The objects of site No. 1, located in the northeastern part of the plant territory, were most influenced by the side-work. Observations made it possible to establish the following maximum deformations of the earth’s surface in this area: subsidence — 200 mm, slopes — 2.5 mm, horizontal deformations — 2 mm (with a distance between the benchmarks of 15 m), ledges — 3.5 cm. of the deformation area of the earth’s surface were: subsidence — 80 mm, slopes — 0.8 mm, horizontal deformations — 1 mm. The territory of the plant, as already noted, was exposed to deformations of the earth’s surface even before the start of observations. Calculations established that the maximum deformations of the earth’s surface, in effect before the start of observations (from 1949 to 1965), were: subsidence — 420 mm, slopes — 1.6 mm, horizontal deformations — 3.6 mm, ledges — up to 4-5 see It should be borne in mind that the question of determining the total deformations of the earth’s surface, acting for a long time on structures, in this case, the structure of the coke-chemical, metallurgical and cement plants, has not yet been studied enough. It is especially difficult to identify their influence in cases when the structures were reconstructed during the period of additional work..
The longitudinal axes of coke oven batteries No. 1-4 with a coal tower and the main building of a coal washer No. 1 with a disintegrator compartment are located at an angle of 45 ° to the direction of action of deformations of the earth’s surface. The deviation of the longitudinal axes of other objects from the direction of action of the deformations of the earth’s surface is no more than 15 °.
During the period of additional work at the plant, an uneven subsidence of the coke pusher tracks near batteries No. 2 and 4 up to 40 mm was observed. The related malfunctions in the operation of the coke pusher were eliminated by routine repairs. In general, there were no significant complications in the work of the plant, the plant worked smoothly. The cost of repair and restoration work amounted to about 600 thousand rubles.
Metallurgical plant. The territory of the plant covers an area of more than 300 hectares and is adjacent to the by-product coke plant from the side of the seams fall.
