ABSTRACT
The experimental version of the multichannel measuring equipment package Karier-M has been designed and manufactured at the Institute of Mining, Siberian Branch, Russian Academy of Sciences, for slope stability monitoring in deep open pit mines. The equipment package can operate in rigorous climate conditions of Siberia and Russia’s Far North and is now deployed in Russia’s deepest open pit diamond mine in the Republic of Sakha.
The dynamic impact of blasting on pit slopes involves displacement and rotation of geo-blocks in the pitwalls; the values and directions of the displacement and rotation are governed by the positional relationship of the geo-blocks. Prior to taking after-the-blast position, the geo-blocks under control carry out vibrational motions (loosen).
Phenomenon of translational motion of adjacent geo-blocks, i.e., transmission of motion between them, has been observed.

Keywords: measuring equipment package, rock mass, pit slope, geomechanical conditions, open pit mine.
