Title:

METHOD AND APPARATUS FOR WIRELESS BLASTING

Document Type and Number:

WIPO Patent Application WO/2015/084707

Kind Code:

A3

Abstract:

Systems, methods, blasting machines and wireless bridge units are presented for wireless blasting for safe firing of detonators under control of a remote wireless master controller in which the blasting machine is connected by cabling to the wireless bridge unit and power to a firing circuit of the blasting machine is remotely controlled via the bridge unit. The bridge unit selectively provides first and second firing messages to the blasting machine contingent upon acknowledgment of safe receipt of the first firing message by the blasting machine, and the blasting machine fires the connected detonators only if the first and second firing messages are correctly received from the bridge unit. A wireless slave blasting machine is disclosed, including a wireless transceiver for communicating with a remote wireless master controller, which fires the connected detonators only if first and second firing messages are wirelessly received from the master controller.
