Blasting is a widely used technique for rock fragmentation in opencast mines and tunneling projects. Ground vibration is one of the most environmental effects produced by blasting operation. Therefore, the proper prediction of blast-induced ground vibrations is essential to identify safety area of blasting. This paper presents a …
for estimating ground vibration produced by blasting oper-ations conducted in a granite quarry, Malaysia. To achieve this aim, a total number of 102 blasting operations were investigated and relevant blasting parameters were mea-sured. Furthermore, the most influential parameters on ground vibration, i.e., burden-to-spacing ratio, hole depth,

The dimensions of the hypothetical models were considered 2 m in the x direction (cutting depth of the quarry face), 20 m in the y direction (quarry face length), and 4.5 m in the z direction ...
Blasting parameters comprising maximum charge per delay and powder factor were prepared to predict flyrock using empirical and intelligent methods. An …
Drilling and blasting is an economical and well-known technique for rock fragmentation in the civil works as well as surface mines. Only 20–30% of the explosive energy is applied for the desired rock fragmentation and the rest of energy released by blasting dissipates through the ground leads to some unwanted effects, such as fume …
The input parameters into the models are the distance from the point of blasting to the point of measurement (D), the weight of charge per delay (W), rock density (q), and the Schmidt rebound ...
Based on this figure, blast No. 29 has the maximum level of risk (maximum VI), equal to 42.02. Whereas, blast No. 45 has the minimum level of risk (minimum VI), equal to 24.82. Moreover, the overall risk of flyrock was obtained as 32.95 which according to Table 3, is considered as low to medium degree of vulnerability.
the PPV of 2.535 mm/s and 3.568 mm/s was the lowest and. highest value. Apart from that, Quarry B scored the lowest. value of 0.220 mm/s and highest value of 3.060 mm/s. This. shows us that the ...

Blasting, as the most frequently used method for hard rock fragmentation, is a hazardous aspect in mining industries. These operations produce several undesirable environmental impacts such as ground vibration, air-overpressure (AOp), and flyrock in the nearby environments. These environmental impacts may cause injury to human and …
