Abstract
An electronic blasting capsule which includes a housing which contains a propellant, a fuse, a sensor for detecting the position of the housing in a capsule delivery path, an energy arrangement for obtaining energy from an external energy source, and a controller, responsive to the sensor and the energy arrangement, for firing the fuse to initiate the propellant.
Claims12
An electronic blasting capsule which includes a cartridge, a propellant in the cartridge, an initiating device, an energy storage arrangement, a sensor for generating a signal which is dependent on the position of the capsule as it is moved along a predetermined path, and a controller which, in response to the signal, controls the supply of energy from the energy storage arrangement to fire the initiating device and so initiate the propellant.
A blasting arrangement which includes a drilling machine, a drill rod and a drill bit connected to the drilling machine, a pressurized source for directing a cartridge through passages in the drill rod and drill bit, and an external control unit which contains an external energy source, and wherein the external control unit is used to transfer, at least, timing information to the capsule to control firing thereof.
An electronic blasting capsule which includes a housing which contains a propellant, a fuse, a sensor for detecting the position of the housing in a capsule delivery path, an energy arrangement for obtaining energy from an external energy source, and a controller, responsive to the sensor and the energy arrangement, for firing the fuse to initiate the propellant.
