DEVICE FOR DETERMINING FAILURES AT ELECTRIC BLASTING Russian patent published in 2012 - IPC F42D5/02 

FIELD: blasting operations.

SUBSTANCE: device for determining failures at electric blasting includes control elements, counting set and start-up scheme with blasting counting At that, device is also equipped with a matching unit and information input and display device. As the counting set there used is microcontroller; as the recording elements there used are voltage and current sensors, and as start-up scheme there used is electric blasting circuit closing sensor. At that, inputs of current and voltage sensors are connected to main wires of electric blasting circuit, and outputs are connected to the matching unit the outputs of which are connected to microcontroller input; at that, input of closing sensor is connected to the blasting instrument, and output of closing sensor is connected to microcontroller.

EFFECT: improving safe and fail-free operation owing to controlling the amount of energy absorbed with electric blasting circuit during the initiation.
