·Kahriman 2004 analyzed vibration components for 73 blast events at a limestone quarry located in Istanbul Turkey An empirical relation between PPV and scaled distance was developed by Kahriman et al 2006 based on measurement of vibration caused by bench blasting in an open pit mine in Turkey
The ground vibration components were measured for 73 blast events during the bench blast optimization studies during a long period In The aim of this study is to predict peak particle velocity level at a limestone quarry located in Istanbul Turkey The ground vibration components were measured for 73 blast events during the bench blast
·The main objective of this study is to evaluate the influence of blast induced acceleration on the stability of slopes at Arakli Tasonu limestone quarry where a planar shear failure has recently been observed The planar failure occurred within rock layers consisting of limestone and clayey limestone The triggering mechanism of the planar shear failure was
In the second × m square blast design pattern the values of F80 increased to 79 cm an acceptable level for the crushing machines installed in NCQ limestone quarry On the other hand this design led to the creation of a large numbers of blocks formed over size boulders which posed difficulties for charging and transporting the rock
·Limestone Quarry Keywords Blast Design Environment Limestone Quarry Local Geology limestone quarry area and some of them even located very close or next to quarry s boundaries Of late the
3 ·"K" ranges from "K" taken is for limestone "η " is ratio of length of least resistance line of first row of blast holes to face height usually equal to " ἣ "is ratio of distance between rows of blast holes to length of line of least resistance usually equal to
·The Mugher limestone deposit and other raw material resource areas are located 110 km to the NNW of Addis Ababa in the Federal Democratic Republic of Ethiopia The limestone deposit has been named after the village Mugher where it is located The location of the Mugher limestone deposit is shown in with the coordinates
·Drilling of explosion blast holes in Pir Ali limestone quarry of Abyek Cement Plant is carried out using five drilling machines including two semi hydraulic two pneumatic and one Russell drilling machines The benches in this mine generally have a height of 8 m and blast holes with a diameter of 76 mm and length of 9 m are bore to blast
·quarry Rawan limestone quarry Sonadih limestone quarry and Paraswani limestone quarry were selected for conduction of the trial blasts The main consider ation behind the selection of limestone quarries was the apparent similarity in geotechnical properties of the rock mass in each of them and analogous blast practice The limestone deposits
·This study examined the selection of powder factor in blast holes at Dangote limestone quarry located in Obajana Kogi State North Central Nigeria After preliminary field studies ten 10 blasts with varying designs and powder factors were studied and three 3 rock samples carefully collected from the limestone quarry for laboratory
