The original shaft of the Longtoushan state-owned gold mine has been blown up and sealed, and the equipment and machinery have been dismantled. But there's still a lot left over from this mine.

The factory building cannot be demolished and there is no need to demolish it, and no one takes care of it, it is already dilapidated. The walls made of red bricks are mottled and messy, weeds have grown on the walls, the red tiles of the roof are broken, collapsed, and not intact, the iron corrugated bars on the windows have long been dismantled and sold for scrap metal, and the wooden window lattices are also completely damaged.

The track trail at the exit of the mine is still there, stretching all the way out, and below the track is a dump of waste ore that is constantly piling up.

The mine was excavated in the open pit for a while, and only later was excavated into an underground mine, so that a large area of the mine was excavated after the excavation was completed. The area of exposed rock formations in the entire mountain is very large, and when viewed from the side of the national highway, it accounts for almost half of it. Due to the relatively long storage of this mine, many flowers and thorns naturally grow between the cracks of these exposed rocks, and the spots are not connected.

The construction face of this part of the original mine site is the main ecological restoration target. These areas have been excavated by man, and the rock formations have been loosened after blasting operations. Over the years, there has been a collapse phenomenon when it rains heavily, and the collapsed soil and rocks are more loose, and if they accumulate to a certain extent, when the rainfall is extraordinary, there is a possibility that mudslides may cause great damage to the national highway and villages at the foot of the mountain. Therefore, it is necessary to drive piles and build cement slope protection in these blocks to prevent such incidents from occurring.

Generally, the site is leveled first. This leveling is not to make it as flat as the airport, but to try to clean up the pumice stones, the so-called pumice stones are protruding stones, half suspended in the air, want to fall without falling, do not know when it will fall; Fill in potholes, these natural or man-made low-lying places are easy to accumulate water, soak the surrounding soil, and accelerate the weathering and corrosion of rocks, so try to fill them up.

Next, the anchor pile is fixed in the key area, and the stone is built, and then the steel wire mesh and concrete are poured to reinforce the slope that is easy to collapse.

For such abandoned mines, which are dominated by rocks, the natural growth of plants is very slow and the root system is not deep, and they may be destroyed in case of wind and rain, so these rocky beaches should be covered with soil. Trees and flowers are then planted on top of this cover to keep it from being washed away by rain.

At the same time, it is necessary to dredge the original stream ditch or manually excavate the ditch according to the topography, and do a good job in the construction of the drainage system to make the rainwater drain smoothly.

This set of procedures is very different from Cao Zhengyang's original understanding, in fact, planting trees is only the last step of the work, and he only understood it somewhat after listening to He Gong's introduction. However, he has not changed his original plan significantly, but the investment is certainly much larger than expected. To his advantage, there was also a lot of earthmoving during the construction process, which could be a good disguise for his planned mining transportation.

There is a supporting concentrator at the foot of Longtou Mountain, where the mine is located, which was also abandoned when the mine was closed, leaving behind several dilapidated machine buildings and a large tailings cofferdam. Cao Zhengyang himself doesn't care too much about this thing, although there is actually a certain amount of content in the tailings, but the current technology has no extraction value, just a pile of waste residue.

But when he first encouraged people to respond to the problem, the biggest complaint from nearby villagers was the tailings cofferdam. These slags contain a large amount of beneficiation agents added during the beneficiation, which has seeped into the soil, and the villages connected with the underground water veins here, the well water has a strange smell, and no one dares to drink it, so they have to go to other villages to get water. Even so, there are significantly more cancer patients in the village than in the past.

In addition, when it rains, the rainwater overflows from the cofferdam and floods the fields downstream with slag, and many fields are already uncultivated and abandoned.

This time, when I heard that some leaders had come to inspect the abandoned mining area, some villagers from the surrounding area organized cancer patients and elderly women to come and report the situation.

"I can't drink water, I can't plant the ground, everyone has cancer, and if this continues, the ancestral hall will be destroyed! Leader, you must make the decision for us! A thin old man came to complain, followed by a group of old men and women in shabby clothes, all of them with sleek faces and no looks, and a few of them had abscesses on their bodies, which made people dare not look at them directly.

Ren Feng also saw this kind of scene for the first time. To be honest, this place was very close to Renjiazhuang, but he never expected this to be the case. Usually there is a cancer patient in a village, and no one cares too much, and the most familiar people feel sorry for him and sigh at the impermanence of fate. Gathering so many cancer patients together and mixing them with a group of elderly women is a huge number, which is shocking!

The deputy director of the Land Bureau who led the team reluctantly stepped forward and shouted: "Folks, this mine is a problem left over from history, which has caused personal and property losses to the villagers, and our work is not good enough, I hope the villagers will understand!" Today, we are here to solve this historical problem and return the villagers to a green mountain and clear water! Please rest assured, we will definitely take this matter as a major and important thing to do, pay close attention to the implementation, and complete it as soon as possible, with quality and quantity! ”

Cao Zhengyang also showed a thoughtful expression, not knowing what he was thinking in his heart.

Fang Xiao was a little moved, his eyes were red, perhaps because he felt sad about what happened to these villagers.

Professor Shen was also silent.

The other engineers seemed a little numb and didn't look much at it, perhaps this was not the first time they had seen such a thing.

Ren Feng noticed that Zhang Zhepeng was pestering Zhang Yuerong at this time, with a seven-point contrived evil smile on his face and a natural arrogance. And Zhang Yuerong was obviously a little disgusted by this, but she couldn't get rid of it, her face was embarrassed and embarrassed, and she looked at Cao Zhengyang and Ren Feng from time to time.

Ren Feng shook his head secretly, and couldn't help but sigh in his heart. He glanced at Zhang Yuerong, stood up to help the elderly among the villagers, chatted with them by the way, asked them about their situation, and explained to them the purpose of the trip.

Zhang Yuerong immediately comprehended, and hurriedly ran over a few steps to learn from Ren Feng to talk to the villagers. Seeing this, others also had a few examples, talked to the villagers, and brought these villagers to the village by the way.

When the deputy chief saw the villagers being taken away by them, he let out a long breath.

Zhang Zhepeng looked at the backs of Ren Feng and Zhang Yuerong, revealing a contemptuous smile.

Several engineers and technicians were busy measuring dimensions, drawing records, and busy.

Noon is customary as a banquet time, and Ren Feng didn't want to go because of something, but he had to go because of his feelings.

At the main table, of course, are the leaders of the Land Bureau plus the leaders of each bidding unit, such as Cao Zhengyang and Zhang Zhepeng, who are naturally at this table. Ren Feng wanted to sit at a table with the employees of Luyuan Company, but was named by the deputy director of the Land Bureau and sat at the main table. In fact, there are only three tables in total.

After the food was served, it was naturally the deputy director who gave a speech first, and everyone toasted together. After eating for a while, it was time for personal freedom.

Although Ren Feng has also been a small boss for more than two years, he really hasn't had much contact with this kind of occasion, and he is quite restrained, so he toasted a glass of wine with everyone at the table following Cao Zhengyang's example. After that, I buried my head in eating, and when someone toasted, I was happy to dry it out, and I was happy when no one toasted.

After a few laps, some people got down to the other tables to toast.

Zhang Zhepeng toasted at the table of Luyuan Company, and first toasted a table of people. After everyone finished drinking, they began to salute the "beauties here" alone. Obviously, he came to Zhang Yuerong, Zhang Yuerong herself has no social experience, and on this occasion, she shirked a few words, but still drank a few big sips of liquor. Immediately, his face was red, like a ripe apple, and when he saw this posture, the amount of wine was very average.

Zhang Zhepeng had to have another half a cup with her, someone coaxed, and there was more than one beauty on the table, so she couldn't favor one over the other. I don't know if this heckler is bored or deliberate, the other beauty can only be Fang Xiao, because there are these two girls at this table.

Zhang Zhepeng shouted: "Where? After looking around, I saw Fang Xiao, I didn't care about it at first, and said, "Oh, I drank too much, and I actually neglected this beauty!" Penalties! ”

After speaking, he raised his wine glass to salute Fang Xiao, and looked at it again, but he didn't feel a tremor in his heart, he was really blind just now, this is definitely a big beauty, but she is too ordinary and too low-key, not eye-catching. Now my heart is even more unsettled, how can Lao Cao have such beauties here? Another persuasion to the two girls, the language began to be a little meaty.

When Cao Zhengyang saw this situation, he had to prepare to come to relieve the siege in person, but saw that Ren Feng had already come over with a wine glass.

Ren Feng first saluted the entire table, and then raised his glass to Zhang Zhepeng and said: "Zhang Gongzi, when we met for the first time, I didn't drink enough with Zhang Gongzi just now, now I must toast a few more glasses, please take care of me!" ”

Zhang Zhepeng was holding back the fire in his heart, and he didn't let people in his mouth, and squinted at the corners of his eyes and said, "How to respect the law?" Lao Cao came over, and there was a saying, how can you drink with me as a vice president? ”

Ren Feng was not angry, and said: "It's okay to compare Zhang's salary like this, you are always the deputy, in this way, I will toast you a cup, and you drink half of it!" ”

Zhang Zhepeng snorted and laughed twice: "That's it, I'll have three cups for you!" ”

Ren Feng didn't talk much nonsense: "Okay! I'll do it first! After speaking, he took a sip of a glass and toasted three glasses in a row.

Zhang Zhepeng also toasted.

Ren Feng poured wine and toasted again, in one go, even three glasses, without a break in the middle. Zhang Zhepeng had to kill a cup.

In this way, in the fourth round, Zhang Yuerong and Fang Xiao were both standing nervously, their hearts fluttering, and they almost went up to win Ren Feng's cup. And Zhang Zhepeng finally withered first, didn't drink the fourth cup, and said: "If you want to drink, you will drink with Mr. Cao!" "Staggered back to his seat.

Ren Feng smiled slightly and walked back to his seat steadily. Zhang Yuerong and Fang Xiao breathed a sigh of relief.

Of course, you can't drive after drinking, and the hotel has a special substitute driver to help them drive them back. Cao Zhengyang also drank a lot of wine, so he had to go back and have a good rest. The specific ideas of the ecological restoration project need to be discussed in another time.
