High Resolution Seismic Monitoring in Open Pit …
There is a strong indication that mine seismicity in open pit environments is generally caused by non-shear mechanism. This seismic mechanism is poorly understood and needs further investigation as it has important implications with respect to the modelling of rock failure, rock mass behaviour and the design of long-term large rock slopes.

Seismic refraction and seismic tomography proved as valuable method for geological and structural reconstructions of the open pit and rockslide that are necessary preconditions for the rockslide movement prediction and suggestions of the effective landslide control.
Seismic Monitoring at the Fimiston Open Pit …
The Kalgoorlie Consolidated Gold Mines (KCGM) Fimiston Open Pit is mining through a dense network of disused level workings and open stopes of greatly varying sizes. The condition of the stope crowns and remnants is often unknown, and ultimately these structures become a significant proportion of the production floor and pit walls. Significant seismic events...

Seismic section along profile №1 on Naugarzan landslide In 2017, seismic field works with a 24-channel seismic station LAKKOLIT-24M were provided on the newly formed Kokand landslide on Angren open pit (figures 3,4). Seismic sections with seismic horizons with different velocities respectively, were organized according to seismic data processing.
Passive Seismic Monitoring of Mine-scale …
Passive seismic monitoring was carried out at the mine to investigate whether the geothermal activities could be detected and located using microseismic techniques in a mining environment. In this trial, sixteen triaxial geophones which can withstand temperature up to 200°C were used and installed in four deep boreholes inside the pit.
Determination of Seismic Safety Zones during the Surface ...
The “Buvač” open pit has been operating since 2009, and to model the drilling and blasting works in time and space monitoring of these works was carried out from the aspect of defining the safety seismic distances or allowed explosive quantities in relation to the endangered objects on the mine and its immediate surroundings.
