Improved Signature Hole Analysis for Blast Vibration Control in Open Pit Mines ... and in metal mines to control vibration levels to minimize the impact of blasting on the performance of large open pit slopes. Introduction. In the mining production cycle, blasting is the most economical and efficient method to fracture and move the ground (rock ...
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.
Vibration Safety Criteria for Surficial Rock Mass of Open . Combined with the field blasting operations during the openpit to underground mining in Daye iron mine, the blasting vibration .
Blast vibration effects in an underground mine caused by open-pit mining Article (PDF Available) in International Journal of Rock Mechanics and Mining Sciences 80:79-88 · September 2015 with ...
Markéta Lednická and Zden ěk Kaláb : Vibration response of waste rock dump in open pit mine caused by blasting operation 72 Only the mined out part of the quarry was at the disposal of waste rock deposit. The dump had four levels at the time of performed seismological measurement (Fig. 1, 2), the height of the dump was about 23 m, and
Combined with the field blasting operations during the open-pit to underground mining in Daye iron mine, the blasting vibration safety criteria is calculated. It is obtained that the blasting vibration safety criteria for the north slope and the south slope are 11.08cm/s and 10.20cm/s respectively.
ASSESSING AND MONITORING OPEN PIT MINE HIGHWALLS Jami M. Girard1, P.E., C.M.S.P. 1Mining Engineer, National Institute for Occupational Safety & Health, Spokane Research Laboratory, 315 E. Montgomery Ave., Spokane, WA 99207 .
In surface mining, blast damage has a significant im dures into routine mine-production pact on slope stability. (1982) noted that, if backbreak is not controlled, a de crease in the overall pit-slope angle control to maintain blasting quality Abstract will ultimately be necessary, and .
body vibration exposure and impulsive shock impacts, which are very typical in the open pit mining industry and the operation of heavy equipment vehicles, do exist. The typical approach to quantify whole,
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 ...
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.
placement, the overall mining noise produce from the mining equipment varies in quality and level. Hearing loss from noise created by mining industry can impair the quality of life through a reduction in the ability to communicate with each other. Keywords: Noise, dumper, mining, open pit mine, hearing loss, impair, hearing loss
Body waves travel through the mass of the rock, penetrating down into the interior of the rock mass. There are two kinds of body waves: compressional waves and shear waves.The compressional wave is a push-pull type wave that produces alternating compression and dilatation in the direction of wave travel, such as occurs in a stretched spring.
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 maximum blast vibration levels permitted at Waihi's mining operations are specified in the consent conditions. These limits are lower than all other known international standards for blast vibration. Fixed monitoring stations are located at strategic sites. A mobile vibration monitor is .
Surface Mining, U.S. Department of the Interior, located in Denver, Colorado. The module is an example of the technical assistance the Federal government furnishes States to assist them in meeting the requirements of the Surface Mining Control and Reclamation Act of 1977, upon which their State surface coal -mine regulating programs are based.
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 ...
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 ...
The potential air-blast and vibration impacts related with the Chimiwungo open pit of Lumwana mine are typical for a large open -pit mining operation and generally include: Operation of lightand heavy vehicles for transportation of personnel, materials and equipment within the site.
