A Combi Plate for friction bolts is a specialized component used in mining and tunneling operations to enhance the installation and performance of friction bolts, which are rock reinforcement devices. 

Purpose and Functionality of Combi Plates

Integration and Support: It provides a stable base for anchoring friction bolts into drilled holes within rock formations. The plate ensures that the friction bolts are securely fastened, thereby enhancing the structural integrity and stability of underground excavations.

Load Distribution: Similar to other types of dome plates, the Combi Plate distributes the load exerted on the friction bolt uniformly across the rock surface. This helps to minimize stress concentrations and reduces the risk of rock failure or collapse.

Versatility: Combi Plates are designed with versatility in mind, often featuring multiple attachment points or interfaces. This allows them to accommodate various friction bolt sizes and configurations, adapting to different mining and tunneling requirements.

Combi Plate Features

Material and Construction: Typically made from durable materials such as steel, Combi Plates are designed to withstand the harsh conditions encountered in mining environments.

Installation Ease: They are engineered for straightforward installation, often including pre-drilled holes or standardized dimensions that streamline the assembly process.

Compatibility: Combi & Duo Plate are compatible with different types and sizes of friction bolts, ensuring compatibility across various mining and tunneling applications.
