Assessment of Blasting-Induced Ground Vibration …
In an open-pit mine slope, rock mass has multiple joint structures and blasting operations have an obvious influence on its stability. Therefore, accurately predicting the blasting vibration is necessary to ensure slope stability. In this study, the blasting vibration signals monitored at a blasting site with different rock masses were used to investigate the attenuation characteristics of ...
A Comparative Study of Ground and Underground …
Ground vibrations originating from bench blasting may cause damage to slopes, structures, and underground workings in close proximity to an operating open-pit mine. It is important to monitor and predict ground vibration levels induced by blasting and to take measures to reduce their hazardous effects. The aims of this stone are to determine the weaker protection objects by comparatively ...
Whole Body Vibration in Open Pit Mining - A short review
In open pit mining, production is based on the extraction and processing of rocks. It includes fundamental opera-tions such as drilling, charging and blasting, loading, transport and crushing (Matos & Ramos 2010). The-se operations are carried out with equipment that generates vibrations …
Vibration Safety Criteria for Surficial Rock Mass of …
In open-pit to underground mines, partial collapse of surficial rock mass always occurs because the open-pit slopes are subjected to underground blasting mining operations [1 B.-H. Choi, C.-H. Ryu, D. Deb, Y.-B. Jung, and J.-H. Jeong, "Case study of establishing a safe blasting criterion for the pit slopes of an open-pit coal mine", Int. J. Rock Mech. Min. Sci., no. 57, pp. 1-10, 2013.

Vibration response of the waste rock dump in open pit mine ...
In the open pit mine near Jarnoltowek (Poland), phyllite is excavated, and rock waste is deposited on the dump directly in the mine; that is at a distance of approximately 150 m from the quarry face. Blasting operations are used as mining technology here so the rock waste dump could be influenced by these vibrations significantly.
Exposure to whole-body vibration in open-cast …
9-2-2016 · Occupational exposure to whole-body vibration (WBV) originating from the operation of vehicles has long been acknowledged to be a significant risk for low back pain for vehicle drivers ().Operators of vehicles used in open-cast mining are exposed to significant WBV for relatively long periods (2–7).Studies have also indicated that the prevalence of self-reported musculoskeletal pain is ...

Noise and Vibration - KCGM
Noise, vibration and airblast are significant environmental aspects to be managed by KCGM. Historically, residential areas have been located near KCGM and the operations preceding it. Just prior to the formation of KCGM, six underground mines on the Golden Mile operated “around the clock”. With the change of mining method from underground to open pit […]
