Rebirth of the Industrial Tycoon - Vol 2 Chapter 646
Chapter 646 The Lion’s Big Opening
The recovery rate refers to the percentage of the actual mined ore volume and the designed ore volume. 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.
The recovery rate is 90%, which means that for every 90 tons of minerals collected, 10 tons are lost. If the recovery rate is 50%, 50 tons will be produced and 50 tons will be wasted, and if the recovery rate is 10%, it means that if 10 tons of minerals are produced, 90 tons will be thrown into the well.
There are two main types of losses in the mining process, one is production loss and the other is design loss.
Take coal mining as an example. In the process of coal mining, even in open pit coal mines, some waste rock will inevitably be mixed in. The possibility of mixing waste rock in the mine is even greater, which will cause production losses.
In addition, in the process of coal mining, there will be a lot of coal that has not been collapsed by 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 coal mines.
These mining losses are reflected in the recovery rate.
Open-pit mining is the most cost-effective, not only because of the low construction difficulty of open-pit mining, but also because of the high recovery rate of open-pit mining. Under normal circumstances, the recovery rate of open-pit mining is above 95%. That is, the waste of coal reserves will not exceed 5%.
And the recovery rate of underground coal is definitely much lower.
The 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 mainly open-pit coal mines, and the proportion of underground coal mines is not high, and all use European technologies.
The recovery rate of large state-owned coal mines in China can also reach the level of 75%, which may be slightly worse than that of European and American countries, but the level is also very close.
Because large state-owned coal mines have the funds to purchase equipment, they also have enough technical talents.
When China was still a net exporter of coal, exporting coal was an important source of foreign exchange, and those who could export coal were naturally large state-owned coal enterprises, so they would have a certain amount of foreign exchange to purchase more advanced mining equipment abroad. .
As for talents, those large state-owned coal mines at that time were all enough for their own coal mining colleges, and the various mining universities in the country also continuously provided talents for large state-owned coal mines.
Therefore, large state-owned coal mines can have mining efficiency that is not inferior to that of developed countries in Europe and the United States. This is also the reason. When the price of coal mines falls, other coal mines are operating at a loss, while the days of large state-owned coal mines are passable.
Other coal mines do not have the technology and talents of large state-owned coal mines. Small coal mines are reluctant to spend money on coal mining machinery, and they are not willing to spend money on technical personnel. Naturally, the efficiency of coal mining is very poor.
The smaller the coal mine, the worse the coal mining technology. Many small coal mines in villages and collectives still use primitive artificial coal mining.
The efficiency of manual coal mining is low, and the recovery rate is also very low. For small coal mines run by villages or privately contracted, the recovery rate is only 10% to 15%. 85 to 90 tons of coal have to be thrown down the well.
In fact, most small coal mines are located in coal seams that are not suitable for mining at all. If mining is forced, only one ton can be collected and nine tons are lost, which will not only generate a lot of waste, but also destroy the entire area. ecological resources.
That’s why the state took action and shut down all the small coal mines.
The mining area where Li Weidong is currently located, although the scale is barely large enough to be medium-sized, was originally a coal mine contracted by individuals, no matter whether it is equipment or technology, and the recovery rate is only 20% to 25%.
This also means that if you mine 20 to 25 tons of coal, you will waste 75 to 80 tons of coal. If you count it like this, you are really throwing money every second.
Li Weidong estimated in his heart that with the scale of this coal mine, if the equipment and technology are invested, the recovery rate of 60% to 70% can be achieved. This also means that the coal production can be tripled!
These are all money!
Thinking of this, Li Weidong said: “We have to find a way to increase the recovery rate. Should the equipment be further strengthened?”
Old Zhang nodded immediately: “The equipment used in the mine now is the updated equipment when I contracted it before.”
“When you contracted, that was seven or eight years, right? It’s impossible for the equipment to age and become outdated so quickly? You can still drive a car for more than ten years!” Zhao Jinshan said.
Lao Zhang smiled embarrassedly: “Mr. Zhao, when I bought equipment, I actually bought equipment that was eliminated from other mines.”
“Second-hand equipment! No wonder.” Zhao Jinshan nodded suddenly.
Old Zhang stretched out four fingers: “When you come to me, it’s already a four-handed device.”
Zhao Jinshan suddenly had a speechless expression.
Li Weidong said with a smile; “Four-handed equipment is always much better than manpower mining.”
“Yes, I also thought so at the time.” Lao Zhang replied honestly.
“It seems that a batch of new equipment needs to be replaced.” Zhao Jinshan sighed helplessly, and then said: “For a coal mine like ours, it will cost a lot of money to replace the equipment. It seems that this year’s profits will all be reinvested. already.”
“Without investment, there will be no profit! Besides, new equipment can improve the efficiency of coal production, and we will make more money.” Li Weidong paused, then said: “In addition to new equipment, the most important thing is It’s good to recruit some technical talents to layout and design the mine.”
In order to improve the recovery rate of coal, in addition to the use of advanced equipment, technical improvement is also the main means.
The most direct method is to optimize the layout in the mine, such as the layout of transport lanes, the layout of return air lanes, the layout of permanent coal pillars, etc. A more reasonable layout can reduce the occupied recoverable reserves, and naturally Improve recovery rate.
In addition, the size design is also very important. By increasing the geometric size of the working face, more coal can naturally be mined. Sometimes, a coal pillar can be saved, and a large piece of coal can be dug out. .
The situation of every coal mine is the same. Different thicknesses of coal seams and different geological conditions must be different in layout and design. These are all technical issues that ordinary coal miners must not understand, and require professional Technicians do the work.
In addition, underground operations also involve many safety issues. How to achieve a maximum balance between safety and profit is a test for technicians.
However, such technical personnel must be concentrated in large state-owned coal mines, and general small coal mines, how can there be any decent technical personnel!
As a result, small coal mines can only be mined blindly, without planning, exploration, or overall design. Basically, it counts where you dig, and which side is good for digging, which can easily lead to safety accidents.
Li Weidong said that he was recruiting technicians, and Lao Zhang’s face suddenly showed embarrassment.
“Why, is this difficult?” Li Weidong asked.
“It’s a bit difficult. It’s easy to find coal diggers, but professional technicians are not easy to recruit!” Lao Zhang said.
Zhao Jinshan snorted coldly: “I’m giving money, but I’m afraid I won’t be able to recruit people!”
“Mainly the technical personnel in this area are concentrated in the large state-owned coal mines. I am afraid that people are not willing to come to our small mines!” Lao Zhang said.
“Then spend more money. Even the technicians of large state-owned coal mines want to live a better life, and there must be some who want to earn more money.” Zhao Jinshan said.
Old Zhang replied: “Mr. Zhao, if you hire someone specially, you will have to spend a lot of money. With the scale of our mine, it’s a bit of a loss.”
Zhao Jinshan was stunned for a moment. Judging from Lao Zhang’s answer, it seemed that things were not as simple as he thought.
Li Weidong, who was next to , already understood what Lao Zhang meant, and he explained: “General coal technicians should be able to pay a little more money, but when it comes to mine design, a more professional team is needed.
The design of the mine involves many technologies and parameters. Each parameter will have an impact on the construction of the mine in the future and the work of producing coal and tea in the future. In the process of construction and mining, the design may be changed at any time due to geological problems.
Talents of this type either teach in universities or do research in design institutes. In addition, they are the teams cultivated by the large coal companies themselves. Cultivating a team of this kind is the lifeblood of an enterprise, and we may not be able to dig it. ”
Zhao Jinshan pondered for a moment, then asked, “We also have a lot of mines in Dongshan Mining, as well as two large mines, Taifeng and Taisheng. Shouldn’t there be a team like this?”
Li Weidong nodded: “Of course we need a mine design team, but to cultivate such a team requires time and talents.
Time can only be accumulated slowly. As for talents, graduates from domestic mining universities should give priority to large state-owned coal mines. I am afraid that private coal mines like us can only find some others to pick the rest. ”
“What if we hire some retired engineers from large state-owned coal mines? It should be easier!” Zhao Jinshan said.
Li Weidong thought for a while and replied, “That’s a good idea. A **** man in a coal company can apply for retirement at the age of 55. At this age, he is considered a prime man. If he is strong, he can work for another ten years.”
“Okay, I’m going to ask if there are experts in this field. Let’s give more money and try to find some.” Zhao Jinshan replied.
…
In the early 21st century, what China lacked most was high-end talents.
Since the reform and opening up, many international students have left the country, but most of them have stayed abroad. At that time, “returnees” were still scarce animals.
The reason why many people become “returnees” is either to return to China to start a business, or to return to China as executives of foreign companies in China.
Therefore, it is not easy for private enterprises to recruit high-end talents. Companies like Huawei that began to recruit highly educated talents on a large scale in the 1990s were even rarer at the time.
The highly educated talents who graduated from domestic colleges and universities, in addition to entering the system, are mostly absorbed by foreign-funded enterprises or state-owned enterprises.
At that time, the foreign capital had good benefits and high salary, and it was naturally the first choice for highly educated talents. The benefits of state-owned enterprises are also good, and they are more stable, and they are also very popular with highly educated talents.
As for private enterprises, unless they are given several times the salary, it is difficult for highly educated talents to join.
Especially in the coal industry, which is a traditional industry, professionals are basically monopolized by state-owned coal enterprises.
All large state-owned coal mines have special coal schools, and the trained technicians will definitely be assigned to their own coal mines first.
Various mining universities also have inseparable ties with 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 revoked and placed under the management of the Coal Industry Bureau.
The major state-owned coal enterprises are also managed by the Coal Industry Bureau, so the graduates of the University of Mining and Technology must be selected first by the large state-owned coal enterprises. Among them, outstanding talents have already been reserved by those large enterprises before they graduate. Where can they be? turn to private enterprises.
This kind of monopoly of talents is the most troublesome.
So, based on Zhao Jinshan’s personal connections, he searched for more than a month, but he couldn’t find a suitable talent.
Those professors in the university, or the researchers in the Coal Design Institute, are many experts in the industry. It’s okay to ask them to do technical support occasionally, but it’s okay to ask them to work in private enterprises for a long time, but they don’t want to do it.
As for the technical team of state-owned coal enterprises, even if Zhao Jinshan wanted to poach people, it was not convenient to do so. What’s more, those who have worked in state-owned enterprises for a long time, basically have the whole family there, and the interpersonal relationships are also there, and they may not be willing to change jobs.
…
During the dinner, Zhao Jinshan looked very gloomy. He picked up the wine glass, took a sip of the wine, and then said, “Brother Li, I’m afraid the matter of the technical team you mentioned last time is going to be yellow!”
Li Weidong’s eyes widened in surprise: “Can’t even you find a suitable person? That means that there is really no such talent in China.”
“Actually there are, but the other party’s asking price is too high.” Zhao Jinshan sighed and continued: “There is Huiyuan Industrial Investment Group, they have a professional team willing to use it for us, and they are also willing to provide other technical support.”
“Huiyuan Industry?” Li Weidong was taken aback. In his impression, this is the top 150 large group among the top 500 Chinese enterprises in the future.
Seeing Zhao Jinshan sighing and sighing, Li Weidong asked, “Then their conditions should not be low, right?”
Zhao Jinshan nodded: “Huiyuan Industry wants 30% of our shares!”
Li Weidong frowned slightly: “30% of the shares are really a lion’s mouth!”
