Introducing the LPD®

The most efficient way to achieve top, middle or bottom hole airdecks in large-scale production mining environments.

Why Use The LPD®?

Practical Flexibility

Achieve top, middle and bottom hole airdecks with just a single product. No extra tools required no matter which section of the hole needs an airdeck. Just Lock, Pop and Drop!

Zero On-Bench Assembly

Ready to use out-of the box, which means no messing around with separate parts on the ground, reducing any delays and allowing the bomb crew to focus on putting bomb in the ground.

Greater Portability

A small assembled footprint allows for a large number of LPDs to be stacked on the back of a light vehicle tray, increasing the efficiency in bulk application scenarios.

Reduced Labour Requirements

The high installation rates per hole does not impede regular loading progression. Blast crew can apply the LPDs to each hole in a matter of seconds.

Consistent Decking Depth

The LPD’s ease of application reduces human error commonly seen when using other products. No ropes or sand bags required and no mid hole blockages guarantees a high success rate every time.

Substantial Cost Savings

Immediately realize savings from a reduction in explosive usage costs while maintaining desirable blasting outcomes. Every LPD deployed represents a direct cost saving in explosive usage that offsets the cost of the LPD itself.

Increased Lump Return

Reducing undesirable fines content while maintaining optimal fragmentation distribution in the blast design.

Reduction in Fly Rock, Vibration & Greenhouse Gases

Decreasing volume of explosives used translates to a reduction in fly rock, vibration and greenhouse gases generated from each blast, decreasing the overall environmental impacts of blasting activities.

Frequently Asked Questions

What is the LPD® System?

The LPD device allows for rapid placement of an air-deck within a blast hole. The LPD is a device attached to a self-inflating gas bag that allows for one of three heights (0.5m, 1.0m & 1.5m)to be achieved simply by pulling the boot out and having it lock into place.

The Patent Pending concept is rugged, simple and reliable – creating an accurate air deck at a fraction of the install time of other decking devices.

What applications can the LPD® be used for?

The LPD can be used in any situation that requires an air-deck to be installed in the blast hole. This includes top-hole air-decking, mid-hole air-decking, and also bottom-hole air-decking.

Why would you choose the LPD® system over existing air-decking solutions?

Compared to existing air-decking solutions on the market, the LPD system has the lowest installation times, failure rates and broadest applications in tough mining environments.

What are LPDs® made of?

They are custom profile extruded plastic tubes, paired with stainless steel, non-sparking locking clips and a proprietary moulded plastic “boot” (end cap).

What is the purpose of the “boot”?

The boot serves 2 functions – to deflect the stick from catching the sidewalls of a blast hole, and to prevent the device from penetrating into the explosive product when applied in mid hole and top hole air-decking situations.

What are the advantages of air-decking?

The air-deck performs different functions at each location in the hole. Top-hole air-decking allows improved explosive energy distribution to break the hard cap/stemming zone on the surface and at the same time allows savings in stemming material. Mid-hole air-decking is used in double priming situations such as cavities, deep holes and powder factor reduction. Bottom hole air-decking can be used in large scale production mining to reduce the total amount of explosive in each column while maintaining floor conformance due to improved energy distribution.
