I asked him who made the map and how often it was updated. The Chief took pride in telling me that it was he who had drawn the map, and that he updated it once a year, between Christmas and New Year's Eve. I informed him that, at the last mine I visited, the map was generated and kept up to date every week by a computer.
The Chief thought about this for a while then told me he didn't think that was really necessary for his mine. As I walked out of his office, I asked myself how would anyone know where to rescue people in case of an accident. It occurred to me that they probably wouldn't know where to look.
A few years later, I heard on the News that five miners were trapped in a gallery, inside this very mine. I could picture the Chief struggling to identify their location on the Christmas tree.
Apparently, the roof of a gallery had collapsed because the structural data supplied by the Engineer was inaccurate. Nobody blamed the Chief for the death of the five miners. But he did. He went insane with guilt, and was committed to a psychiatric hospital. The Director of the mine died of a heart attack, within the end of that year. It was a tragedy."
