Centralized seepage drainage device for tailing pond and seepage drainage method thereof

Abstract

The invention belongs to the technical field of mine engineering, and particularly relates to a centralized seepage drainage device for a tailing pond and a seepage drainage method thereof. The centralized seepage drainage device for a tailing pond comprises an initial dam, a sub-dam and the like, and further comprises underground seepage drainage pipes, a seepage drainage well and the like, wherein the initial dam and a fill dam are arranged on the top of a foundation, the initial dam is connected to the tail end of the bottom of the fill dam, the sub-dam is arranged at the tail end of the top of the fill dam, a flood ditch is arranged among the sub-dam, the foundation and the fill dam, the underground drainage pipes are arranged on the two sides of the fill dam, a seepage drainage ditch is arranged on the foundation and located at the right end of the initial dam, the tail ends of the underground seepage drainage pipes extend into the seepage drainage ditch, the seepage drainage well is arranged in the flood ditch and communicates with the underground seepage drainage pipes through a pipeline, and a plurality of dam body seepage drainage pipes are arranged in the fill dam. The seepage drainage device and method achieve the effects that the seepage drainage effect is good, pipeline blockage can be avoided, the structure is simple, seepage drainage is centralized, and meanwhile the centralized treatment effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of mine engineering, and in particular relates to a centralized seepage discharge device and a seepage discharge method for a tailing pond. Background technique [0002] my country is a big mining country, and most of the tailings produced in the process of mine production and processing are discharged into tailings ponds for storage. At present, my country's tailings reserves exceed 10 billion tons, and 800-100 million tons of tailings are added every year. By the end of 2008, there were 12,655 tailings ponds nationwide, and 300 new tailings were added every year. Tailings ponds are one of the major hazards. Among the major disasters in the world, tailings pond disasters rank 18th after earthquakes, cholera, floods and hydrogen bombs. Therefore, the safety and stability of the tailings pond is extremely important, and the safety of the tailings pond mainly depends on the safety and stability of the tailing...

Problems solved by technology

[0005] In order to overcome the existing mine tailings due to its own characteristics, it is easy to cause the dam body to have a high soaking line, which seriously affects the safety of the dam body, and the seepage drainage device for this kind of impact cannot accelerate the speed of seepage drainage, and The drainage effect is not good. At the same time, the setting of the geotextile can make it clogged, that is, the geotextile is prone to obvious chemical clogging under the condition of alternating saturated and unsaturated conditions, so that the pipeline is prone to clogging. The invention provides a centralized seepage drainage device and a seepage drainage method for tailings ponds capable of good seepage drainage effect and avoiding pipeline blockage
