Introduction of Mine support bracket:
Mine support bracket is the core support equipment for the integrated expansion and security operation of the comprehensive mining working face. It is installed in the integrated expansion and security tunnel, and can provide temporary support for the unsupported roof area during the excavation construction and hydraulic support installation process. Mine sliding support adopts a multi-mode intelligent control system, which supports manual operation, wireless remote control and remote centralized control. Through cross support and alternating forward movement technology, the continuity of support operation is achieved, ensuring that the roof is always in an effective support state, preventing the roof from sinking due to the movement of Mine sliding support, saving support materials, and effectively solving the roof control problem during the installation of large-section tunnels.
Features of Mine sliding support:
1. Underground support supports adopts modular design, and the installation and disassembly process is faster.
2. Due to its structural characteristics, underground support supports has a strong bearing capacity and can support the tunnel for a long time.
3. Underground support supports are made of high-quality materials and can be used repeatedly for a long time.
4. Underground support supports can be remotely controlled to reduce the risk of personnel exposure in dangerous areas.

Application of Underground support supports:
1. Installation/withdrawal channel of comprehensive mining working face: During the installation or withdrawal of hydraulic supports, the exposed area of the roof is large and the empty roof time is long. Underground support supports can provide temporary protection to prevent the roof from sinking.
2. Excavation and expansion of large-section tunnels: Mine sliding supports can work in coordination with tunnel boring machines to reduce the empty roof distance.
3. Working face end and advance support area: Mine sliding supports can adapt to the movement needs of large equipment such as transfer machines and crushers, and dynamically adjust the support position.
4. Support for special geological conditions: such as soft roof, cracked rock formations or high stress impact ground pressure areas.
5. Quick installation and emergency rescue: Mine support bracket can quickly form a supported rescue tunnel, and remote control operation reduces the number of people entering dangerous areas.
