Abstract

Improvements in electric safety baits for mines, for their protection against premature inflammation by parasitic electric currents, characterized by the fact that a safety device that short-circuits the rheofs of the electric device of inflammation, before it, together with a third wire in contact with the metallic hull of the bait, is coupled with the electric bait, especially the bridge type.
