Blasthole lining for improving mining or tunnelling efficiency
Terraliner is a unique system which can be applied as a liner to stabilise blastholes. The liner forms a semi-rigid coating which follows the shape of the blasthole adapting it’s imperfect shape. The product is applied using a specific
spray application system suitable for upholes and downholes in underground and surface mining applications.
Maintaining the integrity of blastholes is an important factor in efficient mining operations. Blastholes may become blocked from movements in ground or rock fragments loosening from nearby blasting activities. Premature closure of blastholes means additional costs and delays are incurred in redrilling or blast performance is compromised with associated downstream cost impacts.
Terraliner is compatible with typical blasting agents used in the mining, tunnelling and construction industries. It has negligible impact on blast performance and is applied to dry and de-watered holes.
- The blasthole can be filled up to 6 months after drilling has been completed
- The membrane will protect the hole from intrusion of water
- Blasthole drilling programs can be executed seperately to blasting sequences
- Productivity and safety are improved
