PROVIDING SAFETY FOR MINE SURFACE OBJECTS BY UPGRADING OF THE RELIABILITY LEVEL
Journal Title: Computer Science Information Technology Automation - Year 2017, Vol 1, Issue 6
Abstract
The method for analyzing defect distribution as one of the methods for assessing the technical condition of structural elements of the mine surface constructions is developed. The defect distribution method determines future works on reliable operation and provides a high-leveled safety for the mine surface objects in terms of a stressed state of the structural elements at the design stage. The analytical model for determining physical wear of facility at survey was developed and its actual survivability was established. An object is considered as a system of hierarchically connected groups with the identical bearing elements for determining the standard levels of reliability. The main parameters considered in modeling are as follows: actual state and survivability of structural elements at their survey. The obtained model determines the state of the operated facility in the dependencies of the building bearing structures on its survivability. The threshold values of survivability are determined, at which the surface object of the mines passes into a qualitatively different state - from normal to satisfactory, from satisfactory to unsuitable, and from unsuitable to emergency. The proposed methodology for assessing the safety of operated surface structures can be used in practice to assess the degree of survivability, the technical condition and safe residual resource. The scientific novelty of the method proposed in the work is an adequate description of the technical state of the structural elements of the mine surfaces, which takes its place among the new modern experimental studies of materials and structures of the surface objects. The method for analyzing defect distribution enables to determine the safety and reliable operation for the surface objects of mines. The proposed measures improve the reliability of the operated facility, as well as preserve the lives for the enterprise’s employees and tangible assets.
