Description

Technical Field

[0001] The utility model relates to the technical field of mining engineering, in particular to a coal mine tunnel rapid support template. Background Art

[0002] In the coal mining process, tunnel support is one of the key measures to ensure the safe operation of the mine. With the increase in coal mining depth and changes in the working environment, traditional tunnel support methods face many challenges. Conventional support methods usually use wooden supports, steel pillars, and concrete formwork. However, these support structures often cannot provide continuous and stable support when faced with complex geological conditions and strong ground stress. In addition, traditional support methods often require a long installation time during the construction process, and the adjustment, disassembly, and transportation of the support formwork are relatively cumbersome, which is not conducive to improving the efficiency and safety of coal mine operations.

[0003] The existing tunnel support technology still has the following problems: 1. Insufficient stability of the support structure: In some soft formations or high-stress working environments, traditional support structures are prone to displacement or deformation, and cannot effectively resist the deformation or collapse risk of the tunnel wall, affecting the safety of the mine; 2. Complex installation and adjustment: Traditional support systems are usually composed of multiple components. Installation and adjustment require a lot of manpower and material resources, and errors are prone to occur during the process, resulting in unsatisfactory support effects. In addition, the disassembly, movement and storage of support templates are relatively cumbersome, and a lot of time and resources are wasted; 3. Poor environmental adaptability: Existing support template designs are usually fixed and cannot be flexibly adjusted according to different tunnel shapes or geological conditions. Therefore, when faced with complex or special geological conditions, the support effect is unsatisfactory. Therefore, a coal mine tunnel rapid support template is needed to solve the above problems.
