Summary of the invention:
When the object of the invention is to overcome employing conventional method slip casting filling goaf, be difficult to the defect ensureing slurries effectively diffusion in limited range.For achieving the above object, the invention provides following technical scheme:
Underliing a goaf Treatment Methods in isolated face, road, space, it is characterized in that key step comprises: (1) excavation prospecting tunnel, determine to reconnoitre section in tunnel, punching detection in section; (2) to the dead zone opening connecting passages detected; (3) cross over dead zone in design elevation and lay the steel bar concrete false end, on border, continuous dead zone, set up vertical steel bar concrete divider wall; (4) filling consolidation process is carried out to all isolation dead zones; (5) face, structure thicker road.
Wherein step (1) determines that in prospecting gallery prospecting section is perpendicular to mineral ore punching, flat inspecting hole of first fetching water, and as proved, dead zone exists, then directly tie lane to dead zone perpendicular to mineral ore; As there is no dead zone, then laying to inspecting hole, if any dead zone, then beating and visiting to dead zone to inclined shaft; 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 the gallery of mineral ore and inclined shaft can be used as dead zone punishment passage.As three directions all do not find dead zone, then continue to drill next one prospecting section, by that analogy, finally can guarantee all stabilization workss completely within the dead zone scope determined;
Step (4) utilizes surface drilling or the dead zone of well lane engineering to isolation to carry out slip casting (cement paste or cement mortar) to carry out filling, can ensure that all reinforcing fillers are filled and diffusion in the scope limited like this;
Step (5) is after dead zone stabilization works completes, and lays face, viaduct structure thicker road on ground, even if thus can guarantee, when there is slight movement dead zone of underliing, also can ensure the safety and stability covering face, structure road.
The present invention, compared with original conventional slip casting fill method, can limit slip casting fill area accurately, overcomes because empty interval is mutually through, and conventional grouting method is difficult to the defect ensureing slurries effectively diffusion in controlled range.
