First of all, Jiang Xinwei tested all the metal components he would come into contact with with the test electricity, and after seeing that there was indeed no power and there was no danger of electric shock, he began to use a screwdriver to open the switch box cover, and quickly took out two black circuit boards from inside.

Although he was fully prepared for the power supply to burn out the equipment, after taking them into his hands, Jiang Xinwei was still shocked by their bad appearance: not only the triode and diode were broken, but also some resistors and capacitors were burned out, and even the PCB was burned in many places...... It can be said that these two circuit boards are useless and can only be thrown away as garbage!.

Zhang Guohua, who was standing beside him and didn't understand electronic technology, shook his head after seeing these two pieces of black and slimy things.

At this time, a miner covered with black soot ran over from a distance, rushed to the communication room and saw Zhang Guohua here, he couldn't help but be stunned, but then asked: "Mine Manager Zhang, have the telephone maintenance personnel sent by the superior arrived?...... Mine Manager Wang sent me to inform and urge the people in the communication team, and he said that if the telephone is repaired quickly, he may be able to get through to the phone in the mine...... Just now, we found three injured miners at the entrance of the mine, and also checked the communication lines in the mine, and found that although the cable of the No. 4 mine was buried by mud and rock, it did not seem to be broken. …… , please urge the people in the communication class, please hurry up and repair, I will go upstairs and report to Mine Chief Guo!"

The mine manager Wang mentioned by the miner was the mine leader who personally commanded the rescue at the No. 4 mine road site, and he was also a deputy mine manager. As soon as the accident occurred, the mine leader arranged for him to lead all the men who could organize to form a rescue team to excavate the No. 4 mine road where the accident occurred.

Although this kind of action is very blind and the effect may not be good, this kind of action can give the miners and their families the greatest psychological comfort, and can stabilize people's hearts to the greatest extent. It was also their rescue that found three wounded miners near the mine crossing.

Soon after the miner rushed upstairs, he rushed down with Mine Chief Guo and others, and strode towards the mining area.

One of the young men ran to the communication room and said to Zhang Guohua inside: "Mine Chief Zhang, Mine Chief Guo, they have gone to the No. 4 mine crossing." Just now, Mine Manager Wang sent people from the rescue site to report that they had rescued three injured people from the mine crossing, and built Yì Guo Mine Manager to concentrate all rescue forces at the No. 4 mine crossing. Mine Chief Guo and the others have unanimously agreed to Mine Manager Wang's construction and confirmed his construction as the final plan. …… Mine Manager Guo asked you to go to the radio room, and the radio informed all the young women and people who knew how to take care of the wounded at the No. 4 mine crossing, and at the same time asked you to comfort the families of the miners on the radio, please don't ......be in a hurry."

Zhang Guohua had already listened to the miner's report just now, and had a certain understanding of the situation, and after listening to the young man's words, he immediately said: "I know. …… You sue Mr. Guo and I agree with this final plan, and I ask you to pay attention to your safety. …… I'll go to the radio room right away. ”

The young man, Secretary Tang, agreed, turned his head and chased after the group of people in front of him.

Zhang Guohua said to Jiang Xinwei, who was inspecting the circuit board: "Xiao Jiang, I have to go to the broadcasting room, and I will leave the matter here to you." Please be serious, if you help us fix the phone, our mining department will definitely take credit for you. ”

Jiang Xinwei glanced up at Zhang Guohua and said, "Mine Chief Zhang, don't worry, I will work hard." ”

……

With the rescue of the three wounded, the confidence of the rescue team has been greatly increased, and with the arrival of Mine Chief Guo, everyone is more motivated.

Mine Manager Guo personally went down to the depths of the mine and dug with the miners, carrying stones and soil together. It's just that after digging for a while, Mine Chief Guo's heart began to feel inexplicably empty, and he continued to be busy. The more he dug in, the more difficulties he encountered, the larger the rocks encountered, and the slower the progress of the excavation, the more confident Mr. Guo became.

Especially after seeing the soil under his feet getting wetter and wetter, he finally doubted whether this final plan formed because of Deputy Mine Manager Wang's strong construction was scientific.

"In case these more than 40 miners can't be rescued in time, then I, the mine manager, ......" Thinking of this, Mine Chief Guo's heart suddenly contracted, and his face became more and more pale.

"Mine Chief Guo, what's wrong with you?...... , there is not enough oxygen here, you take a break first. At this time, Chief Engineer Ma, who was also on the front line of the rescue, shouted loudly to a young man next to him, "Secretary Tang, hurry! ”

Mine Manager Guo did not brace hard, and with the support of Secretary Tang, he walked out of the mine with the rotation of personnel.

As soon as I sat down, I saw squad leader Li coming out of the computer room covering his face and walking over.

"Li Jinqiu, why are you here? Has the person sent by the superior to repair the phone arrived?" Seeing Squad Leader Li, Mine Chief Guo hurriedly asked, anxious that he didn't pay attention to the constipated appearance at all, and didn't even think about why the other party was covering his face.

Li Jinqiu approached Mine Chief Guo and said very aggrievedly: "Mine Chief Guo, how can you let the person who delivered the newspaper repair the telephone? He, Jiang Xinwei, belongs to the postal service, and only telecommunications personnel can repair the telephone, and the two have no boundary, and he is not qualified to repair the telephone at all. ”

Mine Chief Guo's heart chuckled, and he blurted out: "He is really not qualified to repair the telephone, isn't he from the Post and Telecommunications Bureau?"

Li Jinqiu hurriedly said: "Not everyone in the Post and Telecommunications Bureau is qualified to repair. It's okay if the phone is fixed, but if it doesn't fix well, it's a big problem. Mine Manager Guo, don't you know that as soon as he entered the computer room, he waved your signboard, saying that you ordered him to repair it, and told all the computer room personnel to get out of the way. I only asked him if you could fix the newspaper you delivered, and he slapped me in anger, and said that whoever opposed him was against you, Mr. Guo. Look at my face, if it weren't for the overall situation, I would have beaten him to death!

Mine Chief Guo stared at Li Jinqiu for several seconds, and suddenly ordered Secretary Tang beside him: "You go to the communication room of the Ministry of Mines building immediately! You said to Mine Chief Zhang, please ask him to urge his superiors to send maintenance personnel over again." If they arrive, they want people we give to people, they want things we give things, regardless of the price, we must repair the switch as soon as possible!"

Secretary Tang was about to leave, and Mine Chief Guo said again: "You also told Mine Manager Zhang not to let the young man who delivered the newspaper fix the phone." You warn that young man that if he breaks the equipment in our computer room and delays our rescue time, he will be held responsible. …… , now people's lives are at stake, not him...... It's not the time for him to try his hand!

"Understood!" Secretary Tang glanced at Li Jinqiu, and then left in a hurry.

Li Jinqiu, who thought that he had helped Mine Manager Guo and succeeded in suing, flashed a trace of pride in his eyes, and hurriedly followed.

Looking at the back of Li Jinqiu leaving, Mine Chief Guo snorted fiercely.

Obviously, he didn't really want Jiang Xinwei to stop, because time was too precious, and if the phone was repaired one second earlier, they would be able to modify or adjust the rescue plan according to the situation one second earlier, and the trapped miners would be rescued one second earlier.

However, two people reminded him that the young man from the post and telecommunications office might repair the telephone and delay time, which made him have to think about the consequences: If he really repaired it, wouldn't he be regarded by others as obstinate?

……

Jiang Xinwei, who was repairing the switch in the computer room, naturally didn't know that the situation had changed, and he didn't know that Mine Manager Guo deprived him of the right to continue repairing the switch because he was afraid of taking responsibility.

He was staring at the two black circuit boards in front of him.

In the end, he sadly confirmed that not only could he not fix them, but he could not even tell how well the electronic components on the circuit board would perform in a short period of time.
