A system and apparatus for plasma blasting comprises a borehole, with a novel blast probe, the probe comprising a high voltage electrode and a ground casing tube with a ground and/or electrode deflector. The ground and/or electrode deflector focuses a plasma blast through openings in the probe, directing the blast force away from the ends of the probe, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The blasting media comprises water alone or in combination with other materials. The robust blast probe permits the aiming of the blast outside of the probe.

A wireless detonator system wherein a blast control unit communicates bidirectionally with at least one tagger and with detonators, prior to deployment thereof, using a NFC technique, and a transmitter/receiver assembly communicates with each detonator a tan ultralow frequency.

The application relates to a charging system for charging at least one charging hole. The system comprises a charging boom, sensors of the boom, a movement mechanism of the boom, a charging head of the boom for charging the at least one hole, and a controller for controlling the boom. The sensors obtain location information relating to the boom. The controller defines locations of the charging head in a co-ordinate system of the boom on the grounds of at least the obtained location information. The controller also operates the movement mechanism to move the charging head between the defined locations in accordance with precalculated movements.

A perforation gun assembly comprising a plurality of guns with a box fitting at one end and a modified pin fitting at the distal end; the modified pin fitting further comprising an end cap secured to an internal charger carrier, aligning a plurality of shape charges with scallops in the gun casing; and having a pressure switch, which connects to an electrical connection point at the box end of a charger carrier in an adjacent gun. The end cap being captured between the pin of one gun and the internal edge of the mating gun to protect and channel blast force to the pressure switch.

The present disclosure relates to a blasting system, the blasting system including: a drilling device configured to form blasting holes on a blasting target on the basis of a blasting design map; a charging device configured to place explosives in the blasting holes; detonators configured to detonate the explosives; a central control unit configured to confirm a position of a worker in real time, the worker driving the detonators; and a worker terminal configured to transmit worker position information to the central control unit, the worker position information indicating the worker position. The blasting system of the present disclosure can automatically connect the detonator to the central control unit, and improve worker convenience of the blasting work.

Provided is a blasting system including a first detonator and a second detonator and a user terminal. The user terminal performs wireless communications with the first detonator and wired communications with the second detonator. Each of the first detonator and the second detonator includes an electric detonator storing detonator information, in which the electric detonator ignites an explosive in response to a blasting command, a connector connecting the electric detonator to the user terminal via a wireless or wired communication means, and a wiring portion connecting the electric detonator and the connector.

Disclosed is a system for assisting blasting. The system includes at least one wireless blasting-related device that is deployable or deployed proximate to or within a portion of physical media intended to be blasted as part of a commercial blasting operation. The blasting-related device includes a device-based magnetic induction (MI) signal receiver with a magnetometer configured for through the earth (TTE) MI communication, and the blasting-related device includes a device-based MI signal source with a device-based antenna configured for TTE MI communication. The device-based MI signal source is configured to communicate with a vehicle-based MI signal receiver in a blast support vehicle that includes a set of vehicle-based magnetometers.

A system, method, or apparatus for generating a blast plan that can receive blast data comprising geological properties of a blast site, blasthole parameters, and available explosive product. A pattern footage can be determined based on a relationship between the face height, the specific energy of the available explosive product, and the geological properties of the bench. The burden and spacing can be determined from the pattern footage.
