Ground vibrations arising from excavation with blasting is one of the environmental problems in mining industry. The prediction of ground vibrations and the realization of controlled blasting based on this prediction have a great importance in order to minimize the environmental effects of blasting. The purpose of this study is to analyze the ground vibrations induced by blasting at Akyol Quarry which selected as a test site after the determination of the geomechanical properties of the rock mass with a computer s...

The environmental problems arising from ground vibration has been faced and discussed frequently in various industries such as quarry, mining, civil works, shaft, tunneling, pipe line and dam construction etc. where the blasting operations are unavoidable. In bench blast design, not only the technical and economical aspects, such as block size, uniformity and cost, but also the elimination of environmental problems resulting from ground vibration and air blast should be taken into consideration. One of the fundame...

It is estimated that useful life of world’s well known petroleum reserves will last 40 years, natural gas will last 61 years and coal reserves will be exhausted in 227 years. Decrease in fossile fuel reserves due to fast consuming and environmental damages due to increasing environmental pollution makes it necessary to orient towards new and renewable energy resources. Natural thorium comprising blend of completely radioactive isotopes was first discovered by Berzelius in 1828 and its radioactivity was revealed ...

This paper presents the analysis of ground vibration parameters induced by blasting excavations realized at different sites located close to the residential areas. Within the scope of this study, in order to predict peak particle velocity and determine the slope of the attenuation curve for all sites and rock units, ground vibration components were measured for all blast events over a long period. During the study, while the parameters of scaled distance were recorded carefully, the ground vibration components wer...

This paper presents the results of ground vibration measurements and environmental issues occurred on tunnel blasting activities during KavacД±k-Beykoz waste water tunnel construction under a residential area in Istanbul, Turkey. Within the scope of the study, the blasting pattern of tunnel was engineered by using Tunnel 2000 design software. 5 events in 5 shots at S2 shaft tunnels, , 6 events in 6 shots at S4 shaft tunnels, , 32 events in 32 shots at S6-shaft tunnels and, 7 events in 7 shots at S7 shaft tunnels w...

In this study, the vibration and air shock measurement results are given in order to evaluate the environmental results of excavation works with explosions executed in the agrega quarry by Д°lkdal Mining Industry Ltd. Corp. which is working in the borders of Kemerburgaz region of Ey\"up county in Д°stanbul city on producing agrega. The blasting pattern, explosive material charge parameters and vibration measurement results of each blastings are recorded. In the research, the frequency and particle velocity quantit...

Within the scope of this study, Kuz-Ram and JKMRC fragmentation estimation models were applied to bench blasting operations and pros and cons of models were determined by comparing estimation results with the real fragmentation results obtained from digital image processing technique. On the other side, bench blast optimization method by means of models and digital image processing technique, is introduced in order to get desired fragmentation result from bench blast.

Gold mining is attracting increasing attention in many countries of the world, although it has a major impact on the environment. Large quantities of hazardous chemicals such as mercury or sodium cyanide are consumed to recover gold from its ores. Therefore, this activity should be carefully regulated by means of global directives based on an up-to-date knowledge of ecotoxicity principles and modern environmental standards. In light of recent developments in world gold mining, Turkiye has caught the attention of f...

This paper presents the results of ground vibration analysis induced by blasting during the construction of the Istanbul Kadık\"oy-Kartal metro tunnel. Different rock formations in this tunnel route which is 21,6 km in length were encountered during the excavation with blasting. As a first stage, Test site is divided into 3 main regions with respect to lithology changes in the rock units and Hoek’s Geological Strength Index value of these rock units. In the first region representing S8 shaft tunnels, 59 events ...

The principal disturbances created by blasting in open pit mines can be listed as ground vibrations, air blast and fly rock. All of them can, under some circumstances, cause damage to structures nearby, and can become the source of permanent conflict with the inhabitants living close to the operation site. Therefore, the prediction of ground vibration components is of great importance for the minimization of the environmental complaints. This paper presents the result of ground vibration measurements induced by be...

In the condition that drilling and blasting technique is inevitable depending on the rock mass and material characteristics on mining activities, the fragmentation rate and particle size distribution of the muckpile after blasting has important influences on the performance of subsequent mining activities such as loading, hauling, crushing, grinding etc. and the total costs of that mine. Drilling and blasting is an important step in this process chain and it’s results such as fragmentation, muckpile shape and lo...

This paper presents investigation of the environmental effects of ground vibration and air blast induced by blasting in various quarries located at Turkish Republic of Northern Cyprus. Within the scope of this study, scaled distance components have been recorded for two shots at the BeЕџparmak Company, two shots at the G\"urdaДџ Company, one shot at the Levent Mosaic Company and one shot at the ArpalД±klД± Company, totally 6 shots at different times. And also, ground vibrations and air blasts produced by these sho...

Every action of human being causes changes in environment. Industrial activities realizing large volume of production affect the environment more. Scientific researches not only produce novelty but also try to find solutions in order to reduce the negative effects of these industrial activities. The countries that are good at utilizing their mineral sources have completed their social development in a short time and taken a place among the developed countries. The mining operations have been causing some changes o...

This paper presents the estimation of ground vibration parameters induced by blasting excavations realized at eight different sites located close to the residential areas. Within the scope of this study, in order to predict peak particle velocity and determine the slope of the attenuation curve for eight sites, ground vibration components were measured for all blast events over a long period. During the study, while the parameters of scaled distance were recorded carefully, the ground vibration components were mea...

One of the main subjects of the contemporary project or production/operations management is to make decision. In order to be successful, managers should use modern planning methods. Application of an accepted investment project is as important as its design. As the sources are limited eventually the accepted project which is designed with spending great sources and effort should be completed on time, it is necessary to use them efficiently and cleverly. One of the distinguishing features of contemporary project ma...

The environmental problems arisen from ground vibration and air blast have been faced and discussed frequently in various industries such as mining, construction, quarry etc. where blasting operations are unavoidable. So the ground vibration effects induced by blasting on structures and human beings need to be predicted, monitored, and controlled.
