Mar 14, 2012· Environmental Consequences of Open Pit Mining An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones ...
In this work, the recorded measurements of ground vibration in Metlaoui open pit mine of phosphate were analyzed according to several established criteria of damage in order to study the ground vibrations characteristics resulting from production blasts and to evaluate the vibrations impact on the nearby structures. Study area
The Rampura Agucha open-pit lead zinc mine is producing 5.7 Mt/a of ore and has started its underground part, which is slated to produce initially 2–2.4 Mt/a and 4.5 Mt/a in the near future. The open-pit mine is currently working at 326 m depth and is designed to reach 421 m deep.
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 paper are to determine the weaker protection objects by comparatively ...
This thesis investigates the response of high-walls under the effects of vibrations from mine blasting. In this research, the relationship between the high-wall response, the geometry of the slope, the frequency and the amplitude, of the ground vibration produced by blasting, is .
Mar 14, 2012· An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones, that are relatively close to the surface.
Sep 05, 2017· Goldcorp's Porcupine Gold Mines has eleven permanent vibration monitors surrounding the Hollinger Open Pit. The Timmins community has spoken, so we're giving you (even more) facts about blast ...
Location: Labrador, Newfoundland, Canada Owner/Operator: Iron Ore Company of Canada Wabush 3 Open Pit Mine Project in Labrador will provide iron ore to Iron Ore Company of Canada's (IOC) existing concentrator plant and will also provide a new source of iron .
1000 kg of explosives fired in the overburden of a Hunter Valley coal mine. The P wave arrives first followed by the various reflected and refracted vibrations associated with the P wave. This vibration gradually reduces until approximately 800 ms later, when the S wave arrives with its associated reflected and refracted waves.
The ground vibration and airblast limits in the Guidelines have been set to minimise ... Guidelines for the assessment of geotechnical risks in open pit mines and quarries ... In cases where the separation distance is reduced as new sensitive sites are developed closer to an existing mine or quarry, the existing vibration and airblast criteria ...
When blasting rock, both vibrations in the ground and in air is generated. We can measure the pressure at the shockwave as well as vibrations in the ground and on buildings close to the site. This is most often performed near open pit minings or when blasting rock during preparations for construction.

surface coal mine, because greater volumes of material must be moved requiring larger blast designs than the trench. Often blasts are hundreds of feet away, and the ground movement begins to slow its rate of travel due to the distance. Even when farther away the ground vibration will reach your property before the air overpressure, consequently
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Teck's Red Dog surface zinc mine adds US$6.5 million annually through blast monitoring. Centerra Gold's Mount Milligan open cast copper mine recovered over US$600,000 of ore in one blast. Anaconda Mining's Pine Cove gold mine reduced dilution from 20% to less than 5% and generated a 15% increase in recovered tonnes, valued at US$15-30k ...

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 ...
