A communication module which is linked to a detonator which is initiated in response to a fire command signal, and wherein the communication module includes a transmitter which transmits a wireless signal which is dependent upon initiation of the detonator and which contains or conveys an identifier which uniquely identifies the detonator.

Blast confirmation

In a blasting system a method of determining which borehole in a plurality of boreholes at a blast site is closest to a tagger, wherein latitude and longitude coordinate values for each borehole are determined and by using subsets of the longitude coordinates and latitude coordinates, and by performing a haversine calculation the position of the borehole which is closest to the tagger is determined.

Detonator position determination

A blasting system which includes a number of roving GPS receivers, and associated taggers, which communicate with one another and with a control mechanism, and a reference GPS receiver which transmits RTCM corrective positional data which is stored at each roving GPS receiver to improve the accuracy of coordinate determinations for boreholes.
