Description

Technical Field

[0001] The utility model belongs to the technical field of mine mining auxiliary equipment and relates to a supporting equipment for assisting mine mining. Background Art

[0002] At present, the underground tunnel mining field adopts the shallow hole ore retention method for excavation. During the operation, the workers mine the ore body from bottom to top in layers. After each layer of ore collapses, they stand on the collapsed ore to continue drilling and blasting the higher layers of ore. In order to improve the excavation efficiency, traditional reinforced concrete support is not installed, and only protective gear is worn by the personnel, resulting in the following major problems in the underground tunnel mining field:

[0003] Due to the complex geological conditions and uncontrollable blasting operations in underground tunnels, it is often difficult to keep the working surface regular. In order to improve the working efficiency and continue working, safety protection is not added in time, which increases the risk of rockfall on the working surface and the top. Once a rockfall accident occurs, it may cause serious injuries or even life threats to the workers.

[0004] The traditional reinforced concrete support method requires secondary construction of the site. The construction process is complicated and cumbersome, and professional personnel are required to carry out the construction work. In addition, it takes a long time for the concrete to solidify and reach the required strength. Correspondingly, the time, manpower and installation costs are high, which does not meet the current actual operation needs and is inefficient.

[0005] Mineral mining is fundamentally different from tunneling. Mining is not a standard working surface. The size of the ore vein has an impact on the operation. Based on the geological conditions of underground tunnel mining sites and the diversity of working surface shapes, standardized support systems often cannot meet the actual needs of the site. Standardized support has high requirements for the applicable environment and lacks flexibility. In the actual construction process, the support system needs to be continuously adjusted and optimized according to the site environment to ensure its stability and safety.
