In the mining and smelting industry, the earliest and most widely used is the coal mining industry.

China is the first country in the world to use coal as fuel. This period began in the Western Han Dynasty. Since the Song Dynasty, coal began to be used on a large scale among the people, while coke used for smelting steel appeared in the Southern Song Dynasty and later began to be used in large quantities in the Yuan Dynasty.

After the founding of the Ming Dynasty, ordinary residents generally used coal as fuel for cooking and heating, and most of these coal-producing areas were in the North.

The most famous coal production areas now include Niutoushan Coal Mine in Hanshan County, Hezhou, Baiyangkou Coal Mine in Changpingzhou, Shuntian Prefecture, Northern Zhili, Xishan Coal Mine in the capital, Pingdingzhou Coal Mine in Taiyuan Prefecture, Shanxi, and Xishan Coal Mine in the capital, which are the main fuel sources for daily life of residents in the capital.

From the experience of later generations, coal resources reserves in Shanxi, Shandong, Henan, Northeast China and other places are extremely rich. Now, due to various reasons, the coal mining industry in these provinces has not flourished, and coal mining is limited to micro-coal mines that some local major households have gathered or hired more than a dozen or twenty people to start.

Under Zhu Youjian's instruction, Sihai Coal Industry has been established and has begun to explore coal mines in the North and mine them.

Sihai Coal Industry spent a lot of money and hired many experienced old miners. These people could distinguish the appearance from the soil surface and then dig to prevent gas and poison in the mine pit. "When they first saw the coal end, the poisonous gas (gas) burned people. Some people chiseled the giant bamboo off the middle section, sharpened the end, and inserted it into the charcoal. The poisonous smoke penetrated from the bamboo. People applied it from the bottom. Or they went down a well, and the charcoal was wide and wide. Then they were taken along the left and right, and the upper plate was supported to prevent the ears from collapse."

Taking the support level of thick wood to prevent problems such as roofing is also the first in China, which is of great significance in the history of world coal mining.

Over the past three years, Sihai Coal Industry has opened coal mines and coal yards in five prefectures and counties, and the total number of workers has reached more than 300. With the continuous accumulation of various experiences, the amount of coal produced is also increasing, and the profits are also extremely considerable.

According to Zhu Youjian's instructions, Sihai Coal Industry adopted the method of hiring people with high-tech. The monthly salary collected by coal miners was quite generous, and the daily workload was only four hours. Every two working days shifts, clothes, shoes, hats, gloves, masks and other equipment were provided free of charge by Sihai Coal Industry. Each coal mine has a canteen. If you only need to spend a few cents a symbolic amount of money, you can enjoy a dish of one meat and two vegetables, and the meals are even more open and full.

Zhu Youjian knew that the salary of coal miners was real hard-earned money. Every day, he had to risk his life to drill into the dark underground tunnel, chiseled the coal one by one, and then his partner filled the coal with baskets, crawled and dragged the coal to the ground.

Moreover, during the coal mining process, accidents may occur at any time, such as rising from the roof (landstorm), permeable water, and often digging down with a pickaxe to dig open the groundwater next door. Then the flood breaks through the obstacles of the soil and rocks, instantly flooding the entire mine cave, and absent from the entire operation level will be spared.

In the 14th year of Chongzhen, a water-permeable accident occurred in the Pingdingshan Coal Mine of Sihai Coal Industry. All 15 absenteeism on duty were killed. Although people were commonplace in the era when life was as low as grass, people were already commonplace. Except for the family's sorrow, others were basically indifferent, but after the news was passed to the palace, Zhu Youjian still felt extremely uncomfortable.

Although he knew very well that such accidents were inevitable, he still struggled to accept this tragedy when he thought that more than a dozen living lives would disappear in an instant.

To this end, Zhu Youjian issued a special order that Sihai Coal Industry should make generous compensation for the absenteeism in the event of death and absenteeism, and in the future, it should make as many as possible ideas and preventive measures in terms of production safety to avoid similar tragedies as much as possible.

The absenteeism hired by Sihai Coal Industry can retire as long as it is 50 years old. After that, Sihai Coal Industry will pay the pension every month, and the amount will be paid at 60% of the time it is working, and will increase as prices rise in the future.

Zhu Youjian's order was only directed at the industries under the name of the Sihai Commercial Bank, and the court officials did not discuss this.

Under the extremely generous material conditions and treatment, the vast majority of scholars and officials still have no shortage of conscience. After Zhu Youjian frequently mentioned the importance of the vassal, the officials gradually accepted the rationality of eating meat and drinking bones and drinking soup in the situation.

Without the hard work of the people, where will their glory and wealth come from?

In order to allow future generations to enjoy wealth and honor forever, this is the long-term way. A few years ago, weren’t the thieves who rose up everywhere, composed of the thieves?

It was because the court did not treat them well that the grass-roots people became angry and used hoes, wooden sticks, and rakes to smash the masters and noble ladies who were bullied over their heads and saw them in the grass into piles of mud.

Zhu Youjian's straightforward words gradually spread in the Ming Dynasty officialdom, and most officials were alert because the scenes the emperor said were vividly visible, as if they were yesterday.

The coal mined by Sihai Coal Industry will be refined into coke for use in the bureau to smel steel. The remaining coal surfaces and small charcoal blocks will be sold in the coal yard. These coal surfaces will be bought by the people for heating and cooking.

"The bottom coal is like noodles, mostly called "the wind of the air". Milk and water are mixed into cakes and put into the furnace. After it is burned, it is the same as the Ming coal, and it will never die day and night. It is half served for cooking."

In addition to the above-mentioned traditional handicraft industry, with the stability and improvement of the situation in recent years, some emerging industries have also appeared in various places, and these industries are basically officially promoted.

For example, the construction industry, water conservancy facilities construction industry, fur processing industry, road and bridge exploration and construction industry, and animal husbandry industry. These emerging industries are basically organized by Sihai Commercial Bank, and only one of them is divided into the construction industry. This business is divided by a construction team jointly established by Tian Hongyu, Zhou Kui, Yuan Yerang, Zhang Guoji and other national and foreigners.

As he tasted the sweetness in the new residential construction project in the capital and residential project in the capital and interest, several national relatives simply devoted themselves to the construction team again, expanded the scale of the construction team, and then solicited business in the Gyeonggi area to obtain more profits.

In view of the idea that the fertilizer and water will not flow from outside the field, Zhu Youjian waved his hand and packaged all the projects that needed to be built by talents introduced in the Imperial College to them. The entire project will be constructed according to the drawings provided by the Ministry of Industry.

The total budget of this project is more than 700,000 taels, and the overall project is expected to end in two years. As for how much money the national relatives can earn, Zhu Youjian didn't care. He only hoped to see the birth of professional teams in various industries with stronger professionalism and stronger strength. The rest of the details have their own rules. The process of any thing cannot be full of sunshine. As long as it can promote the healthy development of society, everything else doesn't matter.
