Embodiment Construction
[0025] In order to further describe the present invention, a method of adding a drainage system in an existing tailings pond of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] figure 1 The schematic diagram of the drainage system that adopts the method of the present invention to be added in the tailings pond that is shown and combines figure 2 , image 3 , Figure 4 It can be seen that a method of adding a drainage system in the tailings pond of the present invention adopts the following technical solutions:
[0027] First, carry out detailed geotechnical engineering investigation on the area where the drainage system is to be added in the tailings pond, find out the engineering geological conditions of the stratum in this area, obtain the geotechnical physical and mechanical indicators required for calculation, and plan the location and location of the drainage well 2. The line of dra...

The invention discloses a method for additionally arranging a drainage system in a built tailing pond. Inner and outer layers of reinforced concrete piles (4) are annularly arranged below a reinforced concrete base (3); one reinforced concrete pile (4) is constructed and arranged below a circuit of drainage ducts (6) by every other a section of distance; a rubble cushion layer (7) is paved below the drainage ducts (6) not provided with the reinforced concrete piles (4); settling gaps (5) are arranged in the connecting places of the drainage ducts (6) and a drainage well (2); and after the drainage well (2) and the drainage ducts (6) are constructed, the tailing backfill is performed on the lower part of the drainage well (2) and the two sides of the drainage ducts (6) to form a tailing protective covering structure. The method solves the problem of needing to renewedly arrange the drainage system in the built tailing pond, not only can guarantee normal and safe production of critical tailing ponds, but also can continuously expand and use old tailing ponds, prevents site selection for new construction of tailing ponds, and is prominent in direct and indirect economic benefits.
Description
technical field [0001] The invention belongs to the technical field of tailings pond safety management, and specifically relates to a method for laying out a drainage system for tailings ponds, which is widely applicable to tailings ponds of various types and in various regions, and is especially suitable for conditions of heightening and capacity expansion, but limited It is used in large and medium-sized tailings ponds where the structural safety and drainage capacity of the drainage system do not meet the requirements. Background technique [0002] Tailings ponds are important safety production facilities in many mines, and their operating conditions are directly related to the production safety of mines and the safety of people's lives and property. In recent years, serious accidents of tailings ponds have occurred frequently in our country, which have caused great threats and damage to the society and people's lives and property. For example, on October 18, 2000, the t...
