· The blasting requires the use of seismic monitors when the amount of the explosives exceeds specified amounts, which vary by the distance to the nearest residence. The law establishes maximum ground vibration levels, although these limits do not apply if the affected structures are owned and occupied by the permittee, or are leased by him and the lessee signs a waiver.
· Quarrying operations plan. You may need to provide an operations plan along with your application to extract riverine quarry material. The Department of Resources will determine if a plan is required and what information needs to be provided. Contact your local business centre before lodging your application for advice.
· The accepted method of prediction is to plot measured peak particle velocity values against a scaled distance value for each measurement. The scaled distance value is taken as the blast/receiver separation distance divided by the square root of the maximum instantaneous charge weight of explosive in the shot from which the measurement was taken.
