Various measurements of the block size or degree of jointing (i.e. density of joints, RQD, block volume, joint spacing) are described. It is concluded that the RQD measurements are encumbered with several limitations and that this parameter should be applied with care. These limitations influence the engineering results where RQD is applied in classification systems, numerical modelling and other engineering assessments.

Forecasting potential slope failure in open pit mines is necessary to maintain safety and mine productivity. Laboratory testing of rain induced landslides in Japan 20 years ago led to an inverse-velocity approach for estimating the time of slope failure.

Slope monitoring radar has emerged in the last ten years as a leading edge tool for monitoring movements in open pit mines, thanks to the ability to rapidly measure wall movements with millimetric accuracy over wide areas in any weather conditions. IBIS-M is an innovative interferometric radar able to provide high spatial resolution, long working distances and fast acquisition time. The first IBIS-M unit deployed in Turkey was installed in 2011 at the large lignite open pit Çöllolar Mine operated by Park Teknik. The geotechnical staff has now 24/7 real time monitoring of the slope stability with a wide coverage on the pit walls with the capability to detect the onset of wall movements far before the occurrence of failure, thus increasing the safety standards and productivity of the mine. The IBIS-M monitoring experience at Çöllolar mine is presented in this paper. <...>

Важность понимания трехмерного кинематического управления при анализе мониторинга смещений в глубоких карьерах над подземными горными работами

Surface mining operations are increasingly involving the design and development of  deeper and larger open pits, often with plans to transition into underground mass mining operations. Experiences at the Palabora Mine in South Africa demonstrate the complex interactions between underground workings and the steep slopes above that may lead to slope movements that potentially pose safety and economic concerns. To properly assess the rock mass response to these interactions for planning of future developments, understanding the controlling influence of geological and geomechanical structures is crucial. Preliminary results are presented from a detailed review of historical slope monitoring data from the Palabora Mine, before and after the initiation of block caving 400-m beneath a 800-m deep pit. This paper demonstrates that a detailed analysis of geology and monitoring data can be used to better understand the kinematic controls of complex rock slope displacements and interactions between open pits and underground mines. This investigative treatment of the monitoring data is important in understanding the failure mechanisms prior to undertaking sophisticated 3-D numerical models
