Using liners and spacers help control the blast radius and fragmentation, ensuring efficient fragmentation and minimizing the risk of damage due to excessive vibrations by better charge distribution.

Blast Hole Liners

Uttam Blastech manufactures high quality Blast Hole Liners of different diameters to create a barrier between the drill hole and the explosives. Using a blast hole liner effectively reduces the quantum of explosives and contains the explosive from leaching into the rock around the blast hole. The liners also help in creating an effective barrier between the moisture in the drill hole and the explosives in order to create maximum blast efficiency.

Blast Hole Spacers

During blasting operations, spacers can be used, along with liners to maintain the desired distance between explosive charges. Using blast hole spacers also reduces fly rocks, improves powder factor and helps you maximise the effectiveness of blasting, thereby reducing the overall cost of production.

Liners and Spacers from Uttam Blastech come in varying lengths and diameters. You can also choose single wall liners and double wall liners with an optional anti-static coating. The liners are available with both flexible material as well as rigid materials
