Underground roof support as a support tool will undoubtedly have a great impact on the safety of coal mine tunnels and other scenarios, so the quality of this product 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 underground roof supports on the market occasionally cannot avoid the situation of instability, so what are the reasons for this phenomenon? Today we come to understand, so that everyone can use it to be perfect and foolproof!
The reasons for the instability of the underground roof support can be summarized, there are three main reasons:
1. The strength of the underground roof support connector is low, or the structure of the connector is unreasonable, causing the underground roof support structure to be unstable;
2. The poor interaction between the surrounding rock supports, which leads to poor stability of the underground roof support structure;
3. The underground roof support does not adapt to the deformation characteristics of the surrounding rock of the roadway, resulting in the structural instability of the U-shaped steel support.
"Do not forget the danger, don't forget the worry, the project plan, safety first!" Now that you know the reasons for the instability of the underground roof support, everyone must pay more attention to the use of Conduct construction operations with an attitude!
