“Dad, I’ll go down below in your place,” he said with a smile, then strode out toward the smoking mouth of the shaft.
A helicopter pilot recalled later that during a low-altitude flyby of Shaft No. 2, a final sweep of the area, he thought he saw someone near the opening, a black silhouette against the red glow of the ground fire. The figure seemed to be heading down the shaft, but in the next instant there was only red light, and nothing else.
People really were dumb in the past, and they really had a tough time.
Do you know how I know? Today we visited the Mining Museum. What impressed me the most was this:
They had solid coal!
First, we had to put on weird clothing: there was a helmet, which had a light on it, connected by a wire to a rectangular object that we hung at our waists. I thought it was a computer at first (even if it was a little large), but it turned out to be a battery for the light. A battery that big could power a racing car, but they used it for a tiny light. We also put on tall rain boots. The teacher told us this was the uniform that early coal miners used for going down the mines. Someone asked what “down the mines” meant, and the teacher said we’d find out soon enough.
We boarded a metallic, small-gauge segmented vehicle, like an early train, only much smaller and powered by an overhead wire. The vehicle started up and soon we entered the black mouth of a cave. It was very dark inside, with only an occasional dim lamp above us. Our headlamps were weak as well, only enough to make out the faces right beside us. The wind was strong and whistled in our ears; it felt like we were dropping into an abyss.
“We’re going down the mine now, students!” the teacher said.
After a long while, the vehicle stopped. We passed from this relatively wide tunnel into a considerably thinner and smaller spur, and if not for my helmet, I would have knocked a few lumps in my head. Our headlamps created small patches of light but we couldn’t see anything clearly. Students shouted that they were scared.
After a while, the space opened up in front of us. Here the ceiling was supported by lots of columns. Opposite us, there were many points of light shining from lamps like the ones on our helmets. As we drew closer, I saw lots of people were at work, some of them making holes in the cave wall with a long-bore drill. The drills were powered by some sort of engine whose sound made my skin crawl. Other people with metal shovels were shoveling some sort of black material into railcars and leather satchels. Clouds of dust occasionally blocked them, and lanterns cast shafts of light through the dust.
“Students, we’re now in what’s called the ore zone. What you see is a scene of early mining work.”
A few miners came toward us. I knew they were holograms, so I didn’t move out of the way. Some of them passed through me, so I could see them very clearly, and I was astonished.
“Did China hire black people to mine coal?”
“To answer that question,” the teacher said, “we’ll have a real experience of the air of the ore zone. Please take out your breathing masks from your bags.”
We put on our masks, and heard the teacher say, “Please remember that this is real, not a hologram.”
A cloud of black dust came toward us. In the beams from our headlamps I was shocked to see the thick cloud of particles sparkling. Then someone started to scream, and like a chorus, a lot of other kids screamed as well. I turned to laugh at them, but I, too, yelped when I got a look: Everyone was completely black, apart from the portion the masks covered. Then I heard another shout that turned my hair on end: It was the teacher’s voice!
“My god, Seya! You don’t have your mask on!”
Seya hadn’t put on his mask, and now he was as completely black as the holographic miners. “You said over and over in history class that the key goal was to get a feel for the past. I wanted a real feel!” he said, his teeth flashing white on his black face.
An alarm sounded somewhere, and within a minute, a teardrop-shaped micro-hovercar stopped soundlessly in front of us, an unpleasant intrusion of something modern. Two doctors got out. By now, all of the real coal dust had been sucked away, leaving only the holographic dust floating around us, so their white coats stayed spotless as they passed through it. They pulled Seya off to the car.
“Child,” one doctor said, looking straight into his eyes. “Your lungs have been seriously harmed. You’ll have to be hospitalized for at least a week. We’ll notify your parents.”
“Wait!” Seya shouted, his hands fumbling with the rebreather. “Did miners a hundred years ago wear these?”
“Shut your mouth and go to the hospital,” the teacher said. “Why can’t you ever just follow the rules?”
“We’re human, just like our ancestors. Why…”
Seya was shoved into the car before he could finish. “This is the first time the museum has had this kind of accident,” a doctor said severely, pointing at the teacher and adding, before getting into the hovercar, “This falls on you!” The hovercar left as silently as it had come.
We continued our tour. The chastened teacher said, “Every kind of work in the mine was fraught with danger, and required enormous physical energy. For example, these iron supports had to be retrieved after extraction in this zone was completed, in a process called support removal.”
We saw a miner with an iron hammer striking an iron pin in one of the supports, buckling it in two. Then he carried it off. Me and a boy tried to pick up another support that was lying on the ground, but it was ridiculously heavy. “Support removal was a dangerous job, since the roof overhead could collapse at any time…”
Above our heads came scraping sounds, and I looked up and saw, in the light of the mining lanterns, a fissure open up in the rock where the support had just been removed. Before I had time to react, it fell in, and huge chunks of holographic stone fell through me to the ground with a loud crash. Everything vanished in a cloud of dust.
“This accident is called a cave-in,” the teacher’s voice sounded beside me. “Be careful. Harmful stones don’t always come from up above.”
Before she even finished, a section of rock wall next to us toppled over, falling a fair distance in a single piece, as if a giant hand from the ground had pushed it over, before finally breaking up and raining down as individual stones. We were buried under holographic rocks with a crash, and our headlamps went out. Through the darkness and screams, I heard the teacher’s voice again.
“That was a methane outburst. Methane is a gas that builds to immense pressure when sealed in a coal seam. What we saw just now was what happens when the rock walls of the work zone can’t hold back that pressure and are blown out.”
The lights came back on, and we all exhaled. Then I heard a strange sound, at times as loud as galloping horses, sometimes soft and deep, like giants whispering.
“Look out, children! A flood is coming!”
We were still processing what she said when a broad surge of water erupted from a tunnel not far away. It quickly swamped the entire work zone. The murky water reached our knees, and then was waist-high. It reflected the light of our headlamps to shine indistinct patterns on the rocky ceiling. Wooden beams stained black with coal dust floated by, and miners’ helmets and lunch boxes…. When the water reached my chin, I instinctively held my breath. Then I was entirely underwater, and all I could see was a murky brown where my headlamp shone, and air bubbles that sometimes floated up.
