この作品には、急ぎ避難する先山と後山とが描かれています。
In old mine slopes, rock pressure gradually increased the danger of roof falls.
Miners had to gather the warning of danger by listening to the sound from the surroundings in black slopes.
After pillars began to break or split, the walls of coal also began to make a cracking sound.
If once such phenomena happened, miners could not help but escape from their workings.
This painting shows a hewer and helper escaping from their coal face.
