Auscultation of the RTH flotation tailing dump in Bor with reference to the stability of dams and dykes at the tailing dump

Abstract

The RTH flotation tailing dump, located in the old open pit RTH in Bor about 500 m southeast of the Flotation Plant, has been in continuous operational work since 1985. The flotations tailing dumps are important mining facilities that are constantly changed during their exploitation period. Due to the changes occurring in the tailing dump during its exploitation, it is necessary to perform a continuous technical and technological surveillance-auscultation in order to collect parameters in real time to predict the phenomena, which will enable the normal exploitation of tailing dump. This paper presents the current state of the flotation tailing dump RTH, based on the auscultation monitoring program, carried out in the period August 2020 to February 2021. As for the normal exploitation of the flotation tailings dump in safe and stable conditions, a special attention is paid in this paper to the stability analysis of the dams I and II, as well as the sand dyke between them.
