Water drainage wall adopting brick structure and used in cut-and-fill stoping method

Abstract

A water drainage wall adopting a brick structure and used in a cut-and-fill stoping method comprises a wall body and geotechnical cloth arranged on the inner side of the wall body, wherein filling pipes and filling air-returning and water-returning pipes are arranged on the wall body; the wall body is built by bricks; intervals are reserved between the bricks and form water drainage holes; an observing hole is formed in the position close to the top of the wall body; and a man hole is formed in the middle of the wall body. The water drainage wall adopting the brick structure and used in the cut-and-fill stoping method is good in water drainage effect, not easy to block and low in cost, and has the firm wall body.

Description

technical field [0001] The invention relates to a drainage wall used in a filling mining method, in particular to a brick structure drainage wall. Background technique [0002] At present, most underground deposits at home and abroad are exploited by the filling mining method. During the stope filling process, in order to ensure the timely removal of excess water in the filling mortar, it is necessary to construct a drainage wall. The drainage walls currently used mainly include wooden structure drainage walls, steel The weaving drainage wall and the drainage wall formed by the concrete retaining wall + the drainage cage in the stope, among which the wooden structure drainage wall has the advantages of large effective drainage area and the stope can be filled after the construction is completed, but the cost is high, The construction quality requirements are high, and the larger the area of ​​the slab wall, the easier it is to deform, and the leakage of slurry is more seriou...

Problems solved by technology

[0002] At present, most underground deposits at home and abroad are mined using the filling mining method. During the stope filling process, in order to ensure the timely removal of excess water in the filling mortar, it is necessary to construct a drainage wall. The drainage walls currently used mainly include wooden structure drainage walls, steel The drainage wall formed by braided mesh drainage wall and concrete retaining wall + drainage cage in the stope, among them, the drainage wall with wooden structure has the advantages of large effective drainage area and the stope can be filled after the construction is completed, but the cost is high, The construction quality requirements are high, and the larger the area of ​​the slab wall, the easier it is to deform, and the leakage of slurry is more serious. The steel mesh drainage wall has the advantages of good drainage performance, low cost, and stope filling can be carried out after the construction is completed. However, on-site construction It is very difficult, and the larger the area of ​​the slab wall is, the easier it is to deform, and the leakage of slurry is serious. The drainage wall formed by the concrete retaining wall + the drainage cage in the stope has the advantage of no leakage of slurry, but it is prone to leakage during the filling process. Cages are clogged and costly
