Flyrock is one of the major disturbances induced by blasting which may cause severe damage to nearby structures. This phenomenon has to be precisely predicted and subsequently controlled through the changing in the blast design to minimize potential risk of blasting. The scope of this study is to predict flyrock induced by blasting through a novel approach based on the combination of .
Aug 02 2019 To determine the distance of fly-rock the iGeoTrans appa product of Hanoi University of Mining and Geology Hanoi Vietnamwas utilized as shown in Fig. 7c. This app can determine the positions of blast sites and fly-rock through global positioning system GPS assisted GPS GLONASS Wi-Fi and cellular network for positioning . Finally a database includes 210 observation was
May 21 2010 Flyrock a rock fragment thrown to an excessive distance is a random event and an ongoing problem in opencast bench blasting. Existing criteria for a Flyrock Danger Zone are rigid such that blasting may not be permitted where there are structures within about 100 m. A statistical approach to the problem is proposed and new concepts of Factor of Safety Threat Levels and Flyrock Risk .
Mar 20 2015 Mines quarries and construction sites face environmental impacts such as flyrock due to blasting operations. Flyrock may cause damage to structures and injury to human. Therefore flyrock prediction is required to determine safe blasting zone. In this regard 232 blasting operations were investigated in five granite quarries Malaysia. Blasting parameters comprising maximum charge per
