The Bureau of Mines studied blastproduced ground vibration from surface mining to assess its damage and annoyance potential, and to determine safe levels and appropriate measurement techniques. Direct measurements were made of groundvibrationproduced structure responses and damage in 76 homes for 219 production blasts.

The material involved in the transmission of surface waves is a zone about one wave length in thickness. All surface waves are generated at approximately the same time and, in the immediate vicinity of the blast, the total surface, displacement is controlled by the total energy contained within the waves.

AbstractUncertainties in vibration analysis from blasts can be attributed to the problem of determining the actual amount of explosive detonating within a specific time interval, and the number of holes effectively contributing to the resulting particle velocity. This paper describes the results of a systematic study carried out to investigate these effects at iron ore mines in India.
