Beijing iron ore Museum

Beijing iron ore Museum

Beijing iron ore museum is located in Shouyun Iron Mine in Miyun mountain area. It is reconstructed from the building of mining area in 1960s. Due to its strong geographical location and professionalism, ordinary people seldom know about it. The museum shows the development process of mining exploration and mining technology at home and abroad, and preaches the popular science knowledge of iron ore and ore.

Development history

Standing on the viewing platform 180 meters above sea level in the mining area of Shouyun iron mine, overlooking the huge and deep bottom of the mine, Li Jingshun, director and Secretary of the Party committee of Shouyun Iron Mine in Beijing, said with pride: "in 35 years, we have dug 238 meters."

Why do you say that? He pointed to the mountain not far away and told reporters that it was the starting point when the mine was built in 1959, with an altitude of 246.8 meters. From 1959 to 1971, there was almost no ore production. In 1972, ore production began to stabilize. In 1982, the annual output of iron ore reached 6.7 million tons. In the late 1980s, the annual output reached 1 million tons. In the early 1990s, it was in a state of semi shutdown. In 2003, the annual output returned to 1 million tons and reached 1.3 million tons in 2002. "The current elevation of the mine floor is 8 meters. Starting from 1971, the cumulative output in 35 years is 23 million tons. "

Since Shouyun iron mine was put under the management of Miyun District in 2003, the mine no longer only focuses on mining, but takes the long-term route of comprehensive management and potential exploration. Shouyun people surrounded the mining area with green trees and grassland, introduced the surrounding rivers, planned to build a water leisure area, hoping to turn the mine into an industrial tourist attraction.

The mountains are green, the water is clear, and the environment of Shouyun iron mine has undergone earth shaking changes. In 2005, shouyunren began to create an iron ore Museum. In order to increase the cultural heritage, they also set up rock climbing projects and expansion projects around the museum, and built new cultural squares such as gardens, fountains and sports grounds. In the next step, the enterprise will further manage the production area, and strive to open up to the tourists who come to visit as soon as possible.

Phantom imaging

In the dark cave, two workers carrying miner's lamp and iron pick slowly move forward. The ore under their feet comes loose "Hua Hua" from time to time. After a while, they began to work. Hitting the wall of the mountain with an iron pick seems to be a small hole.

Then another worker came with a bundle of things. He carefully looked at the hole, then put a piece of solid into it, put a piece of connected rope along the mountain, and lit the rope with a match. With a loud bang, a lot of broken stones were blown down on the mountain wall. At the beginning, two workers with pickaxes came over with baskets on their backs, collected the broken stones, put them into baskets, and slowly carried them out.

This is a phantom image of the exploration and development area in the third part. The cave in the image is made of stone background, and all the characters and scenes are projected onto the glass screen by means of film and video, which is true or false. This video shows the earliest mining process. Through manual drilling and explosives, pieces of ore come out of the mountain and flow into the blast furnace to become steel.

Motion picture

Ore and explosive are a pair of difficult brothers with complex relationship. Where there is ore, there is explosive. With the roar of the explosion, the explosive disappeared, and the ore was crushed to pieces.

In the dynamic cinema, the reporter once again experienced the power of explosives. In the movie "the life of iron ore", the audience's eyes always follow a piece of ore, which enters the atmosphere from outer space and falls to the surface to form iron ore. With the explosion of explosives, it seemed to jump out of the stone like the monkey king, all the way by train, into the workshop. The reporter's seat also jumps with the bumpy wheels. After entering the workshop, it is the rolling of iron teeth and copper teeth, and the "warm" care of the high-temperature stove. Our hero's body is getting thinner and thinner. After more than a dozen dazzling processes, it changed from a big one to a small one, then to a powder, and finally to an oxide ball. Then it got on the train to the iron and steel plant and became a steel.

The roaring speakers, the swinging seats and the colorful pictures make the whole process vivid and clear. Sound, light and electricity are perfectly combined here.

Physical model

What kind of ore can magnetic levitation globe extract steel? Enter the second part of the iron ore exhibition area, the audience can find the answer.

Stepping into the exhibition hall, the first thing you can see is a big blue ball with a diameter of more than one meter spinning slowly in the air. It is densely covered with red lights, flashing. "This is the distribution of iron ore on our planet. Iron ore on the earth is mainly concentrated in Europe and the United States, while Asia and Africa are relatively poor areas. " Tang Xinmei said.

On the left side of the maglev globe, there are five pieces of ore, which are similar in rough view but different in detail. "These are the five natural types of iron ore: magnetite, hematite, pyrite, limonite and siderite. They have their own characteristics, such as magnetite is a certain magnetic, pyrite is containing a certain amount of sulfur. Shouyun iron ore is mainly magnetite. " Tang Xinmei said.

On the right side of the maglev globe, there is a natural ore of Shouyun iron mine, which is marked with different colors. According to reports, the red line represents the composition of quartz, the blue line represents the composition of iron, and the green line represents the potassium feldspar. Through this intuitive way, the audience can easily understand the various components in a piece of ore.

Inductive model recovery refining process

Through a time-space tunnel of iron tools, the reporter suddenly walked into the real world from the virtual space. Four clay miners are looking for their target iron ore with various tools.

Just a few steps forward, more than a dozen models of the same scale are lined up, as if waiting for everyone's arrival. "If you want to know how many processes it takes to turn a piece of ore into iron ore powder, you can count how many machines there are." Tang Xinmei sold a pass.

At the top of the list is a big guy, whose name plate says: jaw crusher. It turns out that the ore has to go through its iron teeth and copper teeth before it becomes small. With a slight wave of the hand on a button, the machine began to rotate, giving off bursts of roar, as if to say: "look at my ability." Needless to say, it's remote sensing.

The second is a wet autogenous mill, through the action of water, the small ore becomes finer and becomes pulp. Then, it is transported to ctb-1024 permanent magnetic separator (commonly known as coarse magnetic separator) through the conduit, and the tailings and iron ore are separated by the adsorption of a large amount of iron ore. Then, the pulp is finely screened by high-frequency vibrator in turn; the fine screened pulp is cleaned by ctb-718 permanent magnetic separator (commonly known as fine magnetic separator); finally, it is dried by ceramic filter and becomes mineral powder. All processes are clear at a glance.

The reporter also found that the step on one side is transparent glass, and there are various finished products, large ore, small ore, iron ore powder and oxide ball (the ball formed by burning iron ore powder) under it according to different processes. "In fact, all the processes are to make the ore finer. It's very convenient for the ore to be refined in the iron and steel plant after it becomes powder." Tang Xinmei said.

Physical display

In the exploration area, there are displayed the tools often used in mines in the past: hand telephone, black and white TV, balance, type printer, manual printer, 1986 four-way typewriter, and even an antique 286 computer. "This computer was the latest weapon at that time." Tang Xinmei is joking.

In the glass window on one side, there are drill rods, hammers, y24 hand-held rock drill, drill bits and impactors for kq150 down the hole drill, and three sets of work clothes of different periods. Most of the tools are rusty, lying there quietly, telling the history of Shouyun Iron Mine for nearly half a century.

"These are tools used in mines in the past. Dark blue overalls were worn in the 1960s and 1970s, light brown overalls were worn from 1983 to 2004, and dark gray overalls were worn since 2004. Many veteran comrades are very excited to see these." Facing the reporter's question, Tang Xinmei explained exactly.

On the grass outside the museum, the reporter also saw a Dongfanghong bulldozer put into use in 1969, and an iron ore transport locomotive with three buckets. Each bucket can only hold 2.5 cubic meters of ore. Shouyun iron mine used to transport millions of tons of iron ore every year little by little. Although it has retired now, it can still be seen that the output of that year Style.

Fun games

Self prospecting is like a devil stealing a mine. A mop like metal rod is connected with a disc in front of it, making sounds from time to time. This is a metal detector. In a rugged ore ground, holding this "mop", can not let the disc too far from the ground, the reporter had to bow, carefully forward. "It's like the devils in landmine war steal mines." Said the companion jokingly. "Diddidi" a burst of alarm, found the target. It turned out that the instrument found the buried iron ore. "How sensitive." Everyone sighed. It turns out that this is the "self prospecting" game in the interesting mining area. The audience can imitate geologists to find buried "treasure" by themselves. "When the May Day Museum opened for trial operation, many people were surprised
