"Why do you have to solve the gas problem in the Jiuhe Coal Mine?" Bao Feiyang asked Meng Dehai puzzled, "The profits brought by the Fangxia Kaolin Company, a joint venture between our Jiuhe Coal Mine and Fangxia Ceramic Chemical Co., Ltd., are even several times higher than the profits of our entire Mining Bureau!" ”

"Fangxia kaolin is Fangxia kaolin, and Jiuhe Coal Mine is Jiuhe Coal Mine." Meng Dehai waved his hand with a straight face, and said unreasonably: "Coal is the main business of our Mining Bureau, and no matter how much money is made from the kaolin project, it cannot replace the main business." After such a long time, the amount of coal mined in the Jiuhe Coal Mine has dropped by 80 percent compared to before you became the mine manager. ”

"Director, isn't that because of the world-wide problem of adsorption gas in the Jiuhe Coal Mine? If it is still mined as before, there must be a lot of potential safety hazards, and there may be a gas explosion at any time. Bao Feiyang said, "Although the mining volume has dropped by 80 percent, it has avoided potential safety hazards, coupled with the commissioning of the kaolin project, it is foreseeable that the total profit of Jiuhe Coal Mine throughout the year can easily exceed the sum of the other four major coal mines of our Tianyuan Mining Bureau several times!" ”

"I'm talking to you about the main business now, why do you have to get involved with me on the side business?" Meng Dehai knocked on the table, "It is precisely because of the world's problem of adsorption gas in your Jiuhe Coal Mine that I let you solve this problem before leaving?" Otherwise, wouldn't it prove that I had made a wrong decision to appoint you as the director of the Jiuhe Coal Mine? ”

"Director, I ......" Bao Feiyang still wanted to defend.

"Okay, okay, in short, in a word," Meng Dehai interrupted Bao Feiyang's words and said, "If you want to transfer away." You have to solve this problem of adsorption gas. If you don't solve it well, you will be the mine manager of Jiuhe Coal Mine for the rest of your life! ”

**************************************

Leaving Meng Dehai's office, Bao Feiyang couldn't help but snicker. I didn't expect Shang Shanluan and Meng Dehai to be so insidious, and they would use the world problem of adsorption gas as an excuse to stop him from leaving Tianyuan. Fortunately, he was prepared, otherwise he would have been stumped by Meng Dehai's request, or he would have obediently stayed in Jiuhe Coal Mine as a mine manager. Otherwise, according to what Shang Shanluan said, he was transferred to the municipal government as Zhong Yanming's secretary.

Of course, Bao Feiyang's side can also ask the Environmental Protection Department to coordinate with the Tianyuan Municipal Government through Guò Su Qingmei, or directly transfer the order, but in this way, it is inevitable that he will have an unpleasant quarrel with Zhong Yanming, Shang Shanluan and Meng Dehai. Although the intimate relationship established in the past ten months will not disappear, it will also create a large estrangement. It will never be as intimate as it is now.

Now, although Meng Dehai proposed to let him solve the world's problem of adsorption gas in Jiuhe Coal Mine before leaving, he wanted to use this impossible task to prevent Bao Feiyang from being transferred to the Provincial Environmental Protection Department, but for Bao Feiyang, it was a shortcut to leave Tianyuan City without harming his anger.

Regarding the problem of adsorption gas in Jiuhe Coal Mine, Bao Feiyang never stopped looking for a solution. Because Bao Feiyang knows. Although the coal industry has been sluggish in recent years, it will usher in a golden exhibition period in a few years, when coal will become real black gold. Bring endless riches. The coal black, who was looked down upon, will also become an enviable coal boss. Although Bao Feiyang is very disgusted with the hateful faces of the coal bosses who are waving checks everywhere after 2000 to buy gold, luxury cars and mansions, he has to admit that it is these people who are keenly aware of the huge potential of the coal industry, so as to seize the opportunity and make a big windfall after the arrival of the golden age of the coal industry. Since those coal bosses can do this, how could Bao Feiyang, a person with the memory of rebirth, give up such a great opportunity? In particular, he is now the director of a coal mine with billions of tons of coal reserves. In later generations, when coal reserves were at their highest, a ton could even be sold for more than 200 yuan, and it is not uncommon to see that the worthless Jiuhe Coal Mine will be worth hundreds of billions of yuan in the future.

It is precisely because of the understanding of the trend of the coal exhibition that Bao Feiyang has not relaxed the search for the treatment method of adsorption gas in the Jiuhe Coal Mine, and the professors and experts of several well-known mining universities and several coal research institutes in China are frequent visitors to the Jiuhe Coal Mine. At the same time, Bao Feiyang also subscribes to international scientific and technological journals, always tracking the latest developments in gas control in the international coal industry.

About two months ago, Bao Feiyang published an article in the International Energy Journal by an expert from an island nation entitled "On the Mechanism of Methane Hydrate Formation in Coal Seams".

Methane hydrate is still a very unfamiliar word for the vast majority of people in this era, but for Bao Feiyang, it is a familiar word that can almost hear the cocoon, which is quite popular and popular in modern science and technology after more than ten years, and is a new energy that can replace oil and coal at a certain point in time in the future that the scientific and energy circles have high hopes for.

In later generations, methane hydrate, also known as "combustible ice", is a cage-like crystallization formed by methane gas and water molecules, and ordinary natural gas can be obtained by separating the two. This outwardly ice-like material is formed under high pressure and low temperatures, which means that it is usually stored in the six seafloor formations and the permafrost zone at the Earth's poles.

Methane hydrate is a new type of fuel that can be used as a new energy source, which naturally attracted the attention of Bao Feiyang, although he was not involved in the energy industry in his previous life, but he still had contact with methane hydrate. It was at the Guangdong Fair held in the Special Economic Zone of Eastern Guangdong Province that Bao Feiyang accidentally met a business owner in an island country, who leaked information about methane hydrate and even brought samples over. The island country is surrounded by the sea on all sides, belongs to the defeated country in World War II, and is sparsely populated, due to the limitation of national strength, they can only open resources in the mainland, the island people are black, and do not want to exploit the limited resources in a short period of time, so the island people who are hungry for profit in this regard should take a few steps ahead of China. It's just that even in the era of more than ten years later, when the technology is much higher than now, the problem of the development and utilization of methane hydrate has not been well solved, so although the world has heard the term methane hydrate, most of them know that this is a new type of energy raw material. However, there is no deep understanding of methane hydrate, and even the islanders who have a strong sense of energy shortage crisis have not found any field where methane hydrate can be applied for the time being.

It is not surprising that Bao Feiyang has now seen this article "On the Mechanism of Methane Hydrate Formation in Coal Seams" written by experts from island countries in the international new energy magazine. It's just that what makes Bao Feiyang strange is that he originally had the impression. Methane hydrate is only stored on the ocean floor in the depths of the ocean, and in the cold and cold environment of the deep ocean, coupled with the pressure of thousands of meters of seawater, methane gas combines with water to form methane hydrate. But Bao Feiyang did not expect that among the coal seams of the coal mine. It is possible to have the conditions for the formation of methane hydrate.

So Bao Feiyang studied the island country energy expert very seriously, and this article came. The point made in this article is that there is already a real proof of this. Under certain temperature conditions, at a certain temperature, as long as the pressure is appropriate, there is a methane gas source and water, methane hydrate can be synthesized, and the storage of porous media will help the formation of hydrate.

According to the analysis of experts from the island country. Methane hydrate, which is a cage hydrate, belongs to the master-guest compound. Water molecules attract each other with hydrogen bonds to form a cage. As the main body, methane resides in the cage as an object, and the van der Waals force and water molecules attract each other to form a cage-shaped hydrate. The space of the cage must match the size of the gas molecules in order to form a stable cage-shaped hydrate. It is generally believed that the formation of methane hydrate requires three conditions: 1. The temperature should not be too high; 2. The pressure should be large enough; 3. There should be a methane gas source. And now it has been proved that at a certain temperature, as long as the pressure is right and there is a methane gas source, it is possible to synthesize methane hydrate.

Coal is a porous medium that produces large amounts of methane during its formation and contains large amounts of water. Affected by tectonic stress and in-situ stress, there are cracks, faults, etc. in the coal seam, and the structure is complex, so there is a high stress zone in the coal seam, and this high stress zone creates conditions for the storage of methane hydrate.

In this paper, the principle of methane hydrate formation in coal seam is discussed, and it is proposed that the formation of methane hydrate is formed by the electrostatic interaction between methane molecules and water molecules under a certain temperature and pressure. According to the different sources of methane hydrates, gases can be divided into two categories: one is biochemical; The other type is pyrolysis genesis. It is generally believed that methane hydrate can be formed as long as the physical and chemical conditions for methane hydrate stability are met. As a result, methane hydrates can be formed in different systems (open or closed) and in different environments (oceans or 6 places). In general, the geological models of methane hydrate formation can be summarized as follows: cryogenic freezing mode, transgression model, fault model, authigenic monogenetic model, sedimentary model, and various percolation modes (pressure infiltration mode, geothermal model, airflow model). In addition, methane hydrate formation requires sufficient interstitial water in the organic-rich sediment, which is exactly what coal seams do.

At the same time, the paper also analyzes that in some coal mine gas outburst accidents, the gas outburst per ton of coal is much higher than the gas content per ton of coal, which is unexplainable, and provides evidence for the local presence of zài methane hydrate in the coal seam. Therefore, it is inferred that there may be scattered methane hydrates in the coal seam.

After carefully studying this article, Bao Feiyang's eyes couldn't help but light up. It's not that he figured out the new energy of methane hydrate produced in the coal seam in guò, this idea is unrealistic, not to mention that the mining research of methane hydrate is not lagging behind, and there is no technology that can effectively mine methane hydrate, just in terms of the methane hydrate distribution in the coal seam is very scattered, the methane hydrate in the coal seam basically has no mining value.

But for Bao Feiyang, this provided him with an idea to solve the global problem of adsorption gas in Jiuhe Coal Mine. Since the coal seam can find the existence of methane hydrate, then that is to say, gas can be converted into methane hydrate under certain conditions, so can certain conditions be imposed to promote the transformation of gas in the coal seam into methane hydrate? What happens if the adsorbed gas is converted into methane hydrate?

So Bao Feiyang told his ideas to the experts of Huaxia University of Mining and Technology, and the experts of the University of Mining and Technology were very interested in Bao Feiyang's proposal, because they knew that methane hydrate, as a special energy substance with high-density absorption and fixation of small molecular gases such as methane, needs to absorb surrounding heat during biodecomposition. This is actually the same property that alcohol and dry ice sublimation take away the heat from the surrounding area. According to Bao Feiyang's idea, if the adsorption gas in the coal seam can be turned into methane hydrate, then in the actual coal mine mining, when the coal seam is broken, the methane decomposition in the hydrate hydrate state needs to absorb a lot of heat, and these hydrates are difficult to melt and decompose in an instant to form a gas storm when the coal is broken, so as to avoid the occurrence of coal and gas outburst accidents. Then adsorption gas, the world's big tiger in the coal mining industry, has been killed.

A strong ventilation system is easy to solve, as long as it is modified on the basis of the existing ventilation system of Jiuhe Coal Mine. The key question is how to turn the adsorbed gas from the coal seam into methane hydrate.

Therefore, according to Bao Feiyang's requirements, the expert group of the University of Mining and Technology carried out a reverse extrapolation according to the formation conditions of methane hydrate in the coal seam, and finally studied the methods of medium and high pressure water injection and surfactant added to the water, so that the adsorption gas in the coal seam of Jiuhe Coal Mine can be stored in the form of methane hydrate. This method has been successfully tested on a small scale a week ago, but it is temporarily kept secret at the request of Bao Feiyang, and will be announced when it can really be used in actual production after debugging. The most important reason why Bao Feiyang agreed to Su Qingmei to go to the Provincial Environmental Protection Department is that he has basically solved the old and difficult problem of adsorption gas in Jiuhe Coal Mine. Even if this scientific and technological achievement is placed in the world's coal mining industry, it is also a success with considerable technical content, as a coal mine manager with a silicate professional background, to be able to do such an achievement in the coal industry, even if it is modest, it can be regarded as earth-shattering.

But Bao Feiyang didn't expect that Meng Dehai would make it difficult for him to solve the problem of adsorption gas, if Meng Dehai knew the truth, would he regret going to his grandmother's house?

and Zhong Yanming and Shang Shanluan standing behind Meng Dehai, they must also regret crushing their teeth, right?

Anyway, Bao Feiyang is still very grateful to the three leaders Zhong Yanming, Shang Shanluan and Meng Dehai in his heart, it is precisely because of their appreciation of himself that he has lived such a wonderful life in Tianyuan City in the past ten months, right?
