12g/M Petn Core Load Detonating Cord

Description

12 g/m PETN Core Load Detonating Cord – Reliable Linear Explosive for Controlled Blasting

Market Overview

Detonating cords are widely used in mining, tunnelling, and demolition operations due to their ability to deliver a precise, continuous explosive transfer line. With a core load of 12 grams of PETN per metre, this cord strikes a balance between reliability and manageable explosive power, making it suitable for medium-to-large blasting applications.

The demand for detonating cords continues to grow globally as industries prioritise efficiency, compliance, and environmental safety. PETN-based cords remain essential in both civil and mining projects because of their versatility, stability, and effectiveness.

Applications & Benefits

Mining Operations

Detonating cords are vital in open-pit and underground mines for initiating multiple charges simultaneously. The 12 g/m PETN cord ensures predictable energy transfer, supporting fragmentation control and operational safety.

Quarrying

In quarry blasting, the cord provides reliable initiation across rows of boreholes, improving fragmentation and reducing oversize rock.

Tunnelling

For controlled excavation in tunnels, the cord supports precise sequencing, minimising ground vibration and structural impact.

Demolition

Authorised demolition teams use detonating cords in engineered sequences to achieve predictable results while ensuring safety and compliance.
