When the workers were mining coal mines, Ma Hongdu wrote down the accidents they were prone to and told Ma Liang one by one, so that he could organize craftsmen and take precautions. Pen ~ fun ~ pavilion www.biquge.info

It mainly includes four aspects: roof accidents, gas dust, gas, fire in the pit, and flood.

Roof disasters are the most common and prone accidents in coal mines. Among the five major disasters in coal mines (coal dust, water, fire, gas, and roof), roof accidents rank first among all types of coal mine accidents in terms of the number of occurrences and the number of deaths. With the mining of the working face, the roof rock layer above the coal seam loses its support, the original pressure balance is destroyed, and the coal seam roof is deformed and damaged under the action of the pressure of the overlying rock layer.

The presence of biogas (methane, etc.) is often present in coal seams. Biogas is prone to explosion accidents. Therefore, when working in enclosed spaces, the biogas concentration needs to be monitored frequently. If there is a certain concentration of dust in the gas, it is also possible that the explosion will be caused by sparks. The dust volume is small, but the relative proportion of the surface is large. If there is sufficient oxygen in the surrounding air, it will be very sensitive to the combustion reaction. Biogas itself is not harmful to humans, but it is sometimes accompanied by toxic gases such as carbon monoxide. If a large amount of biogas is ejected at once, the possibility of a gas explosion increases rapidly.

The worst-case scenario of a coal mine accident. Unlike a general fire, there are many combustibles (coal) in the surrounding area. If the tunnel is blocked by heat and smoke, and a lack of oxygen occurs, it usually causes significant casualties.

Floods, once the mine is dug deep, there will be water, and this is the most lacking in this era for water treatment, there is no pump, pumping water is very difficult, and the speed of work is also very slow, once the water is too much, or digging groundwater, causing the wall of the coal mine to collapse. Or if you dig into the river, the accident is worse than the fire in the pit, and there is almost no chance of survival. A large flood engulfed the tunnel in a very short time, killing all the staff. Often, survivors cannot be rescued, bodies cannot be recovered, and tunnels are abandoned.

In this era, if coal can come out in advance, then Chu will vigorously develop heavy industry, and the whole of China will also enter the industrial revolution more than a thousand years in advance, as long as the coal mining technology is slightly mature, Ma Hong can start to manufacture the steam engine, the structure of the steam engine is not difficult, the steam engine is a reciprocating power machinery that converts the energy of steam into mechanical work. A steam engine requires a boiler that boils water to produce high-pressure steam, which can use wood, coal, as a heat source. The steam expansion pushes the piston to do work.

As long as there is enough coal as an energy source, a series of inventions will spring up and appear slowly, because Ma Hong has a lot of modern knowledge, although there are some things he doesn't know how to make them, but making things you know is much easier than inventing something as new. At that time, as long as the steam engine is made and can be put into use in large quantities, Ma Hong will first put into the shipbuilding industry, build a steam engine warship, defeat the sailors of Eastern Wu first, and pacify the south.

Ma Hong's plan was to launch a full-scale war against Soochow in five years, if the steam engine iron ships were created by then, and the fleet would go down the Yangtze River, the sailors of Soochow would have no advantage under the steam engine ships of different technologies.

After Ma Hong inspected the coal mines in Taiyuan County, he and Ma Liang turned around and returned to Chang'an City.

Changan.

Ma Liang poured a glass of wine for Ma Hong, and then dismissed the dancers and maids.

Ma Hong picked up the wine glass, put it down again, and said: "Xiangyang, it's still okay as the royal capital, but if you go down to the next step, it's not the right place." ”

Saying this sentence in Chang'an City, according to Ma Liang's ingenuity, he immediately knew what Ma Hong meant, and Ma Liang said: "Does my brother want to move the capital to Chang'an?" ”

Ma Hong took a sip of his wine glass: "Actually, my favorite is Luoyang, and the second is Chang'an, but now that the coal mines in Bingzhou have begun to be mined, Chang'an is closer to Bingzhou, and it is still our territory, which is the most suitable existence as the imperial capital." ”

In the imperial capital, Ma Liang understood, and immediately nodded: "Does my brother mean to build a palace in Chang'an?" ”

Ma Hongyi raised his hand and shook it: "There is no need for the time being, but then you have to vigorously develop the economy of Chang'an, now Chang'an is the largest city in the north of Chu State, but its economic strength is not as good as that of Southern Zheng and Xiangyang, if Chang'an is used as the imperial capital, then it must be developed well." ”

Ma Liang nodded and said: "Brother Chen understands, with the mining of coal mines, if the finance of the north is extracted by 10% to build Chang'an, it will take less than five years, and Chang'an will be twice as large as it is now." ”

Ma Hong nodded, got up and walked to the map hanging in Ma Liang's room, and said to the map: "Where are Hu Du and Pang De fighting now?" ”

Under the order of Ma Hong, Hu Du and Pang De led a total of 15,000 cavalry, a total of 15,000 people, to the west into the Western Regions, to control the Western Regions, because at this time most of the Western Regions were some small ethnic groups, there were no real strong clans, and most of the Qiang tribes were subordinated to the Chu State.

Ma Liang got up and walked to Ma Hong's side, stretched out his hand to the map, and said: "General Pang De led an army to Haitou, and General Hu Du led his army to Cheshi (near present-day Urumqi). ”

"The Western Regions are far away from Xiangyang, since they have fought so far, they will send Jiang Xu to be stationed in Dunhuang County to deliver the news of the Western Regions at any time, and send a message to Pang De and Hu Du, where the army goes, there is no need to do a gentle strategy, if you dare to resist, you will be killed, and it will be difficult for 15,000 cavalry to control Nuoda's Western Regions, so you can only stop the war by killing." Ma Hong spoke slowly, drank the wine in the glass after speaking, and then licked his lips.

Ma Liang nodded and said: "Most of those alien races in the Western Regions know how to fight on horseback, but fortunately, their tribes are not too large in number, and the march of the two generals Pang De and Hu Du has not been hindered too much, and so far, everything is going well." ”

Ma Hong nodded and said: "Fighting in the Western Regions, the supply line is too long, and the consumption of 10,000 cavalry is not small, so let Hu Du and Pang De fight to support themselves in battle." ”

The so-called self-sufficiency is to burn, kill and loot, and if you don't rob or grab, how can you get grain and grass.

Ma Liang nodded and said, "Do what the king wants." ”

Ma Hong nodded, then stretched out his hand to draw a circle on the map, and then spoke: "Drive the surrendered aliens and those captured aliens to the vicinity of Cheshi and Gaochang, and establish a county, called Gaochang County." Then 10,000 infantry from Xiliang were mobilized and stationed in Gaochang County, responsible for supervising the alien races. ”

"Your Majesty, it is said that before Pang De and Hu Du entered the Western Regions, dozens of tribes in the Western Regions fought with each other, and if they were to be in one county, they would not be ...... all day."

"I understand what you said, I sent troops to attack the Western Regions, and introduced the flames of war, and the alien races in the Western Regions will definitely hate the Han people, and now if I mix these people of different races together, then they will soon transfer their hatred and sprinkle their hatred on other tribes, and the army will only be responsible for management."

"Brother Chen, I understand."

"After the establishment of Gaochang County, every three months it selects a batch of young people to come to Taiyuan County to dig coal."

Ma Liang's eyes lit up, and he said: "No, it's just that the king, if Gaochang County is established, some officials must be sent to it, who will be sent to be in charge of these things?" ”

"What do you think of sending Liu Ba there?"

"Liuba? He's not always ......."

"You've always looked at me unpleasantly, haven't you?" Ma Hong said with a smile.

Ma Liang smiled and said, "He doesn't like our brothers." ”

Ma Hong smiled: "Then send him!" This guy has the ability, but his mouth is a little damaged, and he will be given such an errand arrangement, and his mouth will be damaged again in the future, and I can't hear it. ”

Ma Liang nodded: "Brother is wise." ”
