The MTi Group ROCKRIVETis a retentionplug for use in both underground and open pit mines. It works using friction and interferencegenerated bythe plastic fins in the ROCKRIVETto hold onto the wall of the hole. The fins are designed to closelike a collet givingmaximumholding capacity with minimalleaking. The design also incorporates spacesfor a downline or firing line to pass through, preventing the likelihood of cut-offs or misfires.
In underground mines, the product reduces slumping and minimises wastage on ANFO and emulsion. In open pit mines, the product is used fordecking and acts as a hole protector, ensuring no foreign material can enter the hole.It is installed by using a charge hoseor 1 ¼”splitthreaded pole adaptor with a ROCKRIVETCONNECTOR. Once the connector or hose is inserted onto the ROCKRIVET, it can be pushed tothedesired heightin thehole. To decouple the ROCKRIVETCONNECTOR,twist the poleand pull away. Once inplace, the ROCKRIVETwill hold in place ensuring no movement occurs.The SEMI-RIGID range is easier to install while the RIGID range has a larger holding capacity for larger loads.
