What is the development history of anchor rod support in China?
The research on anchor bolt support in China began in 1956 and was mainly used in coal mine tunnels. It was not until the 1990s that anchor bolt support began to develop rapidly. In recent years, the theory and development of anchor rod support in China have evolved from single anchor rod operation to joint action of anchor rod groups, giving rise to various forms such as end anchoring and extended anchoring. The anchoring forms have also evolved from cement mortar anchoring agents to resin anchoring agents, expansion shell anchoring, and other anchoring forms.
