Stephen Iverson, Chuck Kerkering, William Hustrulid NIOSHSRL . Abstract . Perimeter control blasting is common in civil construction projects but not as common in mining. A poorly designed and executed underground mine development blast design can result in unwanted wall rock damage. This damage increases the risk of rock falls and injury.

The purpose of this instrument is to allow the blaster to check the connections and condition of the caps, wires, connections and completeness of the circuit. The blasting galvanometer has an indicator needle which measures resistance of the circuit to which it is attached.
