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!
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.
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.
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.
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.
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.
Reducing undesirable fines content while maintaining optimal fragmentation distribution in the blast design.
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.
Four Flags Blasting Technologies is an innovative mining startup company based in Western Australia.
Founded by 4 mining professionals with 40 years of combined industry experience, we have a collective passion for mining, a thirst for innovation, and a simple goal of creating products that are practical, cost-effective and adaptable to dynamic mining conditions.
With unprecedented challenges faced by the mining industry due to recent economic climates, there has never been a more important time to introduce innovations that provide significant cost reductions, are easily implemented and most importantly do not impede on productivity.
Four Flags Blasting Technologies develop products that are suitable for use in large scale mining operations. All products are carefully engineered for maximum efficiency, and have undergone significant field tests to ensure performance in actual mining environments.
We are constantly seeking new and innovative ways to improve on current industry best practices. Our continuous collaboration with large-scale mining operations allows us to maintain awareness of the difficulties faced in day-to-day operations, understand changing operational demands, and stay in-line with technological advances in the industry.
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.
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.
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.
They are custom profile extruded plastic tubes, paired with stainless steel, non-sparking locking clips and a proprietary moulded plastic “boot” (end cap).
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.
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.
