Description
Damping through the nut in the casting resin anchor agent precisely to the role of stirring, and then pre-stressed.
Let pressure device in a high pressure situation, so that yield tube can be deformed to pressure, buffer and release the pressure of surrounding rock in order to protect against damage to the role of anchor. In order to get a safety of the laneway supporting.
