Movement of the earth’s surface Ukrinvestbud

Thus, we can talk about an attempt to rational planning of mining to reduce deformations of the earth’s surface.

To monitor the displacement of the earth’s surface and the development of deformations in the buildings, a special observation station was laid, consisting of a network of soil and wall reperttures. According to the measurements, horizontal deformations near the building of the clinic and the surgical corps amounted to 1,9 and 2.1 mmm, and the curvature radius is 8 and 14 km.

During the entire period of part -time, significant violations of the operating mode of buildings were not noted. In that part of the building of the clinic, which adjoins the transitional corridor, and cracks appeared in the fencing of the transition corridor with an opening of up to 15 mm. In the same building there was a protrusion of part of the end wall on the second floor under the influence of the designs of the transitional corridor, the skew of window frames and cracking of glasses in adjacent rooms. In the lobby, the bloating of the Metlah tiles on the floor was noted, the disclosure of cracks in the deputy ray jumper, peeling of the plaster to deputy stucco extensions increased to 5-6 mm.

The nature of damage in the building suggests that they are caused by deformations in the compression zone. When planning mining, it was assumed that the building would be in this zone. Therefore, the bulging of the end wall under the influence of the structures of the transitional corridor could be foreseen, since the deformation seam between the structures of both weapons was practically absent.

In the building of the surgical corps, the appearance of vertical cracks in the walls of window openings and on the conjugation of structures was noted. The disclosure of these cracks is 2-3 mm, and in some cases, up to 8-10 mm. The poor -quality execution during the construction of the building of plastering on ceilings (thick primer elephant on reinforced concrete flooring even without a notch of its surface) during the part -time period led in some cases to exfoliation and collapse of the plaster from the ceilings.

In the building of the therapeutic corps, no damage was manifested.
