Problems solved by technology
However, in the actual application process, there are still some restrictive factors that seriously affect the implementation of safe excavation technology. Will increase the safety hazards of roof fall and collapse
With the development, resources are extremely scarce. Nowadays, most of the construction methods of mines are relatively backward, and the safety factor is also extremely low. The backward construction methods cause a serious waste of mining resources.

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] combined with Figure 1~5 , a construction method for developing mine resources in underground goafs or roadways in damaged areas, comprising the following steps:
[0026] (1) Set the route: select the developed roadway (D), and select the roadway that was originally mined or the unusable waste roadway as the roadway to be developed (E);
[0027] (2) Drilling and drilling: drilling from the inside of the developed roadway (D) to the direction of the roadway to be developed (E), and the direction of drilling i...

The invention relates to a construction method for exploiting mine resources in a tunnel of an underground goaf or destruction area. The construction method comprises the following steps of (1) setting a route; (2) conducting drilling and punching; (4) conducting grouting and filling; (5) conducting drilling and punching again; (6) conducting grouting and filling again; and (7) conducting circulating operation. In the step (1), when the route is set, a plurality of relative positions of tunnels to be exploited and exploited tunnels are arranged. In the step (2), a plurality of punching directions are provided during punching. In the step (3), the number of grouting pipelines is set to be multiple. By using the construction method provided by the invention, the tunnel can be safely and efficiently arranged and exploited in the goaf or the destruction area, the construction safety is high, the operability is high, and the construction method can be widely applied to randomly arranged andexploited tunnels in the goaf or the destruction area of mineral resources and then applied to the technical field of underground mineral resource development.
Description
technical field [0001] The present invention relates to the technical field of mining resources mining, and specifically refers to a construction method for exploiting mine resources in tunnels in underground goafs or damaged areas. Excavation construction plan. Background technique [0002] Mining resources are increasingly scarce and cannot be regenerated. There are still 30% to 70% of the mine resources in the goaf or damaged areas left over from the past mining methods. Over time, the serious natural damage in this part of the area cannot be restored. With the rapid development of industry, mineral resources are gradually exhausted. In this case, it is particularly important to ensure the feasibility and safety of the construction technology during the construction process by rationally arranging the roadway and ensuring the exact implementation of relevant national policies. [0003] At present, my country advocates the construction of green and environmentally friend...
