Abstract
Open mining operations generate deep open pits, and the industrial infrastructure and buildings become closely spaced with the open mining zone as a result. The situation requires implementation of integrated monitoring and periodic assessment of pitwall stability considering up-to-date data on properties and condition of rock mass. This article describes an approach to monitoring and assessment of pitwall stability on a hazardous site. The periodic seismic profiling reveals great disruption of the test site. The stability assessment of the test site using the limit equilibrium method shows the slope instability. It is concluded that prediction of failure zones on the test site is advisable to carry out by integrating the field inspection and computational methods of slope stability control.
