The paper considers the safety of operating hydraulic structures for reclamation. Such research is imperative today due to the high risk of accidents at such structures. Meeting the technical, economic, environmental, and aesthetic requirements to hydraulic structures is absolutely necessary; otherwise, significant damages may ensue. Hydraulic structures (HS) are operated in two ways of organizing the maintenance and repairs: periodic inspections to check the condition of HS elements and find whether repairs are necessary; and carrying out pre-scheduled repairs and adjustments. Analysis of the two methods reveals that scheduled preventive repairs can ensure the fail-safe and reliable operation of hydraulic structures, and are therefore fundamental to proper operation.

The article shows the procedure for determining the values of the stability index of hydraulic structures (earth dams). An approach to the creation of an engineering methodology for carrying out operational calculations for predicting the state of an earth dam under the influence of known characteristics of damaging factors of rapidly developing dangerous natural phenomena and man-made processes is presented. One of the directions of application of the proposed approach is shown — the definition of rational parameters for the protection of hydraulic structures and the development of a plan of measures to achieve them.

This article deals with the negative impact of slag dumps and sludge collectors on the environment. The development of measures to prevent, reduce (limit), compensate and eliminate potential and actual damage caused by sludge collectors of the surrounding natural environment is a highly important issue. It was also revealed that the current legislation of the Russian Federation does not account for the amount of economic damage caused to the recipient objects by environmental pollution and as a separate component of damage to atmospheric air and soils. Therefore, it is suggested to make additional changes to the order of Rostekhnadzor No. 120 “On approval of the methodology for determining the amount of harm that may be caused to life and health of individuals, property of individuals and legal entities as a result of an accident of a hydraulic structure (except for shipping and port hydraulic structures)”.
