PVC Blast Hole Liners
Our blast hole liners are made with PVC pipe and are used to line the drilled holes in mining operations. A blast hole liner helps protect the explosive during the period between drilling and blasting by preventing loss of liquid explosive and by keeping water out of the blast hole.
Material: PVC
Dimensions: 2.125” O.D. x 1.75” I.D.
Threads: Flush joint thread male and female, 4TPI, or 8TPI
Uses: Exploration drilling holes to aid in the insertion and extraction of EM probes
Key Benefits of using Blast Hole Liners:
- Decreases leaching of explosives in the blast hole.
- The liner helps keep the explosives together, reducing potential separation to help create a more consistent blast as it causes all explosive material to detonate.
- Reduces loss of explosive by creating a barrier between the explosive and moisture in the blast hole.
