| titleOfInvention | A kind of roof water-rich limestone aquifer water damage control method and construction method |
| abstract | The invention discloses a roof water-rich limestone aquifer water hazard treatment method and a construction method. The roof water-rich limestone aquifer water hazard rapid treatment method includes: arranging a treatment boundary around a target area to be treated, and the plane of the treatment boundary and the target area. The projection distance is at least R meters, and R is the diffusion radius of the slurry in the treatment area; the boundary plugging hole group is arranged along the treatment boundary and its extension direction; the internal treatment hole group is arranged in the area surrounded by the treatment boundary, and the internal treatment hole group is the same as the described Governance boundaries coincide and/or intersect. The invention uses ground directional drilling to carry out boundary sealing and internal transformation in the treatment area to achieve the purpose of quickly treating the roof water-rich limestone aquifer, and the roof water drainage is difficult to solve the situation of strong water-rich aquifer and large replenishment. The straight hole grouting or regional treatment method adopted by the traditional treatment technology has disadvantages such as high cost, long construction period, difficult construction, and tight working face replacement. |
