MONITORING OF THE BENCHES AND SIDES STABILITY OF THE QUARRIES

English abstract

The increase in the volume of opencast mining is facing the main problem of ensuring the stability of the open pit slopes on the planned contour. To achieve this goal, required reliable geomechanical support of the parameters of the slopes of quarry benches and sides, then placing them on the planned contour using special technological schemes of the slopes and constant instrumental monitoring of their condition in an automated mode. The main emphasis in the work has been given to the method of instrumental monitoring of the quarry’s arrays state using modern instruments with the analysis of their measurement’s accuracy. The approved instrumental methods of monitoring at the open-pit mines of Kazakhstan are presented.
