Embodiment 1

[0033] Such as Figure 1-Figure 4 As shown in the present invention, a highly permeable filling retaining wall for a mine underground includes a surrounding rock 1, a waste rock layer 2, a permeable concrete layer 3 and a permeable brick layer 4 laid in sequence from bottom to top in the surrounding rock 1 , and the waste rock layer 2, the permeable concrete layer 3 and the permeable brick layer 4 divide the interior of the surrounding rock 1 into a port 5 and a goaf 6, and a number of permeable pipes 7 are embedded in the waste rock layer 2; A group of water permeable holes 8 are arranged on the side wall of the water permeable pipe 7 close to the goaf 6, the outer ends of the water permeable holes 8 are connected with a filter layer 9 provided with mesh openings, and the inside of the water permeable pipe 7 and the water permeable holes 8 are respectively filled with There is a water-absorbing block 10 made of water-absorbing material, and the permeable pipe 7 is provided wi...

Embodiment 2

[0042] Such as Figure 5 As shown, the inside of the ejector rod 32 is provided with a water-absorbing groove that runs through both ends of the top, and the inside of the water-absorbing groove is filled with a water-absorbing strip 34 made of water-absorbing material; The water in the filter layer is absorbed, which increases the drainage area of ​​the slurry. At the same time, the shaking block 29 drives the ejector pin 32 to scrape off the slurry impurities on the surface of the ejector pin 32 when the mesh opening of the filter layer 9 moves back and forth, reducing the impact of the slurry on the top. The end of the water-absorbing strip 34 at the outer end of the rod 32 is blocked, resulting in a reduced effect of the water-absorbing strip 34 on absorbing water in the slurry.

[0043] A construction method for a strong water-permeable filling retaining wall in a mine, the method is applicable to the above-mentioned filling retaining wall, and the steps of the method are...

Abstract

The invention belongs to the technical field of mine filling mining, and particularly relates to a mine underground high-water-permeability filling retaining wall and a construction method thereof.The mine underground high-water-permeability filling retaining wall comprises a waste rock layer, a water-permeable concrete layer and a water-permeable brick layer, and a plurality of water-permeable pipes are pre-buried in the waste rock layer; a group of water permeable holes are formed in the side wall, close to the goaf, of the water permeable pipe, the water permeable pipe and the water permeable holes are filled with water absorption blocks made of water absorption materials respectively, and a water squeezing assembly is arranged in the water permeable pipe; water in surrounding slurry is efficiently absorbed through the water absorption blocks arranged at the water permeable pipes and the water permeable holes, meanwhile, a worker can extrude out the water absorbed in the water absorption blocks through work of the water squeezing assembly, the water discharging efficiency and quality of the water permeable pipes for the water in the slurry are greatly improved, the water permeability of the filling retaining wall is enhanced, and the filling retaining wall is convenient to use. Therefore, the gelling time of the filling slurry is shortened, the filling period of the filling slurry is shortened, and the filling quality of the slurry is improved.

Description

technical field [0001] The invention belongs to the technical field of mine filling and mining, and in particular relates to a strong water-permeable filling retaining wall under a mine well and a construction method thereof. Background technique [0002] The filling mining method has significant advantages such as reducing solid waste discharge, improving ore recovery rate, and controlling stope pressure. It is a mining method with great development prospects and has been more and more widely used in the world. The filling retaining wall is an extremely important part of the filling method. Its main function is to block the overflow of the filling slurry in the goaf and to discharge the slurry water in time. In order to obtain high filling quality and efficiency, the filling retaining wall must have good water permeability so that the filling slurry can quickly set. At the same time, in order to reduce the filling cost, the cost of the filling retaining wall should be rela...
