Mine geological disaster is a complex non-linear system. The traditional prediction model has the disadvantages of low accuracy and poor reliability. In order to solve this problem, open-pit mine slope displacement taken as research object. Based on new algorithm extreme learning machine (ELM), intelligent sparrow search (SSA) are introduced determine weights thresholds input layer hidden ELM. ...

Persistent Scatterer interferometry (PSI) represents a powerful tool for the detection and monitoring of tiny surface deformations in vast areas, allowing a better understanding of its triggering mechanisms, planning of mitigation measures, as well as to find better solutions for social and environmental issues. However, there is no record hitherto of its use in active open pit mine in tropical...
