Friction Bolt Mining Systems

Friction Bolt mining systems are a type of rock reinforcement method used in underground mining operations to support excavations and prevent rockfalls or collapses.

Friction Bolt mining systems are commonly used in underground mining operations where ground conditions are poor or unstable. They are particularly effective in areas where traditional support methods, such as timber or steel sets, may be impractical or insufficient. Friction bolts  can be installed quickly and easily, making them a popular choice for temporary or permanent rock reinforcement.

● Friction Bolts

Friction Bolts are typically steel tubes that are longitudinally split along their length. They are installed by inserting them into predrilled holes in the rock. As they are inserted, the split portion of the tube expands, exerting pressure against the rock walls. This pressure helps to support the surrounding rock mass and prevent it from collapsing.

● Friction Bolts

Friction bolts, also known as friction rock bolts or expansion shell bolts, are another component of Friction Bolt mining systems. These bolts consist of a steel rod with an expandable shell at one end. Similar to Friction Bolts, friction bolts are installed by inserting them into predrilled holes in the rock. Once in place, the shell is expanded, creating friction between the bolt and the surrounding rock, which helps to provide additional support.
