Method for increasing volume of tailings pond for mine enterprise

Abstract

The invention discloses a method for increasing the volume of a tailings pond for a mine enterprise. The method for increasing the volume of the tailings pond for the mine enterprise comprises the steps that a dam in an original dam is constructed on the portion, away from the original dam by a proper distance, of a tailings body, at least one set of rapid dewatering and solidifying system is arranged in the dam in the original dam and located inside the portion, below the dam in the original dam, of the tailings body, and tailings water in the dam in the original dam and inside the portion, below the dam in the original dam, of the tailings body is collected and discharged out of the original dam through the rapid dewatering and solidifying system. According to the method for increasing the volume of the tailings pond for the mine enterprise, the dam is constructed on a middle-and-later-stage old tailings pond according to the center line type dam construction method, and then the volume is increased greatly. According to the principle of the method, the construction space and the favorable topographic conditions which are not utilized by upstream dam construction are fully utilized, the final-stage elevation of the dam constructed in the original dam is increased, the area and the volume of the tailings pond are increased, the volume of the tailings pond can be generally increased by one time to three times, and the service life can be prolonged to over five years to ten years.

Description

technical field [0001] The invention relates to a method for expanding the capacity of tailings ponds of mining enterprises. Background technique [0002] Since the beginning of the 21st century, most mining enterprises are increasingly facing a problem, that is, one tailings pond has been used to the middle and late stages, and the second tailings pond and the third tailings pond have to be rebuilt. A new tailings pond has to be rebuilt. However, for the new tailings pond, the land resources are no longer what they used to be, and it is almost impossible to expropriate large areas of land, and the infrastructure investment costs are huge. Then there is only one way left, which is to heighten and expand the old tailings storage. However, since most of the current tailings ponds adopt the upstream dam construction, the dam body contains multiple layers of mud interlayer, the dam body has a high infiltration line, and the structural strength is low. dam, so the expansion is...

AI Technical Summary

Problems solved by technology

However, the old tailings body is at the edge of the infiltration line, and there are unsafe and unstable factors. It is necessary to eliminate potential safety hazards in order to truly realize the construction of the dam within the dam
