Split Set Ground Support Functions
Split Set Ground Support is a frictional ground support system. When a split set is inserted into a drilling hole with a smaller diameter, the slot partially closes and the bolt diameter is compressed, which creates radial forces on the rock roof surface along the whole length and firmly holds the rock.
Thermal diffusion galvanizing is available for the friction bolt.
Split Set Ground Support usually combined with domed plates, provides anchoring force for rock strata.
Split Set Ground Support undergoes very stringent tensile testing to ensure product quality.
