A wireless electronic detonator includes an energy source and functional modules. A first switching switch is provided between the energy source and the functional modules, making it possible to connect or not connect the energy source to the functional modules. A control module for controlling the first switching means includes a module for recovering radio energy configured to receive a radio signal from a control console, to recover the electric energy in the radio signal received, to generate an energy recovery signal (VRF) representative of the level of electric energy recovered, and to generate as output a control signal (VOUT) as a function of the recovered energy, the control signal controlling the first switch.

Blasthole guards and related systems and methods

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.

NON-DETONABLE SHAPED CHARGE AND ACTIVATION
20200048997 · 2020-02-13 ·

A non-detonable shaped charge capable of becoming detonable upon activation. The shaped charge may be utilized for use with a perforating gun in oilfield applications. In this regard, during transport and other handling in advance of reaching the application site, the charge may be non-detonable. However, upon an intentionally directed activation, such as through heating, the shaped charge may be detonable.
