Abstract

The present invention discloses a method for collecting natural copper ore of non-ferrous metals, comprising the following steps: first, prospecting the ore layer; second, blasting and drilling the rock; third, excavating the mine; fourth, supporting the mine; fifth, mining and transporting the copper ore; sixth, recovering the ore pulp; and seventh, separating the ore pulp. The present invention relates to the field of mining technology. The method for collecting natural copper ore of non-ferrous metals separates the copper ore from the broken rock blocks during the excavation process, extracts the ore pulp generated during the excavation in a later stage for separate treatment, and uses a dedicated device to clean the drainage trough to avoid mineral precipitation.

By providing a drainage trough cleaning device, workers can clean the inside of the drainage trough when they change shifts and enter and exit the mine. The device is easy to push and clean quickly and easily, and the two modes are more convenient to use.

Description

Technical Field

[0001] The present invention relates to the technical field of mining, in particular to a method for collecting non-ferrous metal natural copper ore. Background Art

[0002] Copper ore refers to a collection of naturally occurring copper-containing minerals that can be used. Copper ore is generally composed of copper sulfides or oxides combined with other minerals. It reacts with sulfuric acid to produce bluish-green copper sulfate. Industrial copper minerals include native copper, chalcopyrite, chalcocite, tetrahedrite, azurite, and malachite. Over 280 copper-containing minerals have been discovered, but only 16 are major. The primary mineral mined in my country is chalcopyrite (a compound of copper, sulfur, and iron), followed by chalcocite and bornite. Natural copper minerals come in a variety of colors. Chalcopyrite is bright yellow, bornite is dark copper-red, and oxidizes to bluish-purple spots; chalcocite (copper sulfide) is lead-gray; covellite (copper sulfide) is indigo-blue; tetrahedrite is steel-gray; and azurite (formerly known as zenqing or azurite) is a vivid blue.

[0003] The existing method of mining copper ore is generally to simply transport the mined ore out. However, during the mining process, a lot of broken particles are mixed in the accumulated water and are easily settled. Even if the water is pumped out, the drainage in the existing mine generally flows out through the drainage grooves on both sides. It has basically settled during the outflow process. Therefore, the mineral content in the discharged water is also low and has no recovery value. However, in fact, the sediment still contains a large amount of minerals, so the mining is not thorough enough. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a method for collecting non-ferrous metal natural copper ore, which solves the problem that the ore pulp contains a large amount of ore, but most of it precipitates on its own during the discharge process, so the minerals in the discharged ore pulp cannot be effectively collected and extracted.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for collecting non-ferrous metal natural copper ore, specifically comprising the following steps:

[0006] Step 1: Mineral Seam Survey: Using artificial seismic exploration, seismic waves are used to evaluate the mining area's structural morphology, mineral seam faults, and water-richness of the aquifer. Spectral simulation, field spectrum measurement, and remote sensing image processing are then combined to model and analyze the entire mining area. Finally, multiple equally spaced areas are selected for small-scale blasting. Deep soil and rock samples are analyzed to determine metal content, and the areas with the highest and lowest metal content are identified to determine the mining plan.

[0007] Step 2: Blasting and drilling: In the selected area with high mineral reserves, use the method of fixed-point and quantitative blasting to blast the surface rock layer, then clean up the gravel, drill the rock in a small area in the blasting gap, and dig out the prototype of the mine;

[0008] Step 3: Mine excavation: After the mine outline is dug out, mechanical equipment is used to continue excavating inwards. At the same time, the side walls of the mine are shaped to maintain the arched contour, and drainage ditches are excavated on both sides of the ground;

[0009] Step 4: Mine support: Use reinforced concrete to erect support linings at equal intervals in the excavated mine, and use simple truss support connections between adjacent supports. Then, ventilation pipes and cables are set up based on the support structure.

[0010] Step 5: Copper mining and transportation: During the excavation process, the broken rocks along the way are sorted out, and the rocks containing copper ore are separated and retained. When the mineral location is reached, large rock drilling equipment is used to quickly crush the rocks. After the upper ore layer is dug through, small rock drilling equipment is used to mine the ore, and the ore is transported out. A water channel is artificially opened to collect the water in one place.

[0011] Step 6, slurry recovery: After disturbing the accumulated water in the lower mine, use a pump to pump it into the upper flat mine and discharge it into the drainage troughs on both sides. When workers change shifts, use special drainage trough cleaning equipment to clean the sediment inside the drainage trough. The water discharged from the drainage trough is concentrated in the water reservoir for sedimentation;

[0012] Step 7: Slurry separation: The accumulated water in the reservoir is pumped out from the bottom layer and discharged into the centrifuge for separation and treatment, and the ore particles are extracted and collected centrally.

[0013] Preferably, in step five, ordinary rock formations are directly opened using equipment such as an impact drill, and for harder rock formations, a high-speed water jet gun is used to cut the rock formation using a high-speed water line.

[0014] Preferably, in step six, the slurry in the two drainage troughs is first introduced into multiple diversion troughs for diversion before being discharged into the water reservoir to reduce the water flow rate.

[0015] Preferably, the drainage trough cleaning equipment in step six includes a main wheel, the center of the main wheel is fixedly connected to a central axis, and the surface of the central axis is rotatably connected to an I-shaped pushing frame located between the front and rear sides of the main wheel.

[0016] Preferably, the outer surface of the main wheel is fixedly connected with an anti-skid plow blade, and a plurality of anti-skid plow blades are equidistantly distributed in the circumferential direction, and the lower left corner of the U-shaped pushing frame is rotatably connected with an auxiliary wheel.

[0017] Preferably, the front side of the I-shaped pushing frame is fixedly connected to a positioning plate rotatably sleeved on the outside of the central axis, the front end of the central axis and the front side of the positioning plate are rotatably connected to a rotating plate, and the rotating plate and both sides of the positioning plate are fixedly connected by pins.

[0018] Preferably, one end of the front side of the rotating plate is rotatably connected to a driven shaft, and the front and rear ends of the driven shaft are respectively fixedly connected to a rotating wheel and a gear, and a plurality of paddles are equidistantly fixedly connected to the surface of the rotating wheel, and the rotating wheel and the paddles extend to the inside of the drainage trough.

Finally, multiple equally spaced areas are selected for small-scale blasting. Deep soil and rock samples are analyzed to determine metal content, and the areas with the highest and lowest metal content are identified to determine the mining plan.

[0030] Step 2: Blasting and drilling: In the selected area with high mineral reserves, use the method of fixed-point and quantitative blasting to blast the surface rock layer, then clean up the gravel, drill the rock in a small area in the blasting gap, and dig out the prototype of the mine;
