A parametric study of ground vibration induced by quarry …
Blasting is a common technique for rock breakage in the numerous civil and mining engineering activities such as excavation, leveling, and tunneling. However, this technique has several environmental issues, such as ground vibration. More importantly, the peak particle velocity (PPV), as the main indicator of ground vibration, should be …

Mining and Quarrying
Mining and quarrying. Mining is the process of extracting buried material below the earth surface. Quarrying refers to extracting materials directly from the surface. In mining and quarrying, water is used and gets polluted in a range of activities, including mineral processing, dust suppression, and slurry transport.

Statistical modelling of the blast design parameters
Mining and construction sites experience ecological consequences, such as ground vibrations and fly rock, owing to blasting activities. Apart from the traditional techniques, it is critical to determine the design parameters of a blast which influence the ground vibrations, created by the blasting activities, and to mitigate the effects of ground …
