摘要： A device and a method thereof for determining detonator information by using a wireless signal are proposed. The device includes an electromagnetic wave reception unit configured to receive an electromagnetic wave transmitted from a detonator in a blast hole, a coordinate derivation unit configured to detect the received electromagnetic wave and derive the electromagnetic wave as coordinates, a blast hole location determination unit configured to determine a location of the blast hole on the basis of a flickering pattern of the electromagnetic wave derived as the coordinates, and a detonator ID acquisition unit configured to acquire an ID of the detonator in the corresponding blast hole on the basis of the determined location of the blast hole.

摘要： Ethernet systems, methods and blasting machines are presented for remote turn on of the blasting machine and reliable fire and arm commands issuance. 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 or Ethernet primary controller 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.

摘要： The present invention is directed toward an addressable ignition stage which produces an output sufficient to detonate a secondary explosive, generally. The present invention comprises addressability and ignition functions that may be used together or separately to incorporate a high-power resistor with a thermally conductive substrate allowing for operation at high temperatures for ignition. The ignition stage is amendable to high volume production, exhibits a high degree of reliability, robustness and operational dependability for use alone or configurable into existing technology.

摘要： An apparatus and method for designing a blasting sequence for a drilling pattern of a round. The apparatus (11) is configured to assist selecting one or more drill holes (3) for each time delay of the blast. The apparatus calculates burst volume (VB) for the selected drill hole set (34) and ensures that previously blasted free volume (VF) can receive it when being fired. The apparatus may also take into account burst angles burst distances and ground vibrations when suggesting the drill hole sets.
