ps: Thank you for the pain is not a sin, the first time I saw the genuine 555, the dream of the tide of the year, the wisdom of the sacred heart, the reward of the merry musician, ask for Monday's recommendation votes, and reward!

......

Thinking of this, Jiang Feng immediately shouted loudly: "He Jingkun, hurry up and stop the electric drill in your hand, gas has been found here...... Gas gas. Pen Fun Pavilion www.biquge.info"

"What, gas?"

He Jingkun is very astute, he is more sensitive to gas than Jiang Hai, so he has some doubts, but this is not a joke, so he immediately stopped working with the electric drill.

Jiang Hai hurriedly rushed over, "Yes, gas gas has been found here, we are not sure how much gas is at the moment, so this roadway must stop the excavation first, and call the construction from the other three roadways, this is called to stop, stop!" ”

Jiang Hai is very determined.

But He Jingkun felt that hope was just around the corner, he was a very professional man who had been in the mine for seven or eight years, but he couldn't believe Jiang Hai's words so easily, and gave up the hematite he had in hand.

"Jiang Hai, forgive me for the smell, how did you find the gas, do you know the gas, my dangerous gas detector doesn't have any alarm yet."

"Maybe it's your thing that's broken, maybe it's something else, but listen to me, life never allows for jokes, you go up with me immediately, you can't stay here anymore."

Jiang Hai is still the same domineering style as before, He Jingkun was a little unhappy, pushed the hand holding his arm away, and said resolutely, "Gas gas is rare in iron ore veins, and the probability is very small, so Manager Jiang, if you are afraid and worried, you go up first, I'm collecting a little sample, and I'll go up again, really..."

"I'm a fart. Quick, together. ”

"I'm not leaving, you have to believe in my profession." As He Jingkun spoke, the electric drill in his hand turned on again.

He stretched forward, three clicks.

Immediately after, the watch in his hand began to beat, and the red warning light flashed clearly.

Jiang Hai yelled, "If you don't believe it, now that you see it, call the police." Let's go, hurry! If we don't leave, we'll die! ”

Jiang Hai stretched out his hand and snatched the electric drill, turned off the "switch", and pulled He Jingkun to run out.

……

Although He Jingkun has never encountered a mining disaster before, and he feels that it is so easy to encounter a mining disaster, he has also read a lot of information about various mining disasters when he is usually fine, after all, his job is to deal with mineral resources, so he pays special attention to the protection of his own safety.

In this regard, he is particularly vigilant.

But. He Jingkun was indeed negligent, in the mine where the gas existed, He Jingkun did not anticipate the possible danger in advance. It's completely leaving his own safety behind.

It means that if Jiang Hai hadn't struggled to pull himself out just now and stopped him from continuing his work, he would probably have been burned to the ground by the fireball that was about to come out.

Oh, yes. He Jingkun has seen the accidents in those mines, and it is not just the operation of the electric drill, which hit the hole where the gas is hoarded. As soon as the gas leaks out, it will explode when it encounters an open flame.

Once the gas explodes, the power is quite terrifying, even compared to the charge of hundreds of kilograms. The giant bombs of medicine are not at all, and people can hardly survive within the reach of such explosions!

Needless to say, this roadway is like what Jiang Hai said, and it is extremely dangerous.

"Jiang Hai, I He Jingkun's life was saved by you, I thank you."

After He Jingkun came out, he suddenly knelt in front of Jiang Hai.

I don't believe Jiang Hai, and I also said that people are timid and afraid of death, if it weren't for Jiang Hai, it would be me who died now.

He Jingkun was full of sincerity, Jiang Hai didn't complain about him at all, this kneeling Jiang Hai felt that he was tormented by himself, and hurriedly pulled He Jingkun up, "Brother Jingkun, where are you kneeling for me, let's go to the mine together, then we have to help each other and support each other, people say that only those who have fought together in the mine and in the army are called brothers, because they bind life and death together, you thank me, don't treat me as a brother." ”

"I treat Brother Jingkun as a brother, you told me a lot about this, I just found a gas detector alarm and told you the situation, it's not as serious as you said."

Jiang Hai naturally said it easily, but He Jingkun wrote down this kindness.

"Jiang Hai, then I will call you brother directly, brother, if there is any use in the future, you must tell me, and I He Jingkun will definitely do it."

"Where to speak, where to speak. But Jingkun, I would like to ask, in the current situation, should we stop this laneway, that is, give it up? ”

Jiang Hai and He Jingkun are here, and the action of you kneeling and me helping you up has already recruited other absenteeism.

After hearing about Fang Cai, everyone admired Jiang Hai even more, life, that is the most precious thing, Jiang Hai is not for money, but more concerned about the life of absenteeism, for these absentee workers who hang life and death on their belts every day, Jiang Hai is a good person and a good boss.

Deng Shaolin even said a lot of good things about Jiang Hai, and even expressed his loyalty, enviously those absent workers wanted to follow Jiang Hai.

Jiang Hai scratched his head, he doesn't have the qualification for mine development, but Jiang Hai will definitely have this qualification in the future, if he succeeds in logging this vein, the mining license, Jiang Hai will definitely find a relationship to deal with.

Regarding Jiang Hai's question, He Jingkun and other absenteeism gave an answer at this time.

In this isolated underground space, one of the four tunnels should store extremely rich gas gas, and the excessively concentrated gas gas will not explode after exceeding the explosion limit of 15%, and it will only deflagrate after it is fully combined with sufficient oxygen.

In other words, it is not possible to work with an open flame. As long as there is no open flame and a conservative approach is adopted, the last roadway can still be mined.

Even so, there is a certain amount of danger.

Jiang Hai saw it through the bat hat at that time, and it was obvious that the concentration of gas in this space had exceeded the explosion limit of gas, and because the concentration of gas gas was too high, all the oxygen was excreted, so it was safe to not contact with enough oxygen and cut off oxygen.

Therefore, the eruption also occurred because there was enough oxygen in the tunnel outside the cave entrance, so this outward ejection was formed.

Now to work, that is, in a non-oxidizing state, only the operator through the instrument artificial oxygen, and then bless the operation tools that do not produce electric light, so that no matter how fierce the gas gas is, it will eventually be useless.

But this involves another problem, in this case, the cost of mining will undoubtedly increase even more. The oxygen in the cave needs to be pumped out first, and the mining is completed in a non-oxidizing state.

If it's a gold mine, it's just a silver mine, is it worth it for a hematite?

Whether it can be opened or not, that is the scope of consideration of Jiang Hai. In short, the absentees said that everything supports Jianghai's decision, and if it is mined, the brothers will have to go on it no matter how hard it is, and if they don't open it, it's okay.

However, if you don't mine, Jianghai is equivalent to giving up the possible ore veins under this roadway!

"Ignore this roadway for now, the other three roadways are waiting for a call, you can survey again to make sure that there is no gas gas, and then logging."

Jiang Hai finally gave the order. (To be continued.) )
