Chapter 305

Chen Feng clicked his tongue in wonder: "What the heck is this? Why does it look like a UFO? If I hadn't seen it sawed open with my own eyes, I would have thought it was a UFO!"

Fang Yang had long guessed this would happen, and a faint smile appeared on the corner of his mouth.

"I told you, it's just coal gangue. Its components are mainly silicon, and some carbonaceous matter. You can check it online; coal gangue is this color, grayish-black!"

The cameraman still couldn't believe it: "But even if it's a stone, why is it this shape? It doesn't make sense!"

Fang Yang smiled and explained: "What if I say it was polished?"

As soon as these words came out, they couldn't understand it even more, looking dumbfounded.

"First of all, it can be certain that it is a piece of coal gangue. The reason it became this shape is purely nature's craftsmanship."

"Long-term crustal movement caused the coal gangue to be subjected to rock pressure. In this process, long-term pressure and friction caused it to become relatively smooth. As for this shape, it's purely a coincidence!"

"In other words, it has no value except for its shape, but in my opinion, it is worth its weight in gold!"

"Why?" The cameraman looked puzzled.

Fang Yang's expression suddenly became solemn: "Coal gangue is a companion of coal. Now that I've dug up coal gangue, it shows that there is a high possibility of coal here. And after crustal movement, the coal gangue has run to such a shallow soil layer, and the coal layer below may also be very close!"

"Of course, it doesn't exclude the possibility that this thing was buried here by someone, but this possibility is very low!"

Old Cheng didn't quite understand and asked uncertainly: "Does it mean that if there is coal gangue, there is coal, and there is coal below?"

Captain Wang took a deep breath: "Fang Yang, you don't mean to say there is a coal mine below!"

Hiss~~

Everyone finally reacted and couldn't help but gasp.

If a coal mine was discovered, that would be another major resource.

Old Cheng still couldn't accept it: "No way, this is all sandstone, trees can't even survive, how could there be a coal mine."

Fang Yang smiled: "It's not certain yet. I have to dig and see to know. Maybe countless years ago, this place wasn't like this, but lush with trees!"

After saying that, he jumped into the cab and started digging.

Following the place where the coal gangue was just discovered, he continued downward.

However, after digging for a while, the so-called coal did not appear.

Fang Yang was a bit puzzled—where was the coal?

Just as he was puzzled, the bucket shoveled into the soil.

BOM~~!!

A violent explosion sounded.

The entire excavator shook.

The glass window in front was shattered by the explosion.

A pile of grayish-brown soil was blown out of the mud pit, flying all over the sky.

Fang Yang was dumbfounded!

Everyone behind him was dumbfounded!

This sudden explosion caught no one off guard.

After they came back to their senses, it was already over.

Captain Wang rushed up: "Fang Yang, are you okay? Are you hurt?"

Fang Yang watched Captain Wang talking non-stop, but he couldn't hear a word; his ears were full of buzzing sounds.

At this moment, it felt like returning to the third day of the competition, the scene of digging landmines at that time.

Although digging landmines before was an accident, that place was a relic of the War of Resistance, so it wasn't strange to have landmines.

But here? This was a godforsaken place; where did the bombs come from?

He would never have imagined it!

Seeing that Fang Yang was fine, everyone rushed over to ask.

Fang Yang looked at their anxious expressions and smiled helplessly: "Don't worry, I'm fine, just can't hear anything, it will be fine in a while!"

【Popularity】+1+1+1+1.

——【What's the situation? Dug up a landmine again? This unlucky kid, let you show off every day, now it's good, showing off and getting bombed! Remember in the future, don't show off all day long. You've shown off all the showing off, and even God can't stand it. Cough cough~~ you won't scold me, right!】

——【Why would I scold you? You said what we wanted to say, but having said that, is Fang Yang okay? I see his expression was stunned by the explosion, don't blow his brain up, otherwise, there will be no one to broadcast the show for us.】

——【Exciting! You never know when you will die inexplicably. Those who envy Fang Yang, open your eyes and see now. If you were asked to go and dig a landmine that would explode, would you still go, dear? And it's the kind that explodes suddenly, isn't it a surprise, isn't it unexpected!!】

——【That coal gangue sawed off above is a pity. If it wasn't sawed off and brought back to collect, it would be quite good. At least take it out and tell others it's a UFO, I guess not many people wouldn't believe it. At that time, you can also take it out to fool girls, saying you are from outer space and want to take her on a space trip, beautiful!】

Seeing that Fang Yang was fine, everyone felt relieved.

But just then, the cameraman suddenly sniffed: "What's the smell? So choking! Cough cough~~"

The others also sniffed curiously. Upon smelling it, the scene immediately came with bursts of coughing sounds.

Cough cough~~

Cough cough~~

"What's going on, why is there such a choking smell!"

"Eh~~ look behind you, it seems to be smoking."

Everyone turned their heads to look behind.

I saw a lot of black substances blown out of the place where the explosion just happened.

Everyone recognized at a glance that this was coal.

"Holy crap! There really is coal!"

"No way, is there really a coal mine below?"

"No, didn't you notice that the coal mine is smoking!"

Fang Yang suddenly reacted at this time and shouted: "Oh no! Cover your nose quickly, this is the smell of burning coal, it's poisonous!"

His brain was a bit confused from the explosion just now.

Looking at the place of the explosion again, there was more and more thick smoke, and he could faintly see the fiery red coal inside burning.

Fang Yang immediately jumped out of the car and shouted: "The coal just exploded and caught fire, evacuate quickly!"

Old Cheng was a bit anxious: "Caught fire? No way, there is no water in this place, how to put out the fire? Should we call the fire alarm first?"

Everyone covered their mouths and noses and stood back, at a loss.

Where could there be water to rescue in this godforsaken place? Captain Wang immediately called the fire brigade to come and help put out the fire.

After the call, he asked curiously: "Why did it explode just now?"

Fang Yang also wanted to know the answer to this question, being bombed inexplicably and almost dying here.

However, just then, he inadvertently saw a broken little tube on the ground.

He knew what this was at the first moment.

Detonator!

Fang Yang's scalp tingled and he couldn't help but burst out a swear word: "Holy crap!"

But on second thought, where did the detonator come from in this place!

Just then, the coal was already burning completely, and he also saw a small hole under the coal.

In an instant, he had a bold guess!

Immediately after, he picked up the No. 8 detonator on the ground: "Captain Wang, look what this is!"

"Hiss~~ Detonator? Where did the detonator come from here?"

Fang Yang pointed to the small hole in the coal again: "I suspect that someone discovered the coal mine below and secretly dug a mine tunnel to mine it. This detonator was used by them for blasting!"

"This... is too unlucky, who would have thought there would be a detonator here!"

"Brother Wang, the problem now is not this, but the coal has caught fire!"

Captain Wang was stunned: "What do you mean? Won't the fire brigade be here in a while, and it will be extinguished?"

Fang Yang shook his head: "You think too simply. If someone really dug a mine tunnel here, then after it was blown open, oxygen will definitely enter."

"When the coal in the coal seam comes into contact with the outside air, the oxygen molecules in the air form physical and chemical adsorption on the coal surface, causing the coal surface temperature to rise slowly."

"In addition, there is the hot weather outside, as well as the high temperature brought by the burning in front of us. It will aggravate the temperature of the coal to exceed the critical value. Once the oxidation of the coal intensifies, the coal temperature rises rapidly, and in this process, the coal will release flammable gases such as hydrocarbons, carbon monoxide, and hydrogen."

"If there is no accident, in the places we can't see now, the coal is already in a red-hot state, and its temperature is still rising. Once the temperature reaches the spontaneous combustion critical value of 300-350 degrees, an open flame will appear."

"Plus the flammable gases released during coal oxidation, as long as there is an open flame in one place, the fire will spread to the surroundings. So what we see now is only burning in one place, but in fact, many places below have already started spontaneous combustion, but it hasn't been transmitted to the ground surface yet."

However, just as he finished speaking.
