Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to an artificial false bottom structure and a mining method. Background Art

[0003] With the development of underground mining technology in metal mines, the filling method layered artificial false bottom mining technology came into being, aiming to solve the problem of high ore loss rate in traditional open-pit mining. Under this technical path, the ground pressure is controlled by leaving top and bottom pillars to ensure the safety of mining operations. Especially in mines with open-pit mining, due to the need to leave a large number of pillars, the ore loss rate is large, and high-grade pillars have not been effectively developed, resulting in a waste of mineral resources. The development of this technology aims to improve resource utilization and reduce ore loss to meet the requirements of sustainable development.

[0004] At present, the filling method of layered artificial false bottom mining technology has become an important method in underground mining of metal mines. This technology reduces the loss of ore by reserving an artificial false bottom in the cutting space to replace the traditional pillar support. However, in the existing technology, if an artificial false bottom needs to be reserved, it is usually necessary to prefabricate reinforced concrete structures in the cutting space. This process not only consumes a large amount of steel, cement and labor, but also requires long-term maintenance after prefabrication to ensure that the strength of the reinforced concrete meets the standards. This traditional method of making artificial false bottoms has a huge waste of resources and labor, and also affects the efficiency of mining.

[0005] In the prior art, when using the filling method to carry out mining operations with a layered artificial false bottom mining technology, the traditional reinforced concrete artificial false bottom is filled in the mining channel of the stope, and it is completely filled in the tunnel where the ore excavation has been completed. In this way, although the purpose of mining can be achieved by filling the tunnel, in the actual operation process, if the tunnel is completely filled, the mining cannot be fully realized. If the excavated tunnel is reserved during the filling process, the stability of the tunnel will be affected. It can be seen that the filling method in the prior art affects the production efficiency of the mine because of the need to reserve the tunnel when filling the tunnel in the mine.
