A blasting system which is established using an autonomously controlled vehicle to traverse a blast site, moving from blast hole to blast hole and at each blast hole using robotic means to prepare each blast hole for detonation.

Method of and apparatus for establishing a blasting system

A blasting system including a plurality of detonators located in respective boreholes, which is implemented through the use of a remotely controlled vehicle used for survey purposes and for locating geographical positions of the boreholes.

Use of a remotely controlled vehicle in a blasting operation

A method of implementing a blasting system wherein positional information relating to a blast site is generated by a device which inputs the information to a processor which generates information pertaining to the location of each potential borehole at the site and that information is used by the device to indicate the location of each borehole to an operator.

Blasting system control

A signal is injected into a wired series of detonators to obtain a reflected signal which represents a validated status of the system. The reflected signal is compared to a second reflected signal, generated in a similar way, some time later; to detect factors which affect the validated status of the system.

Detonator system confirmation

A device for use in a blasting system which Includes a plurality of detonators, wherein the device Includes a connector for making a connection between the detonator and a harness in the blasting system, wherein the connector includes a housing and at least one Identifying source on the housing operable to emit an identifying signal thereby to Identify the physical location of the housing.

Detonator identification and timing assignment

A detonator system which includes an array of a plurality of discrete time delay relays () connected in series to one another, and a plurality of detonators () which are respectively connected to the array at spaced intervals ().

Detonator system

A blast key which includes a body and a blast energy generator in or on the body. The blast key may include a body in the form of a small housing and may further comprise a switch connected to the energy generator.
