Map Info & Chart : Help reading a coal mine map

Hi

I am playing with hobby video game project. Nothing fancy, commercial, political, ambitious etc. and was looking at some coal mine maps of some abandoned coal mines in US/Eastern Ohio/Perry County

I am not familiar with coal mines, but am I right if I read the large dotted lines on the map as tunnels (see red/marked example on the image)?

And the many thin lines as just scribbles pointing to rock/limestone etc.?

Thank you in advance and let me know if this question belongs to another sub
