Abstract: Systems for delivering explosives with variable densities are disclosed herein. Methods of delivering explosives with variable densities and methods of varying the energy of explosives in a blasthole are disclosed herein.

Abstract: Emulsion explosives with gas bubbles that are resistant to in-borehole migration or coalescence are disclosed herein. Such emulsions can be sensitized by mechanically-introducing gas bubbles into the emulsion. Resistance to gas bubble migration and coalescence can be achieved by homogenization, without the need for bubble stabilization agents.

Abstract: A blasthole guard may include a conduit and a cap. The conduit is sized and shaped to allow a hose to pass through. The cap comprises a funnel that narrows to an open end of the conduit. A slot continuously extends from the conduit through the cap such that the slot forms an opening that extends along an entire length of the device.

Abstract: A blasting control system includes a detonator module, and a blasting machine interface configured for serial communication between a blasting machine and the detonator module. The detonator module includes a detonator, a unique electronic ID, a switch configured to enable/disable the detonator in response to verification of the unique electronic ID, a communication device configured for communication with the blasting machine interface, and a processor responsive to instructions from the communication device. The blasting machine interface includes an I/O device, a communication device, and a processor responsive to the I/O device and the communication device. Upon verification of the unique electronic ID via communication from a user via the blasting machine interface, a state of the switch associated with the detonator is placed in an unlocked mode so as to enable activation of the associated detonator upon a fire signal from the blasting machine via the blasting machine interface.
