Blasting engineers often struggle with equally distributing explosive charges over a long blast hole using traditional methods. Our Flexible Liners address this issue by ensuring even charge distribution across extended lengths. These liners offer flexibility in diameter and length, making them a versatile and effective solution for efficient blasting.
Rigid Liners effectively distribute explosive charges over a longer length of the blast hole, addressing the limitations of traditional solutions.
Our Spacers are designed to maximise the energy of explosives, making them the best and most cost-effective solution for improving fragmentation and safety. They enhance fragmentation, reduce fly rock and explosives usage, and improve the powder factor, allowing you to utilise your explosives’ energy to the fullest. Our industry-leading, easy-to-transport Spacers come in various options based on diameter, length, waterproofing, and more.

Explosives can be wasted if they seep into cracks and crevices in rock formations. Using liners, decking, and controlled charge distribution prevents wastage by containing the explosives within the primary blast hole, enhancing efficiency and minimizing waste.
When charging in fractured rock, using smaller, controlled charges helps prevent explosives from escaping into cracks. Tailored charge sizes and using are effective in managing fragmentation in fractured rock.
In highly fractured rock, a combination of liners and controlled, segmented charging is essential to ensure that explosives stay contained in the blast hole. This approach minimizes wastage and enhances the effectiveness of each blast.
For collapsing holes, consider using casing or drill-hole liners to maintain hole integrity. Fast-loading practices and specialized stemming materials also help keep the blast hole open long enough for effective charging and detonation.
Liners prevent explosives from seeping into cracks, ensuring they stay within the intended blast zone. This containment improves the efficiency of each charge, helping reduce overall explosive usage while maintaining blast effectiveness.
Liners provide a stable boundary within the blast hole, allowing for more consistent charge placement and distribution. This results in uniform energy distribution, enhancing fragmentation while reducing the likelihood of uneven blast results.
For vertical blast holes, using stabilizing liners and casing can prevent hole collapse. Fast, sequential charging also helps reduce the risk of collapse in these holes, improving charge placement accuracy.
Preventing collapse in vertical drill holes requires using high-quality casing materials, rapid loading techniques, and sometimes a combination of liners or stabilizers. These methods are especially effective in maintaining hole integrity in soft or unstable ground.
Inclined holes are prone to collapse, especially in fractured or loose ground. Using liners and temporary casings can stabilize these holes, ensuring accurate explosive placement and reducing the risk of collapse during charging.
Liners keep explosives contained within the designated blast hole, reducing waste and preventing seepage into cracks. This not only improves blast efficiency but also saves on the cost of explosives, optimizing resource use for each blast.
