Embodiment Construction

[0036] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than an exhaustive list of all the embodiments. Also, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.

[0037] The present application relates to a shielded well digging method. In the shielded well excavation method, first, step S01 is performed, and the roadway is segmented according to a preset length in the length direction of the roadway design. like figure 1 shown, the figure 1 Two segments along the length of the roadway are given. Then, step S02 is performed, and construction operations are sequentially performed on the divided sections. For example, in...

Abstract

The invention provides a shield type well digging method and a water drainage device, and the shield type well digging method comprises the following steps: S01, segmenting a roadway according to a preset length in the designed length direction of the roadway; s02, construction operation is conducted on the divided sections in sequence, and the construction operation of each section comprises the following sub-steps that S021, drilling detection is conducted on a roadway top plate so that advanced detection work can be conducted, and S022, roadway well digging is conducted after advanced detection work is completed, in the sub-step S021, drilling detection is conducted through a directional drill, and in the advanced detection work process, drilling detection is conducted through a directional drill; according to a detection result, the top plate is treated firstly when the top plate needs to be treated, the safety of roadway well digging in the step S022 is guaranteed, advanced detection is adopted in the shield type well digging method, the roadway tunneling area is detected through directional drilling, and a safer construction environment is provided for later tunneling.

Description

technical field [0001] The invention belongs to the technical field of mine excavation, and in particular relates to a shielded well excavation method and a water drainage device. Background technique [0002] Mine refers to the mines that are mined underground. Sometimes the inclined shafts, shafts, flat tunnels, etc. in the underground development of mines are also called mines. The development of mines has a significant and far-reaching impact on the overall production and construction of metal mines or coal mines. , it is not only related to the amount of infrastructure works, initial investment and construction speed of the mine, but more importantly, it will determine the production conditions and technical and economic indicators of the mine in the long run. . [0003] At present, there are problems of limited drilling distance and scope for the exploration and production of aquifers in the well-drilling area in the market. Specifically, the drilling distance is sho...
