The amplitude of vibration due to blast wave was observed to be reduced with increase in the height of the building and hence drop in the level of nuisance in the upper floors. The investigation in some of the mines revealed that in case of machine cut, the blasting in the lower section generated more vibration than that of the upper portion.

Vibration Vibration of a building is mostly man made. Where movement of building exists, this can cause distress to the structure and finishing. ... Uniform settlement may not seriously affect the building but mining subsidence may induce differential movements and may cause problems associated.
The most common source of vibration that can cause nuisance in building applications is human activity, usually walking. Although small in magnitude, walkinginduced vibrations can cause a nuisance to people working or living in the building, especially to the use of sensitive equipment or to those engaged in motionsensitive
Jan 03, 2017018332Exposure to wholebody vibration WBV negatively impacts the health and safety of exposed mine workers. Offroad mining equipment operates on rough surfaces under harsh operating conditions that produce WBV and mechanical shock. Vibration is often complex, contains many frequencies, occurs in several directions, and changes over time.
Circular vibrating screen is widely used in the materials classification of mining, building materials, transportation, energy, chemical industry and other industries because of its long flowing line and many screening specifications.
Vibration is typically used in soil compaction equipment because it improves the efficiency of the equipment by directing energy into the substrate which overcomes the friction between soil particles, causing the soil particles to realign and fill in the void spaces, thus resulting in greater soil density and preventing excessive building settlement.
