Chapter 646: Gold mining

The first thing that came out was the sand, because the iron content was relatively high, with a reddish red color. After the sand was mined, it was transported away by a vehicle that had been standing by for a long time, and piled up at the tailings yard one kilometer away.
One meter, two meters, three meters...
The sand has low hardness and is still easy to dig. After about an hour, the depth of this large mine has reached several meters, and sand and gravel have begun to appear, with a little harder and harder.
Even the hard rock formation is not a problem under such a shield machine. These sands are also cut and then sent out. The large mine remains level and the depth gradually deepens.
Gold mining refining workshop.
More than a dozen workers are already on standby. As long as the gold mine is shipped over, everyone will start to refine the gold mine and separate the gold from these ores.
Most of these employees are selected from the old employees of Australia's No. 1 mine and No. 2 mine. They are very reliable. Such employees are more comfortable to use.
A few hours later.
The shield machine has been digging to a depth of at least 20 to 30 meters. Wang Xudong came here again and quietly activated the "God-level Mine Owner" system. It can be seen through the holographic three-dimensional map that the shield machine will soon dig into the gold. Mineral veins, in other words, the first batch of gold mines will soon be mined.
Wang Xudong said with joy: "I have a hunch that gold ore will come out soon."
Gail, who was next to him, was overjoyed and shouted loudly: "Guys, I've paid attention to it. It has been digging twenty or thirty meters, and there should be ore coming out soon."
He has always believed in Wang Xudong's words. A few months ago, Wang Xudong sent him here to take charge of the construction of this large gold mine. He said that there is a wealth of gold here.
Now, Wang Xudong said that a gold mine would be mined soon, and Gail was convinced that he shouted, and gazed at the front happily, watching the mined sand.
These are sandstones, which are not very hard and are relatively easy to mine among all types of gold ore. There are many types of gold ore, such as placer gold ore, gold-bearing quartz gangue, volcanic gold ore and so on.
Sandstone is divided into quartz sandstone, feldspar sandstone and lithic sandstone. Here is lithic sandstone, which is rich in gold. Such a ton of sandstone mine contains tens of grams of gold on average.
"Gold ore is out!"
There is an employee with yellow skin and black hair. He is from Huaxia. Among the employees of Dajin Mine, more than half are Huaxia and ethnic Chinese, and the rest are whites, blacks, and so on.
His name is Li Honggang. He is an old employee of the former No. 2 Iron Ore. He has mined gold in his hometown in China. He has certain experience and was selected as the monitor of a miner class.
Li Honggang was the first to discover gold ore, and immediately shouted loudly. Hearing this surprise shout, many people craned their necks.
It is indeed gold ore.
With the excavation of the shield machine, the sandstone ore containing gold finally came out. Wang Xudong was also overjoyed and walked forward, picking up one piece and looking carefully.
Obviously, the grade of this ore is not low. You can see that there are several tiny golden dots on the ore, which are tiny gold particles.
"Wang, it's really a gold mine!"
At this time, a big man like Gail also yelled with excitement. Holding a piece of ore in his hand, under the sun, there are obviously golden dots on this ore, shining.
The first gold mines were mined.
After the shield machine mined another distance, its mission was completed and it began to withdraw. After it came out, a large mine with a diameter of several meters, enough to drive into a large truck, appeared in front of everyone.
As you all know, the other side of this big mine is a gold vein. There is no need to give orders, and the on-call miners get busy immediately. The first thing is to strengthen the mine.
The four walls of the mine are sand or sand. Only a few meters at the end are sandstone. Both sand and sand are unstable. To prevent it from collapsing, it needs to be reinforced.
The method used is also very advanced. Not far away, huge cylinders are prepared. These are large concrete steel cylinders with a wall thickness of about 20 cm and a length of one meter. The diameter is only larger than this excavated mine. A little bit smaller.
Through special equipment, the first large concrete cylinder was pushed over, and carefully and slowly pushed into the mine. A middle-aged man in overalls and hard hat yelled.
"Slow down, be careful, be careful of collapses!"
This is Joseph, the chief engineer of the Big Gold Mine. He has rich experience in gold mining and is instructing everyone to use equipment to advance the first large cement cylinder.
These large cement cylinders were prepared a long time ago. According to the mining technology, the shield machine was first used for excavation. After mining to the gold mine, the shield machine withdrew, and such large cement cylinders were sent into the large mine one by one. They are put together tightly to form a cement mine.
The first large concrete cylinder was slowly and carefully sent into the big mine cave, as if it were sent into a big hole like a huge ring.
"Okay, it's in place, OK!"
Joseph gestured and shouted loudly, indicating that the first large concrete cylinder was in place, and then began to send the second one.
Seeing this method, Wang Xudong is also regarded as an eye-opener. This is not only fast, but also very safe. The important thing is that after these cylinders are fed in, a cement mine is formed, and then gold mining can be continued immediately. Do not waste time.
The first, the third, the fourth...
The following was getting smoother and smoother, and no collapse occurred. For more than two hours, all of the more than twenty cylinders were sent into the big mine and completed smoothly.
Gal said: "Wang, the mine is now very strong and safe. We can go in and take a look."
Wang Xudong had this intention, and took the miner's lamp from Gail, and was the first to walk into the mine, and Gail and others followed suit.
Walking into the big mine, Wang Xudong found that the entire mine was level and straight, and the walls were made of thick cement. The large cement cylinders were stitched together seamlessly, and there was almost no gap between them.
Walking along the mine cave, it soon came to an end, where there are a lot of sandstone rock walls, there are traces of shield tunneling on the rock walls, of course, there are also many golden dots.
Under the illumination of the miner's lamp, these golden dots looked very gratifying. Wang Xudong couldn't help reaching out his hand and touching the rock wall.
gold!
People next to Wang Xudong looked at each other excitedly when they saw these sandstones, and everyone seemed to see a lot of golden gold.
Gail promised: "Wang, don't worry, I will organize the most reliable people to mine gold. There will not be a small amount of gold flowing out, and they will all enter our vault."
Seeing this extremely high-grade gold vein, Gail knew that everything must not be sloppy, and strict management must be performed to ensure that the gold is mined in an orderly manner and not outflow.
Wang Xudong nodded and waved: "Okay, let's start gold mining. I will see our first batch of gold tomorrow."
Today is enough. The shield machine is used to dig into the front of this gold vein, and the mine has been reinforced with scientific methods. The gold mine has been able to be mined. Today's results have been very good.
The first batch of gold mines were also carefully collected, mainly mined by shield machines, weighing at least tens of tons. After being collected, they were sent to the gold refining workshop.
After Wang Xudong and others left the mine, the miners of the first group, led by the monitor Li Honggang, began to enter the mine to mine gold.
This is a typical mine method.
Naturally, there is no need for Wang Xudong to worry about the mining process, mining details, etc. There are technicians and engineers here. As the boss, just wait for the gold mine to be mined and then refined into gold.

Xudong Mining Group.
Both Liang Hongbo and Xu Jie are happy. Today is equivalent to a double happiness. A large overseas steel group sent someone to the door and signed an order for 10 million tons of iron ore with Xudong Mining Group. This is the first happiness.
If it were a month ago and faced with an order for another 10 million tons of iron ore, Liang Hongbo might hesitate to sign or not to sign.
Now he has no worries in this regard at all, because with the batch input of joint mining vehicles, the expansion of major mining areas, etc., he knows that there is no problem at all with another 10 million tons of iron ore orders.
The second good news is that the Xudong Mining Group’s aircraft has finally arrived. The Gulfstream G550 aircraft has been parked at Donghai International Airport.
Liang Hongbo said happily: "Xu Jie, our plane has arrived. Brother Dong happened to be in Australia. I heard that we are going to mine gold. Let's go and take a look at that big gold mine."
This big gold mine also belongs to the Xudong Mining Group. It will be under the jurisdiction of the two people. If you think about the big gold mine, they both want to take a look at it.
Xu Jie said: "No problem, we will leave tonight, we will be able to arrive in Australia tomorrow morning, and we will be able to reach our big gold mine in the morning."
The two quickly agreed, prepared to deal with the affairs at hand, set off in the evening and flew to Australia overnight.

Territory No. 2, a small town.
It's time to rest at night~EbookFREE.me~ Before going to bed, Wang Xudong took out his mobile phone and was watching the videos and pictures sent to him by Liao Teng.
Zheng Xiaotong also came over with great interest and looked at the things on the phone.
"Brother Dong, this is the assembly line for automobile engines. The degree of automation is really high!"
This production line was manufactured by Sunward Heavy Industry Group in accordance with the technical data in the "God-level Big Miner" system. Wang Xudong had been on vacation for the first half month. He is now in his No. 2 territory and did not go to Sunward Heavy Industries. It is also the first time to see this production line for engine assembly.
Wang Xudong said: "It's like watching a science fiction movie, too advanced!"
In addition to these pictures and videos, Liao Teng also sent a request as to whether to make such videos public.
Is it public or not?
………
The first one is sent! .
