Liu Minghua originally wanted to sit at home and have fun for a while, but things came again. Cheng Yanjin sent his son Cheng Chumo, and 100,000 people rushed over, saying that when they were mining mountains and rocks recently, they had encountered a lot of things and had several accidents, and they were all a little helpless now.

After Cheng Chumo finished speaking, he took out another piece of paper and said to Liu Minghua: "Minghua, to sum up, the following points are summarized. You need to give an answer to a few points, otherwise, the blasting speed will definitely slow down. ”

Liu Minghua looked at it carefully and said with a wry smile: "The onlookers were injured by the flying rubble? Damn, didn't you evacuate the crowd? ”

Cheng Chumo smiled bitterly: "Minghua, but those mountains, the woods are dense, there is no way for us to notify every villager, besides, some villagers don't have a thing that can make stones fly!" You look at ......"

Liu Minghua rubbed his head painfully and said, "This is not a joke! When carrying out blasting operations, it is necessary to notify all personnel working in the dangerous area and downwind direction and those who are not related to the blasting operation to evacuate in time! I always feel that there is no problem, so I can detonate! ”

Cheng Chu said silently: "That...... What if the villagers don't listen? ”

Liu Minghua said angrily: "You are pigs? What about your people? When blasting, someone must set up a sentry, barricade or warning sign at a conspicuous place at the boundary of the danger zone! Someone is standing guard, and those villagers can't force themselves to break through the defense line, right? ”

Cheng Chu was dumbfounded and said, "Huh? Such? ”

Liu Minghua glared: "What do you want if you don't do this?" By the way, this is for those villages! Our people also need to take precautions. Such. For the safety of blasting personnel, it is necessary to set up a solid hiding place in a suitable place, and set up a shelter to avoid guns. So much wood, don't sue me for not building a shed! ”

Cheng Chu was silent for a while and said: "Yes, if you are afraid of flying stones in the sky, why not build a shed?" Really good idea! ”

Liu Minghua said angrily: "Didn't I tell you?" You guys don't even bother to carry it out? It's a blast, it's going to kill people! You must not take this kind of chance! That way, if you find it a bit of a hassle to run around, then you can dig a pit and put a row of logs on top. Then put on a thick layer of soil! In this way, even the shells will not be damaged. Not to mention the stones in the sky! ”

Cheng Chu said silently: "Dig ...... Pit? How do I get there? ”

Liu Minghua looked up to the sky and sighed, and then said angrily: "I'll go, haven't you seen a mouse digging a pit?" I won't dig a pit to find a professional grave robber! Don't sue me that there are no tomb robbers in Datang! As for how to set up that tunnel, I'll draw you a diagram later. About the protection from the flying stones in the sky. No problem, right? ”

Fortunately, the onlookers were only injured these few times. If you want to kill someone. Then this water conservancy construction project may be dragged down!

Cheng Chumo smiled: "No...... No problem. However, there is also how to install gunpowder and how to detonate it, which is a teaching of one master and one method. It's a bit of a mess. ”

Liu Minghua smiled bitterly: "I have taught more than 50 people in total, isn't it enough?" ”

Cheng Chumo said helplessly: "Your Majesty saw that the gunpowder was so powerful, so he expanded the scale of water conservancy construction...... Originally, thirty or so people were enough, but now it may be three hundred! In this way, there are not enough people. My father asked each of the fifty men to bring six apprentices, and the result was ......"

Liu Minghua said angrily: "The result must be tragic!" Those fifty people, even if they master it, may not be able to teach their apprentices what they know. Hey, forget it, it looks like I'm going to write a standard operating procedure. I remember when I wrote it, right? It doesn't seem that fine, right? ”

Liu Minghua thought for a while and said: "Mainly pay attention to the following points: After the blast hole is laid, you have to start charging, right?" However, before charging, the stone powder in the blast hole should be removed with a cannon stick, and then the charge should be carried out according to the depth of the blast hole. Tell them, when charging the medicine - put the medicine to be loaded one section next to the other, and then gently push it into the eye with a cannon stick, the force should be moderate, not too loose and not too tight. If it is too loose, there is air in it and there is no force to explode, if it is too tight, the gunpowder is hit by Yan zhòng, maybe it will explode! Remember, you must use wooden cannon sticks, not metal! As for this strength, those fifty or so people understand it, and I don't need to be verbose. After the strength is about the same, then it's time to fill in the mud, and be careful not to break our fuse! Pay attention to the thickness of the clay, if the seal is not good, the explosive force will be greatly reduced! These, it should be clear, right? ”

Cheng Chumo nodded and said, "I know everything you say that." But when it comes to blasting, the scene is messy......"

Liu Minghua sighed: "Grandma's, this is a typical organized and undisciplined person!" In this way, it has to be organized! Divide these blasters into groups! Before the blasting operation, the team leader should organize the blasters to study carefully and discuss the blasting plan and safety issues! Then do a good job of dividing the work and arranging the work. In this way, every blaster has a bottom in his heart! Otherwise, some people are obviously doing the right thing, but they don't know what is wrong in their hearts! Some people obviously don't do it well, but they think that their blasting is good! In order to avoid the above situation, it is necessary to divide into groups! Only by supervising each other, learning from each other, researching and making progress with each other can we do a good job in protecting each other. I'll write it down for the specific implementation! Still have questions? ”

Cheng Chumo kept nodding: "Yes, yes, a few people look at each other, there will definitely be no problem." As for other questions? Well, it's just that our blaster's safety equipment doesn't meet your requirements. People still don't wear hats, long shirts, loose shoes......"

Liu Minghua said angrily: "How can this work? This must be agreed! Must wear our custom-made rattan hard hats! It must be neatly dressed, not a long shirt! Especially shoes, you have to wear the kind that has been specially designed with laces!

Otherwise, after the explosives are lit, wearing a long shirt and cloth shoes, you accidentally slip and fall, and you will die! If you don't wear a hard hat, even a small pebble will make the blaster bleed! ”

The Tang Dynasty, of course, did not have the helmets of later generations. Originally, Liu Minghua wanted to use metal to build a helmet, but on the one hand, the cost of metal is too high, the speed is slow, and the most important thing is that if the metal collides with gunpowder, it is very easy to explode, so Liu Minghua made a rattan woven helmet. This kind of hat is actually very safe, and it also has good elasticity and toughness.

Seeing that Liu Minghua was so strict, Cheng Chu nodded and said, "Okay, I will tell my father about this and let the blasters strictly enforce it!" ”

Liu Minghua sighed: "I know that your father thinks it's normal to kill a few people!" If on the battlefield, there is nothing wrong with that. However, when we engage in water conservancy construction, this is peaceful construction, so we must pay attention to safety and not just kill people. ”

Cheng Chumo smiled bitterly: "My father, naturally, didn't listen to my words. It's just that if it's your words, my father will definitely listen to them. ”

Liu Minghua nodded, looked at the safety accidents again, shook his head and said, "Look at this, it just exploded, and you were busy going up to mine stones?" Crazy? How could there be no flowstones coming down from the mountain?

Tell them - half an hour after the detonation, wait for the smoke to clear, go in two blasters, and check if all the gunpowder has exploded? If there is no problem, let the workers come up and carry the stones! Don't be in a hurry, you know? ”

Cheng Chu scratched his head silently: "Oh, so you have to wait for a while? ”

Liu Minghua said: "That's not nonsense? The gunpowder has just exploded, and the sky is full of dust, what do you say you are going to do? I like to eat haze so much, and I have the ability to go to Beijing and Tianjin! ”

Cheng Chumo wondered: "Ah, where is Beijing and Tianjin? ”

Liu Minghua rolled his eyes: "Beijing and Tianjin? Not here, in heaven! The sky is full of clouds and mist, and that is 'haze'! Well, without saying that, I'll see what else is wrong? ”

Liu Minghua looked at it for a while, and then said angrily: "What is the situation with you?" I have repeatedly ordered that blind artillery must be handled carefully and correctly! If blind guns are found or suspected to have blind guns, they should be reported immediately and dealt with in a timely manner. If it cannot be dealt with in time, obvious signs should be set up nearby, and corresponding safety measures should be taken. Then find a blind cannon handler to deal with it!

During the processing process, it is necessary to strictly abide by the operating procedures, and be cautious and pay attention to safety! When dealing with blind guns, irrelevant personnel are not allowed to be present and should be on alert at the boundary of the danger zone. No other work is allowed in the danger zone! If you have to be so responsible, something big will happen! ”

Cheng Chumo immediately nodded, indicating that he would deal with it seriously.

Liu Minghua shook his head: "It's not a mess like this." All those who participate in the blasting must have special training, and then they have to pass a certain exam before they can take up their posts! After the blasting personnel operation qualification certificate, the blasting operation can be carried out, and the blasting equipment can be obtained with the certificate. Otherwise, you will not be allowed to work! ”

This should be the first qualification certificate in the history of China! However, Liu Minghua feels that this work permit must be had!
