Problems solved by technology

[0004] During the construction of the heap leach field, due to the uneven surface treatment, the geomembrane is easily punctured by sharp stones, resulting in the leakage of the mother liquor, which leads to environmental pollution problems. Although there are currently composite membranes used to prevent leakage method, but the composite membrane can still be punctured, and the punctured part cannot be effectively repaired and filled

Embodiment 1

[0044] see Figure 1-7 , a heap leaching site construction process based on green mine construction technology, comprising the following steps:

[0045] S1. After other constructions are completed, level the site of the heap leaching site to remove sharp or protruding stones on the surface;

[0046] S2, laying the first layer of geomembrane 1 first, then laying the anti-seepage layer 2, and finally laying the second layer of geomembrane 1. The upper and lower sides of the anti-seepage layer 2 are fixedly connected with buffer pads 3, and the surface of the buffer pad 3 is fixedly connected with a plurality of adhesive balls 4, and the adhesive balls 4 play the role of connecting the anti-seepage layer 2 with the geomembrane 1 to prevent The anti-seepage layer 2 and the geomembrane 1 are dislocated and slipped. The anti-seepage layer 2 is composed of a plurality of outer honeycombs 201. The inner walls of the two sides of the outer honeycombs 201 are fixedly connected with the...

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...
