if i am not wrong , its the question in the sst book of class 10th
rat hole mining is a term used in coal mining and is so named because of its name during colonial times, the sistema del rato, and because of the sizes of the holes. ... The mining is done by digging small holes into the ground, much like the holes dug by rats.
