An interesting story told by one miner:
It happened in Kuzbass in 197 *. Even as a young specialist, he was assigned to the brigade of an elderly hardened miner Mitrich. There was nothing special about his brigade, except for one thing. Once during a shift, they cut down a rat's nest. The rat's mother and all the rats were immediately killed, except for one. Mitrich went out to him - he fed him with milk from a saucer, when he was sick in his youth, he dissolved antibiotics in milk for him.
After such intense care on good nutrition, the rats got stronger, grew up and turned into a larger, well-fed rat named Erema. Erema settled down in the brigade, had his own ration, loved bacon and fresh bread, and dined on the hour with the whole brigade.
They worked in an old, pre-war mine, picking coal near the center of the Earth. Once it happened during a change of emergency - methane vapors exploded, the adit collapsed almost along its entire length, blocking the passage by 200 meters along with the lift shaft. Several miners were crushed like flies, the rest managed to jump back into the depths of the adit.
We came to our senses, began to calculate the chances. The air is leaking, but from the water and food supplies for six people there are only half a jar of water and three sandwiches that Mitrich's wife put for lunch. Rescuers will need at least a month to reach the miners. In the best case (do not forget - the 70s, of all rescue equipment - an excavator and shovels with chippers).
Everyone was discouraged. Suddenly two rat eyes appeared in the darkness - Erema. They shone a flashlight on him - the rat was lying on its back and waving its paws in the direction of the blockage. Then he rolled over, ran a little, back onto his back and waves. And so three times. Calling, perhaps, - suggested one of the miners. There’s nothing to do — send for him.
The rat, realizing that people were following him, no longer rolled over, climbed onto the blockage and disappeared into the crack. The miners follow him. At the top of the blockage, there was a gap, exactly the size to squeeze through the most overall one. They squeezed through. Five meters later, they look, an explosion crumpled the adit wall and opened a side passage. We climbed there. You can't stand up to full height, but you can do it on all fours. The rats waited until the last miner got into the passage and ran on. Six miners on all fours are behind him. Crawled some distance and hit the wall.
Eh, Erema, he brought me to a dead end - Mitrich summed up. Some of the miners advised to rename it to Susanin.
Come back, - ordered Mitrich, barely turned over in the adit and crawled back. Then Erema jumped and grabbed the leg of Mitrich, biting through the canvas fabric and Mitrich's calf to the point of blood. So it hangs on it, rests on its hind legs. Mitrich screams in pain. But Erema does not let him out.
But he tells us - we need to hammer, - one of the miners guessed, crawled to the dead end and began to finish him off with a hammer that happened to be with him. As soon as the hammer began to bite into the rock, Erema immediately released Mitrich and lay down beside him. Two of the most skinny ones were sent back for the tool and after an hour, replacing each other, they began to hammer the rock. The split-off layers were dragged to the rubble.
Nobody remembers how long they hammered and how many meters they walked. When the batteries sat down, they hollowed out in the dark. Exhausted so that they worked like machines - without emotion, on the machine. Therefore, when the hammer, having cut through the rock, flew into the void, no one was surprised or delighted.
When they, battered, exhausted, but alive, were raised to the surface from a nearby abandoned mine, it turned out that they had extended sixty meters in two weeks, while the rescuers could not completely clear the collapsed mine from the debris, which collapsed twice more. forcing to start clearing anew.
And Eremu Mitrich took home and from then until his rat death. Erema lived in an individual house and every morning Mitrich's wife personally changed the water in the drinking bowl, bacon and bread for everything the freshest. Erema was buried in a box made of valuable wood specially for the occasion of the miners from that brigade, and a tiny granite stone was placed on the grave with the only inscription "Ereme from 25 people" (this is how many people lived at that time in the families of the rescued six miners).
This stone still stands there.
