Abstract

The invention discloses a dump leaching field construction process based on a green mine construction technology, and belongs to the technical field of green mine construction. The leakage is prevented by additionally arranging an impermeable layer between two geomembranes, the impermeable layer adopts a honeycomb structure and has high pressure resistance, sealants are stored in honeycombs, whenstones penetrate from the bottom, the sealants can flow out to fill cracks of the lower geomembrane, a glass tube is broken under the puncture and extrusion action of the stones, so that lime powder and water are subjected to a chemical reaction, heat released by the reaction enables the water to boil to generate water vapor, then a sealing membrane is burst, nitrogen overflows from through holes,and the sealants are extruded out of the outer honeycomb to accelerate the flow-out speed and outflow volume of the sealants. Compared with the prior art, self-repairing of the geomembranes can be achieved, the leakage is prevented, and mine green production is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of green mine construction, and more specifically, relates to a construction technology of a heap leaching site based on the green mine construction technology. Background technique

[0002] Green mine construction is a complex system engineering, which represents the overall level and sustainable development potential of a region's mining industry development and utilization, as well as the ability to maintain the balance of the ecological environment. It focuses on scientific, orderly, and rational development and utilization of mine resources, and restores them to the greatest extent or transforms and innovates the inevitable pollution, mine geological disasters, and ecological damage imbalances.

[0003] Heap leaching sites are widely used to extract gold, silver, copper and other metals. When using this method, low-grade ores are piled up in the heap leaching site, and the heap leaching site uses geomem...
