Abstract
The invention discloses a spatial isolation type runway pavement underlying goaf treatment method and relates to goaf treatment in the fields of mining engineering, civil engineering, traffic engineering and the like. The goaf treatment method aims to solve the problem that the number of underlying excavation roadways is large, and the roadways may be communicated with one another. A plurality of investigation sections are arranged by excavating, digging and investigating a level, it is guaranteed that a reinforcing project is totally within a determined goaf range, an isolation structure is arranged on the boundary of a continuous goaf, and therefore it can be guaranteed that all reinforcing filler is added and diffused within a definite range. The method overcomes the defect that slurry flows in disorder under unrestrained conditions in a conventional grouting filling goaf, and consequently it is difficult to guarantee that the slurry is effectively diffused within a definite range.

Globality, be difficult control to the STRESS VARIATION of country rock, there is potential safety hazard, and the method quantities is huge, costly.Second
It is to carry out borehole or drilling to make concrete perfusion or serosity after goaf and extraneous insertion to plant, though this method can ensure to greatest extent
The integrity of country rock, but it is more and in the case of being mutually communicated in goaf, there is serosity unordered flowing under unconfined condition,
It is difficult to ensure that the defect that serosity is effectively spread in the range of restriction.
The content of the invention:
It is an object of the invention to when overcoming using conventional method slip casting filling goaf, it is difficult to ensure that serosity is limiting model
Enclose the defect of interior effective diffusion.For achieving the above object, the present invention provides following technical scheme:
Underlie goaf Treatment Methods in a kind of road face of spatial separation formula, it is characterised in that key step includes:(1) excavate
Prospecting tunnel, determines prospecting section in tunnel, detection of punching in section;(2) to the dead zone opening connecting passages for detecting;
(3) vertical reinforced concrete divider wall is set up across dead zone laying reinforced concrete vacation bottom on continuous dead zone border in designed elevation;(4) it is right
All isolation dead zones are filled consolidation process;(5) structure thicker road face.
Wherein step (1) determines prospecting section in prospecting gallery, and detection of punching in section is in one or more lanes
Arrange a prospecting section in road at a certain distance, punch perpendicular to mineral ore that flat inspecting hole of first fetching water such as proves that dead zone is present,
Then be directly perpendicular to mineral ore lane is tied to dead zone;Such as no dead zone, then lay to inspecting hole, if any dead zone, then beat to inclined shaft
Visit to dead zone;Finally stamp to inspecting hole, if any dead zone, then make a call on one and visit to dead zone to inclined shaft.These lead to mineral ore gallery and
Inclined shaft can punish passage as dead zone.As three directions there all are not discovery dead zone, then continue to drill next prospecting section,
By that analogy, finally can ensure that all of reinforcing engineering completely it is determined that dead zone within the scope of;
Step (4) is to carry out slip casting (cement mortar or cement mortar) using surface drilling or well lane engineering to the dead zone for isolating
Filled, so can ensure that all reinforcing implants in the range of restriction are filled and spread;
After the completion of step (5) is dead zone reinforcing engineering, viaduct structure thicker road face is laid on ground, such that it is able to guarantee i.e.
Make, in the case where there is slight movement dead zone of underliing, also to can guarantee that the safety and stability in overlying structure road face.
It is of the invention compared with original conventional slip casting fill method, accurately can limit slip casting filling region, overcome
As empty interval is mutually communicated, conventional grouting method is difficult to ensure that the defect that serosity is effectively spread in controlled range.

Specific embodiment:
For making the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, to this
Invention is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, not
For limiting the present invention.
In embodiment, it is flourishing that certain large-scale road face engineering plans to build regional historical mining industry, due to Privately operated mines well it is planless
Mining data, and disorderly adopt random digging phenomenon seriously, cause the distribution in goaf disorderly and unsystematic.Underlie in the range of whole construction and excavate lane
Up to as many as 20,000 m, dead zone is in disordered state in spatial distribution and has good connectivity in road, if using conventional slip casting filling
Goaf, serosity is under unconfined condition by unordered flowing, it is difficult to ensure that serosity is effectively spread in the range of restriction, so as to reach not
To expected consolidation effect, if especially ready-built structure road face dead zone of underliing timely and effectively can not be processed, certainly will be right
