What type of blasting involves no electric components?

Non-electrical delay blasting is characterized by the absence of electric components in the initiation process. This method employs non-electric blasting caps, which are activated by shock tube or other non-electric means. The main advantage of non-electrical blasting is the improved safety it offers in environments where the risk of accidental detonation from stray electric currents is a concern. By using this method, operators can mitigate risks associated with electric blasting, making it a preferred choice in certain mining operations.

This type of blasting also allows for precise timing and sequencing of blasts through the use of delays in the non-electric detonators, contributing to enhanced control over the results of the blasting operation. Understanding this type of blasting is crucial for safety and efficiency in an underground mining environment, making it vital knowledge for a mine foreman.
