Protect Drilled Blast Holes with Hole Savers

 



Every drilled blast hole represents time, fuel and wear on the drill rig. If loose material falls back in before charging, the hole may need redrilling, which slows the whole blast schedule. Hole savers from FSP Oz Products fit into the collar of each hole, keeping dirt, rocks and debris out until the crew is ready to load. Made from blow moulded polyethylene, they suit open cut mines, quarries and construction blasting alike. 

How Hole Savers Protect Drill and Blast Work 

Drilled holes face plenty of threats between drilling and charging. Foot traffic, vehicle movement, drill rig impact and nearby blasts can all push material back into the hole or erode the collar. Wet conditions can also cause collar erosion and slumping inside the hole. 

Hole savers help keep the drilled depth intact and the collar in shape, which supports consistent charging and blast quality. They also act as a visual marker, warning people and vehicles that a drilled hole is there. Explosive hoses and leads are better protected during loading too. 

Sizes in the current range include: 

  • Hole Saver 65 for smaller diameter holes 
  • Hole Saver 75 for slightly larger bores 
  • Hole Saver 100 for mid sized blast holes 
  • Hole Saver 160 for larger diameter boreholes 
  • Hole Saver 200 for the widest blast holes 

Why Drill and Blast Teams Use Our Range 

FSP Oz Products has designed and manufactured heavy duty polyethylene products for mining since 1994. Hole savers come in a range of colours, so crews can colour code holes by type or stage of the blasting process. Branches in mining regions such as Mackay and Singleton support supply to nearby sites. 

Many units can be reused across several drilling cycles when they remain intact, which helps control consumable costs. Crews can inspect units for cracks or deformations before reuse. Covering open holes also reduces the chance of small animals falling in on remote sites. 

Mine sites and quarries value: 

  • Less redrilling after collar fallback or erosion 
  • Colour options for coding holes by stage 
  • Reusable designs that help lower consumable spend 
  • Clear visual warnings for people and vehicles 

Keep Every Drilled Hole Ready to Charge 

Sizes and colours are listed at https://www.fspaustralia.com.au/mining/hole-savers/ so drill and blast teams can match each diameter. Bulk orders for upcoming patterns can be quoted on request, while a spare supply on site avoids delays when new patterns are drilled. The mining team is on 1300 847 901 for advice on quantities and colours.
