DEVELOPMENT OF A METHODOLOGY FOR STABILITY MONITORING OF A DEFENSE EMBANKMENT LOADED WITH FREQUENT TRAFFIC: THE EXAMPLE OF THE KOVIN MINE

Abstract

In the present paper, the authors develop a methodology for stability monitoring of the hydrotechnicaldefensive embankment that is exposed to heavy frequent traffic. The proposed methodology envisages several phases of observation, work and monitoring: (1) macroscopic observations, (2) geophysicalgeoelectric tests, (3) group of exploration works, (4) model formation, (5) establishment of a monitoring system, (6) acquisition data processing and modeling. Four of the six proposed phases are illustrated by the example of the left-bank Danube embankment used by the Kovin coal mine for the needs of coal
truck haulage.

The results of the performed research indicate that there are no deformations that endanger the defensive function of the embankment. In order to ensure safe coal truck haulage and preserve the function of the embankment, it is proposed to establish a system for geophysical, hydrogeological and geotechnical monitoring, to form a model for simulating the behavior of the embankment for different hydrometeorological conditions (consequently, for different consistency states and material
compaction), and for different load conditions.
