The steel mine support is used as a support tool, which will undoubtedly have a great impact on the safety of coal mine tunnels and other scenes. Therefore, the quality of the steel mine support is the top priority in the production process, and it must also be guaranteed during its use. Stability. After all, "safety and stability" is the foundation of all projects. Many steel mine supports on the market occasionally cannot avoid the instability, so what are the reasons for this phenomenon?
A lot of engineering practice shows that in high-stress soft rock roadways, high-resistance shrinkable steel mine support are unstable and destroyed. In addition to strength reasons, structural instability is more common. There are many reasons for this situation. In summary, there are three main reasons:
1. The strength of the steel mine support connector is low, or the structure of the connector is unreasonable, which causes the steel mine support structure to become unstable;
2. Poor interaction between surrounding rock support, which leads to poor stability of steel mine support structure;
3. The steel mine support does not adapt to the deformation characteristics of the surrounding rock of the roadway, resulting in structural instability of the steel mine support.
"Don't forget danger, don't forget worry, engineering plan, safety first!" Now that you know the reasons for the instability of the steel mine support, everyone must pay more attention to the use of Perform construction operations with an attitude!
