Control of Vibration and Blast Noise from Surface Coal Mining. Volume IV. Executive Report.

摘要

A series of controlled experiments was conducted at four surface coal mines to study the effects of certain blast parameters upon the ground and air vibration. Preliminary scale-model blasts were conducted at a quarry to provide basic data. This report presents an analysis of the data obtained from the field tests. Where possible,expressions have been developed that will be helpful in establishing guidelines for the design of blasting to minimize adverse results with respect to noise and ground vibration.
