Blasting complaints are consuming an increasing amount of time and resources. This worsening situation has spawned new methods for relaying the public’s concerns. The direct measurement of crack response to both long term environmental and blast vibration effects with the same sensor exemplifies one new approach, which can be helpful in the process of educating quarry neighbors about the large ...

Rock fragmentation in mining and construction industries is widely achieved using drilling blasting technique. The technique remains the most effective efficient means of breaking down rock mass into smaller pieces. However, apart from its intended purpose breakage, throw, heave, operations generate adverse impacts, such as ground vibration, airblast, flyrock, fumes, noise, that have significan...

Centrifugal booster fans are important equipment used to recover blast furnace gas (BFG) for generating electricity, but blade crack faults (BCFs) in centrifugal booster fans can lead to unscheduled breakdowns and potentially serious accidents, so in this work quantitative fault identification and an abnormal alarm strategy based on acquired historical sensor-dependent vibration data is propose...

In recent decades, the effects of blast loads on existing structures have gained considerable attention due to increase in threat from various activities. Site-specific empirical relationships for calculation blast-induced vibration parameters like Peak Particle Velocity (PPV), Acceleration (PPA), and Displacement (PPD) are commonly used estimation impact blasting an adjacent tunnel. However, th...
