What is known as a "trunkline" in the context of detonating cords?

Explanation:
In the context of detonating cords, a "trunkline" refers to the main section of the detonating cord to which either branchlines and downlines are attached. This configuration allows for a controlled and coordinated detonation of explosives, facilitating a simultaneous or sequential blast effect across multiple charges connected to the trunkline. By using a trunkline, blast patterns can be effectively managed to optimize fragmentation and minimize vibrations. Understanding the role of the trunkline is crucial for blast design and execution in mining operations, ensuring that all explosives are detonated in a manner that enhances safety and efficiency.
