Chapter 646 The lion opens its mouth

Recovery rate refers to the percentage of the actual amount of mined ore and the designed amount of ore. The size of this number is inversely proportional to the loss in mining. That is to say, the smaller the recovery rate number, the greater the loss in the mining process.

A recovery rate of 90% means that for every 90 tons of minerals collected, 10 tons are lost. A recovery rate of 50% means that 50 tons are produced and 50 tons are wasted. A recovery rate of 10% means that 10 tons are produced.

Minerals, 90 tons will be thrown underground.

There are two main categories of losses in the mining process, one is production loss and the other is design loss.

Take coal mining as an example. During the coal mining process, even in open-pit coal mines, some waste rock will inevitably be mixed in. The possibility of waste rock being mixed in the mine is even greater, which will cause production losses.

In addition, during the coal mining process, there will be a lot of coal that has not been collapsed by the mining equipment, as well as spillage losses during transportation, etc. These are unavoidable and are also production losses.

Design losses, including in the mine design, must leave certain security pillars to ensure that the mine will not collapse. Naturally, these pillars cannot be collected.

In addition, some coal seams are not suitable for mining to avoid accidents such as water penetration, which is also a design loss of the coal mine.

These mining losses are reflected in the recovery rate.

Open-pit mining is the most cost-effective, not only because the construction difficulty of open-pit mining is low, but also because the recovery rate of open-pit mining is high. Under normal circumstances, the recovery rate of open-pit mining is above 95%. That is to say, it is a waste of coal reserves.

will exceed 5%.

The recovery rate of underground coal is definitely much lower.

European coal mining technology is developed, so the recovery rate of low coal mines is between 75% and 80%.

The United States and Australia are dominated by open-pit coal mines, with a small proportion of underground coal mines, and the technologies used are all European.

The recovery rate of China's state-owned large-scale coal mines can also reach 75%. Compared with European and American countries, it may be slightly worse, but the level is also very close.

Because large state-owned coal mines have funds to purchase equipment and enough technical talents.

When China was still a net exporter of coal, exporting coal was an important source of foreign exchange. Those who could export coal were naturally large state-owned coal companies, so they would have a certain amount of foreign exchange to purchase more advanced mining equipment from abroad.

.

As for talents, at that time, those large state-owned coal mines had sufficient resources for their own coal mining colleges, and the country's various mining universities also continuously provided talents for the large state-owned coal mines.

Therefore, only state-owned large-scale coal mines can have mining efficiency that is not inferior to that of developed countries in Europe and the United States. It is also for this reason that when coal mine prices fall, other coal mines are operating at a loss, while state-owned large-scale coal mines are still doing well.

Other coal mines do not have the technology and talent of large state-owned coal mines. Small coal mines are not willing to spend money to buy coal mining machinery or hire technicians. Naturally, the efficiency of coal mining is very poor.

The smaller the coal mine, the worse the coal mining technology. Many small coal mines owned by village collectives still use primitive manual coal mining.

Manual coal mining is inefficient and the recovery rate is also very low. The recovery rate of small coal mines run by villages or contracted by individuals is only 10% to 15%. That is to say, for every 10 to 15 tons of coal mined,

85 to 90 tons of coal were dumped underground.

In fact, most small coal mines are located in coal seams that are not suitable for mining at all. If they are forced to mine, they can only collect one ton and throw away nine tons. This will not only produce a lot of waste, but also destroy the entire area.

ecological resources.

That's why the state took action and closed down all small coal mines.

The mining area where Li Weidong is now located is barely medium-sized in scale, but it was originally a coal mine contracted by an individual. Neither the equipment nor the technology are good, and the recovery rate is only 20% to 25%.

This means that if you mine 20 to 25 tons of coal, you will waste 75 to 80 tons of coal. If you calculate it this way, you are really throwing away money every second.

Li Weidong made an estimate in his mind. With the size of this coal mine, if investment is made in equipment and technology, the recovery rate can reach 60% to 70%. This means that the coal production can be tripled!

This is all money!

Thinking of this, Li Weidong said, "We have to find a way to increase the recovery rate. The equipment can be improved, right?"

Lao Zhang nodded immediately: "The equipment used in the mine now is the updated equipment when I was the contractor."

"When you contracted the contract, it was only seven or eight years ago, right? The equipment can't be obsolete so quickly, right? You can still drive a car for more than ten years after buying it!" Zhao Jinshan said.

Lao Zhang smiled sheepishly: "Mr. Zhao, when I bought equipment, I actually bought equipment that had been eliminated from other mines."

"Second-hand equipment! No wonder." Zhao Jinshan suddenly understood and nodded.

But Lao Zhang stretched out four fingers: "When it arrives at my place, it is already a four-hand device."

Zhao Jinshan suddenly had a speechless expression on his face.

Li Weidong said with a smile; "Four-hand equipment is always much better than manual mining."

"Yes, that's what I thought at the time," Lao Zhang answered honestly.

"It seems that we have to replace a batch of new equipment." Zhao Jinshan sighed helplessly, and then said: "In a coal mine like ours, it will cost a lot of money to replace the equipment. It seems that all the profits this year will be invested again.

Already."

"Without investment, there is no profit! Furthermore, new equipment can improve the efficiency of coal production, and we will make more money." Li Weidong paused, and then said: "In addition to the new equipment, the last

It would be nice to recruit some technical talents to lay out and design the mine."

In order to improve the recovery rate of coal, in addition to using advanced equipment, technological improvement is also the main means.

The most direct way is to optimize the layout in the mine, such as the layout of the transport tunnel, the layout of the return air tunnel, the layout of the permanent coal pillars, etc. A more reasonable layout can reduce the occupied recoverable reserves, and naturally it can

Increase recovery rate.

In addition, the size design is also very important. By increasing the geometric size of the working surface, more coal can naturally be mined. Sometimes you can save a coal pillar and you can dig out a large area of ​​coal.

.

The situation in every coal mine is the same. Different coal seam thicknesses and different geological conditions must be different in layout and design. These are technical issues that ordinary coal miners must not understand and require professional expertise.

Technicians do the work.

Moreover, underground operations also involve many safety issues. How to achieve a maximum balance between safety and profit is a test for technical personnel.

However, this kind of technical personnel must be concentrated in large state-owned coal mines. How can there be any decent technical personnel in ordinary small coal mines!

Therefore, small coal mines can only mine blindly, without planning, without exploration, and without overall design. They basically dig wherever they go, and dig wherever it is easier to dig, which can easily cause safety accidents.

When Li Weidong talked about recruiting technical personnel, Lao Zhang suddenly had a look of embarrassment on his face.

"What, is this difficult?" Li Weidong asked.

"It's a bit difficult. It's easy to find coal diggers, but it's hard to find professional technicians!" Lao Kai opened his mouth and said.

Zhao Jinshan snorted coldly: "If I give you money, are you afraid that you won't be able to recruit people?"

"The main reason is that technical personnel in this field are concentrated in large state-owned coal mines. People in small mines like ours may not be willing to come!" Lao Kai opened his mouth and said.

"Then spend more money. Even technicians in large state-owned coal mines want a better life, and some of them definitely want to make more money." Zhao Jinshan said.

Lao Zhang replied: "Mr. Zhao, if you hire someone specifically, it will cost a lot of money. Given the size of our mine, the gains outweigh the losses."

Zhao Jinshan was slightly startled. Judging from Lao Zhang's answer, it seemed that things were not as simple as he thought.

Li Weidong next to him already understood what Lao Zhang meant, and he explained: "General coal technicians can be hired by spending a little more money, but when it comes to mine design, a more professional team is needed.

The mine design plan involves many technologies and parameters. Each parameter will have an impact on the future construction of the mine and the coal production and tea production work. Moreover, during the construction and mining process, the design may be changed at any time due to geological problems.

This type of talent either teaches in universities or does research in design institutes. In addition, they are teams trained by large coal companies themselves. It takes at least a dozen years to train a team like this, or even several years at most.

Ten years is the lifeblood of the enterprise, and we may not be able to dig it out."

Zhao Jinshan pondered for a moment and then asked: "We in Dongshan Mining also have many mines, as well as the two large mines of Taifeng and Taisheng. Shouldn't we also have such a team?"

Li Weidong nodded: "Of course we need a mine design team, but cultivating such a team requires time and talent.

Time can only accumulate slowly. As for talents, graduates from domestic mining universities should give priority to large state-owned coal mines. Private coal mines like ours will probably have to find others to pick the rest."

"What if we invite some retired engineers from large state-owned coal mines? This should be easier!" Zhao Jinshan said.

Li Weidong thought for a while and replied: "This is a good idea. As employees of coal companies, gay men can apply for retirement at the age of 55. This age is still considered the prime of life. If you are in good health, you will have no problem working for another ten years."

"Okay, I'll go and find out if there are any experts in this field. Let's give some more money and try to find a few." Zhao Jinshan replied.

…

At the beginning of the 21st century, what China lacks most is high-end talents.

Since the reform and opening up, many international students have gone abroad, but most of them have stayed abroad. At that time, "returnees" were still rare animals.

The reason why many people become "returnees" is either to return to China to start a business, or to return to China as senior executives of foreign companies in China.

Therefore, it is not easy for private enterprises to recruit high-end talents. Companies like Huawei, which began recruiting highly educated talents on a large scale in the 1990s, were even rarer at that time.

In addition to entering the system, most of the highly educated talents who graduated from domestic colleges and universities are absorbed by foreign-funded enterprises or state-owned enterprises.

At that time, foreign investors had good benefits and high remuneration, and it was said that Gobel had a good reputation, so they were naturally the first choice for highly educated talents. State-owned enterprises also had good welfare benefits, and they were more stable, and they were also very popular with highly educated talents.

As for private enterprises, it is difficult for highly educated talents to join unless they are offered several times the salary.

Especially in the coal industry, which is a traditional industry, professional talents are basically monopolized by state-owned coal companies.

All large state-owned coal mines have special coal schools, and the technicians they train will be given priority to their own coal mines.

Various mining universities are also inseparable from major state-owned coal enterprises. For example, China University of Mining and Technology was originally under the jurisdiction of the Ministry of Coal Industry. Later, the Ministry of Coal Industry was abolished and was placed under the management of the Coal Industry Bureau.

The major state-owned coal companies are also managed by the Coal Industry Bureau, so graduates from the Mining University must be given priority in the selection of the large state-owned coal companies. Among them, outstanding talents have already been booked by those big companies before they graduate. Where can I get them?

It is the turn of private enterprises.

This monopoly of talent is the most troublesome.

So based on Zhao Jinshan's personal connections, he searched for more than a month, but failed to find the right talent.

Many of the professors at universities or researchers at coal design institutes are experts in the industry. It's OK to ask them to provide technical support occasionally, but they are not willing to work in private companies for a long time.

As for the technical team of the state-owned coal enterprise, even if Zhao Jinshan wanted to recruit people, it would be inconvenient for him to do so. What's more, for those who have worked in the state-owned enterprise for a long time, basically their whole family is there, and their interpersonal relationships are also there, so it may not be possible to recruit them.

Willing to change jobs.

…

At the dinner, Zhao Jinshan's face looked very gloomy. He picked up the wine glass, took a sip of the wine, and then said: "Brother Li, I'm afraid the thing about the technical team you mentioned last time is going to be ruined!"

Li Weidong opened his eyes in surprise: "Can't you even find the right person? That means there are really no talents in this field in the country."

"Actually, there are still some, but the price charged by the other party is too high." Zhao Jinshan sighed, and then said: "There is Huiyuan Industrial Investment Group, and they have a professional team there who are willing to let us use it, and they are also willing to provide

Other technical support.”

"Huiyuan Industrial?" Li Weidong was surprised. In his impression, this was a large group that would rank among the top 150 among the top 500 Chinese companies in the future.

Seeing Zhao Jinshan sighing, Li Weidong asked: "Then their conditions should not be low, right?"

Zhao Jinshan nodded: "Huiyuan Industrial wants 30% of our shares!"

Li Weidong frowned slightly: "30% of the shares are really a big deal!"
