Numerical Analysis of the Primer Location Effect on Ground Vibration Caused by Blasting
Ground vibration is one of the undesirable results of blasting operations. Different methods have been proposed to predict and control ground vibration that is caused by blasting. These methods can be classified as laboratory studies, fieldwork and numerical modeling. Among these methods, numerical modeling is the one which saves time and cuts costs since it takes into account the basic princip...
متن کاملPredictions of Experimentally Observed Stochastic Ground Vibrations Induced by Blasting
In the present paper, we investigate the blast induced ground motion recorded at the limestone quarry "Suva Vrela" near Kosjerić, which is located in the western part of Serbia. We examine the recorded signals by means of surrogate data methods and a determinism test, in order to determine whether the recorded ground velocity is stochastic or deterministic in nature. Longitudinal, transversal a...
متن کاملAn Assessment of Blasting Vibrations: A Case Study on Quarry Operation
Problem statement: One of the major environmental concerns related to blasting operation in mining and civil engineering projects is ground vibration. Approach: This study presented an assessment of ground vibrations caused by the blasting experiments at a marlstone quarry in northern Italy. The primary goal of this study was to determine the vibration level in order to protect dwelling area ad...
متن کاملVibrations caused by train traffic and the effect of its mitigation on the quality of living
Railway traffic induced vibrations in dwellings often cause irritation or disturb the inhabitants. Mitigation has been performed, and measurements prove their effectiveness. The effect of vibration countermeasures on the quality of living however has not been studied earlier. The objective of the study was to evaluate the effects of vibration mitigation compared to the increase of inhabitant sa...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
