Example Embodiment

[0018] Example 1:

[0019] The method includes the following steps:

[0020] 1) Treat the rough surface of the chamber with spray slurry. Use galvanized flat iron and nail gun to fix the waterproof board on the rough surface after treatment. The nail length is 35mm-50mm; the nail penetrates the waterproof board and fixes it to the rough surface. The large length ensures firm fixation.

[0021] 2) Fix a 50mm screen on the fixed waterproof board. The fixed area is equal to the waterproof board. The nail shot length of the fixed screen is 50mm-80mm; the nail shot length fixes the sun screen to the waterproof board. It is fixed to the rough surface through the waterproof board, and after the second tightening, the fixation of the drying net is increased, which is convenient to improve the subsequent initial spray and respray effects.

[0022] 3) Initial spraying: spray concrete with slurry on the fixed screen surface, the spray thickness is 5mm-20mm;

[0023] 4) Re-spraying: 20-30 hours a...

[0030] 3) Initial spraying: spray concrete with slurry on the fixed screen surface with a thickness of 5mm;

[0031] 4) Re-spraying: 24 hours after the first spray, it will be completely solidified, and then re-spray, the thickness is 50mm.

Abstract

A waterproof board isolation re-spraying management method for water leakage of an underground mine belongs to the field of underground mine water leakage management process. The method includes steps: firstly, using spraying slurry to spray rough faces of an underground chamber and fixing a waterproof board; secondly, fixing a 50mm screen onto the waterproof board by nails 50-80mm in length; thirdly, primary spraying, wherein the primary spraying thickness ranges from 5mm to 20mm; and fourthly, re-spraying, re-spraying after 20-30 hours when the primary spraying is completed, wherein the re-spraying thickens ranges from 30mm to 50mm. The top plate water leakage management concept of jamming in meet with water is broken through, and the method is remarkably effective according to constructional verification. Water leaked from the top plate is isolated by the waterproof board and flows in water grooves of a bottom plate through two sides of the waterproof board, forming of the underground chamber is unaffected, the waterproof board is effectively concealed, water leakage isolation is effective after integral construction, and construction is simple.

Description

technical field [0001] The invention provides a treatment method for isolation and re-spraying of water-proof panels in underground mines, and belongs to the technical field of water treatment in underground mines. Background technique [0002] After the horizontal air compressor chamber and the substation of the underground mine are excavated and formed, there is a lot of water (about 1.5 cubic meters per square meter). According to the requirements, the chamber must be watertight before equipment installation and debugging can be carried out. The method of plugging and leaking with filling materials, the method of spraying concrete with high-strength cement, and the method of grouting have been adopted for treatment, but all of them cannot achieve results due to the complexity and number of cracks, the large amount of water sprayed, and the scattered areas. Contents of the invention [0003] According to the above deficiencies in the prior art, the technical problem to b...
