Analysis of ground vibrations caused by bench blasting at Can Open-pit Lignite Mine in Turkey

Abstract

The principal disturbances created by blasting in open-pit mines are vibrations, air blast and fly rock. All of these problems, under some circumstances, may cause severe damage to structures nearby and, apart from that, these can be the possible sources of permanent conflict with the inhabitants who live close to the operation. Therefore, a vibrationcontrol study was performed in mines on the basis that prediction of ground vibration components is of great importance in minimising environmental complaints. This paper presents the results of groundvibration measurements induced by bench blasting at Can Open-pit Lignite Mine, which is located close to the residential area of Can town. Within the scope of this study, in order to predict peak particle velocity and determine the slope of the attenuation curve for this site, ground-vibration components were measured for blast events. During the study, the parameters of scaled distance were recorded carefully, and the ground-vibration components were measured by suitable monitors for 54 blast events. At the end of the evaluation of data pairs, an empirical relationship, which gives the average line at a 95% confidence level and an upper bound 95% prediction line with a good correlation coefficient, was established and suggested for this site.

Prediction of ground vibration due to quarry blasting based on gene expression programming: a new model for peak particle velocity prediction

“…According to many researchers (Bureau of Indian Standard 1973;Kahriman 2002;Singh 2004;Singh and Singh 2005;Sawmliana et al 2007), PPV is set as an index for measuring ground vibrations as it is an important indicator for controlling the structural damage criteria. During a few past decades, in order to predict PPV produced by blasting, many vibration predictors have been proposed empirically (e.g., Duvall and Petkof 1959;Langefors and Kihlstrom 1963;Davies et al 1964;Ambraseys and Hendron 1968;Roy 1993).…”

Classification and regression tree technique in estimating peak particle velocity caused by blasting

“…Many researchers [6,[11][12][13][14] have observed that the PPV is used as an index for measuring the ground vibrations as it is an important indicator for controlling the structural damage. During past few decades, many empirical vibration predictor equations have been proposed to calculate the PPV produced by a blast (e.g., [15][16][17][18][19]) using two factors, namely maximum charge per delay and distance from the blast face.…”
