Abstract
Disclosed herein are methods for communicating wireless signals between components of a blasting apparatus, with the intention of conducting a blasting event. In preferred embodiments, the methods are particularly suited to through -rock transmission of wireless command signals, and optionally wireless calibration or synchronization signals, thereby to achieve timed actuation of explosive charges positioned below ground under the control of one or more blasting machines located at or above a surface of the ground, with a high degree of accuracy. Further disclosed are blasting apparatuses and components thereof suitable for use, for example, in conducting the methods of the invention.
