Purpose. Making one of the reliability assessment methods of structural elements of objects surface mines as a system of risk analysis of possible defects in the construction of structures and organizational reasons that can lead to an accident, allowing to manage security in the operation.

Methodology. Developed the analytical model for determining the accident risk assessment of structures (structural collapse), in which made the diagnostics of the technical state of the object surface mines and found the value of the actual degree of survivability. To determine the risk standard levels an object is represented as a system consisting of connected groups of the same type of bearing elements. During the simulation are considered the main parameters: technical, human and organizational factors, as well as the cost of the work related to improving security.

Scientific novelty. The scientific novelty of proposed method is an adequate description of reliability degree of bearing elements of the object surface mines, which will take its place among the new modern experimental studies of the structures of the industrial site.

Practical significance. Made the methods for system risk analyses of possible structural defect, which allows to determine the reliability of an object at a particular time and safe residual life. As a result of the proposed measures increased assessment of costs and benefits from implementation of measures to reduce the risk of an accident based on the hazard identification. Developed the final recommendations for the safe operation facilities using the existing regulatory framework on labor protection.

Results. Identified three areas of risk like negligible risk, acceptable risk (which is not so small to be ignored, but not large enough to consider it excessive) and unacceptable risk (so large that it is considered excessive). Obtained the model that allows to perform systematic risk analyses of possible structural defects in construction, by comparing with its actual acceptable boundaries. The proposed method can be used in practice to assess the survivability degree and safe residual life of the object.

Key words: risk, accident, reliability, safety, residual life.
