Question

why do we have to mine the coal from underground to get it??​

Answer 1

The primary purpose of underground-mine ventilation is to provide oxygen to the miners and to dilute, render harmless, and carry away dangerous accumulations of gases and dust. In some of the gassiest mines, more than six tons of air are circulated through the mine for every ton of coal mined.

Hope it helps ..
