Recently, Bingcheng is manufacturing some large-scale communication equipment.
Some of the iron ore is transported to Ice City.
They went to check the mining conditions of the iron ore and found no problems.
This iron mine is relatively far from both the pillar mine and the coal mine.
Peng Qing said: "Should this iron mine also need to be inspected more closely?"
Pu Lei said, "Has anything unusual happened recently?"
Tao Decai said: "The abnormal situation is that there are more construction vehicles coming in and out recently."
Peng Qing said: "There are just a lot of engineering vehicles coming in and out. Vehicles entering and exiting need to be inspected. If the vehicles coming out are mining, they need to be registered."
Pu Lei said: "Then if there is nothing in the truck body, it can pass, right?"
Peng Qing said: "That's for sure. If there is nothing in the truck body, there must be no mining. That is to carry out tasks such as transporting rocks and soil inside."
Pu Lei said: "Although it is relatively far, let's go take a look."
There is a fence at the outermost level of the mine. There are some iron gates for vehicles to enter and exit, and registration is done at the iron gate.
The guard said, "What are you doing here?"
Peng Qing said: "Look at the problem of mineral loss."
The guard said: "This is mainly iron ore."
Peng Qing said: "Yes, it's iron ore."
Pu Lei didn't answer in a hurry, but he thought to himself, isn't it Zhu Mine?
The guard said, "Are you sure?"
Peng Qing said: "What do you want to say?"
The guard said: "I heard that there was a problem with the pillar mine in another mining area."
Pu Lei said: "But there is also a problem here. We need to go in and take a look. I repair equipment."
The doorman said, "Which piece of equipment has a problem?"
Pu Lei said: "Giant excavator."
The excavator is about 20 meters high, corresponding to approximately 6 floors. The machine is 10 meters wide and 30 meters long. It is equipped with 12 buckets and weighs 700 tons in total.
The doorman said: "Okay. After registering, you can go in."
Pu Lei said: "What did he mean by asking just now?"
Peng Qing said: "I think I just don't want to let him in."
Pu Lei said: "This can't be blamed on him. With these strange things happening recently, the administrator should also think that people can't just enter and exit these areas."
Peng Qing said: "You said this giant excavator was also made by our factory?"
Pu Lei said: "No, we don't have such a large manufacturing workshop, but we make some gears and bearings."
Peng Qing said: "This is really big. It's like a car, it's both a mechanical device and a large building."
Pu Lei said: "We still have to look for any clues here quickly."
Peng Qing said: "Look at what's wrong."
Pu Lei said: "It's in the open air. I can't see anything anywhere."
"Get on that giant excavator first."
They reached the control room on top of the excavator to take a look. It is surrounded by rocks and there is a large sunken pit in the middle.
Peng Qing said: "You can't really see anything here. But looking down from here, it's quite shocking. It's very beautiful."
Like giant flowers that stretch out all around, with some dark brown stamens in the middle. It also looks like the mark left by a giant hammer.
There are simple roads in a circle, and you can go around the road from the top to the bottom. You can also take the zigzag route up and down. There are some small excavators working.
They looked around and saw some small potholes. A truck came out of it. It's just that the color is different from the outside, but there's nothing inside.
Peng Qing said: "The truck transports things, and there should be some ore in the back."
Pu Lei said: "Maybe we are too far away to see clearly, so we can't hold so many."
Peng Qing said: "Let's go take a look in that pothole."
They went down the hillside. There are dirt and rocks next to it, making it difficult to walk.
When we reached the hollow, our shoes were covered with mud.
They entered along the hollow.
Pu Lei said: "You are outside now, I will go in and take a look."
He walked away for a while and then came out again.
Peng Qing said: "How deep is it inside?"
Pu Lei said: "It's dark inside, and there are only lights at long intervals."
Peng Qing said: "Is this road easy to walk?"
Pu Lei said: "It's not easy to walk. It's full of mud."
Peng Qing said: "What should we do? Can your power-assisted machine be used?"
He took off his backpack and looked through it. There is a kind of shoe with a support pole below that has a certain height. "Then I'll try wearing these shoes with high poles."
These were originally intended for jumping, increasing the height and distance of the jump.
Now it is used as stilts. The bottom of the pole has a relatively small cross-sectional area and has less contact with the soil, but it is easy to insert into the soil.
Peng Qing said: "Then if it is fixed on the top of the cave, can I go there? Is it convenient?"
The suction cup tool can indeed be fixed to the top of the hole, but the top of the hole is not very flat. The vacuum inside the suction cup needs to be increased, and it takes a bit long.
Peng Qing said: "What should we do? There is a lot of mud here and it is not easy to walk."
Pu Lei said: "How about waiting for a construction vehicle to come over and then go in."
He said hello as a construction truck passed by. "Can you take us in? Let's go in and check out the equipment inside."
"who are you?"
Pu Lei said: "We are workers at the Shengshi City Machinery Processing Factory."
"It's just for mining. Doesn't it have any of your mechanical equipment?"
Pu Lei said: "We want to go in and take a look."
"I can't take you in without permission." He drove off in the truck.
Pu Lei said: "Why don't those cars get stuck in the mud?"
Peng Qing said: "Maybe the contact surface between the wheels and the mud is relatively large."
Pu Lei said, "What will happen if the vehicle gets stuck in the mud?"
Peng Qing said: "I remember this. Find some rocks and put them around the mud, and drive the car out with the help of the rocks at full speed. Or use a jack to lift the wheels stuck in the mud pit, start the car and drive out. Or find a stick about Use a half-meter-long wooden stick and a rope about three meters long; use the rope to tie the wooden stick directly to the tire; start the car engine and control the strength of the accelerator, and the wheel will easily come off with the help of the bite force of the wooden stick."
Pu Lei said: "That is to say, the contact area must be increased so that it is not easy to get stuck in the mud."
Peng Qing said: "Look, there are some discs here. Can they be fixed at the bottom of the pole under the shoes? Then this can increase its contact area and prevent it from falling into the mud easily. And when it is pulled out, the mud will It’s not stuck on either.”
Pu Lei said: "Okay, I can only give it a try."
They each added a disc under their shoes and continued walking along the tunnel.
