Friction bolts, also known as split set bolts, are widely recognized for their effectiveness in providing ground support across various industries. Their unique design and ease of installation make them a popular choice for stabilizing structures in challenging environments. This article explores the diverse applications of friction bolts, highlighting their versatility and reliability.
The mining industry is one of the primary users of friction bolts. These bolts play a critical role in ensuring the safety and stability of underground mines. Here are the key applications within the mining sector:
Roof Support: Friction bolts are used to stabilize the roofs of underground tunnels and shafts, preventing rock falls and ensuring the safety of miners.
Wall Reinforcement: They provide additional support to the walls of mine tunnels, preventing collapses and maintaining structural integrity.
Stoping: In mining stopes, friction bolts help secure the rock mass, allowing for safer extraction of ore and reducing the risk of rock bursts.
Friction bolts are extensively used in tunneling and other underground construction projects. Their applications in this field include:
Initial Ground Support: During tunnel excavation, friction bolts provide immediate support to freshly exposed rock, stabilizing the structure until permanent supports are installed.
Permanent Lining Support: They are often used in conjunction with shotcrete or concrete linings to enhance the long-term stability of tunnels.
Subway Construction: Friction bolts are employed in the construction of subway tunnels, ensuring safe and stable passageways for transportation infrastructure.
