Final Answer:
1. A mine is a hole in the earth where people dig for rocks like coal; miners work in mines, sometimes in deep underground tunnels.
2. In the past, miners worked by hand in the dark for many hours, using hand tools to dig out coal.
3. The safety rules are: Rule 1 — Miners must be able to breathe fresh air; Rule 2 — Strong beams hold up the mine roof so it won’t fall on them.
4. The modern tool of mining is machines (like big scooping machines).
5. After the coal is cut, it is taken out of the mine—first soil is removed, then big machines scoop the coal out; a moving belt carries it away.
6. At the power station, crushed coal is burned to heat water and make steam; the steam turns a generator, which makes electricity.
