Mine roof support as a support tool has undoubtedly 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 mine roof support must also be guaranteed during its use stability. After all, "safety and stability" is the foundation of all projects. Many mine roof supports on the market occasionally cannot avoid the instability, so what are the reasons for this phenomenon? Today we will take a look together so that everyone can be perfect and foolproof in use!
A lot of engineering practice shows that in the high-stress soft rock roadway, the high-resistance shrinkable mine roof support is unstable and damaged. In addition to strength reasons, mine roof support is more structural instability. There are many reasons for this. In summary, there are three main reasons:
1. The strength of the connector on the top of the mine is low, or the structure of the connector is unreasonable, which causes the mine roof support to be unstable;
2. Poor interaction between surrounding rock supports, which leads to poor stability of the roof support structure of the mine;
3. Mine roof support does not adapt to the deformation characteristics of roadway surrounding rock, resulting in structural instability of the mine roof support.
As the leader in the mining industry, the mine roof support is widely recognized by the market and recognized by customers. The three words "professional, dedicated, and expert" are a high-level summary of its product quality and performance. Welcome everyone to consult and visit.
