation of deformations of the earth’s surface.

Attempts made in the pool attempts to protect the processed structures by increasing the speed of the treatment of treatment plants – the building of school No. 2, the central stadium of the miner – did not give positive results, since with the coal technology existing in the basin, which ensures the rate of treatment with up to 60 mmes, and the depth of mining, and the depth of mining more than 200 m of a noticeable improvement in the deformation regime of the earth’s surface does not occur. Moreover, an increase in the rate of progress of treatment plants with the base of the developed structures of dense soils characterized by a high deformation module can adversely affect the outcome of their part -time work. Thus, the authors of the study of the nature of the redistribution of soil rebuilding on the sole of the foundations of the developed large -panel houses on the shaft field. Kostenko showed that with an increase in the rate of the process of moving the earth’s surface, the intensity of the redistribution of reactive rebuff of the soil increases and, as a result, additional efforts acting on the buildings increase.
