Research on risk assessment technology for transmission lines in mining affected areas

Abstract

This article studies the correlation between ground surface deformation of transmission lines in mining affected areas and various geological and human factors, and it constructs the corresponding numerical models. By analyzing the distribution of goaf areas, geological structures, slope structures, and other factors that affect transmission lines, the tower foundations’ deformation characteristics and disaster mechanisms under mining conditions have been clarified. On this basis, research on ground surface deformation risk prediction technology was carried out using monitoring data, and a safety operation risk assessment model was established to achieve rapid identification and accurate prediction and warning of hidden dangers. At the same time, a monitoring, early warning, and risk assessment system has been constructed and demonstrated to be highly accurate and practical in pilot verification. In addition, through the comprehensive application of physical models and numerical simulations, the influence of different ground surface settlements on the deformation of transmission line towers was explored, providing important references for improving the safety of transmission lines.
