FIELD: blasting.
SUBSTANCE: detonating cap comprises a vessel, which holds an igniter, a primary explosive and a secondary explosive arranged so that the igniter ignites the primary explosive, from which in its turn the secondary explosive detonates, an electronic timer of primary explosive ignition delay and an explosion initiation facility connected to the mentioned facility of primary explosive ignition delay. The explosion initiation facility comprises a shock wave tube, one end of which is fixed in the inlet part of the vessel, and a cylindrical sleeve installed coaxially with the shock wave tube, and forwarded to its side with an inlet into its cavity. In the cylindrical sleeve cavity there is a magnetic anchor capable of displacement along the axis of the specified cylindrical sleeve. At the outer side the cylindrical sleeve is embraced with an inductance coil.
EFFECT: higher accuracy of actuation and extended storage life of a cap.
