Where are the coal versions of Fukushima and Chernobyle? Surely you can point to tens of examples easily as coal has been in use much longer and on a larger scale.
Why yes, one can -- of course, the exact examples you are looking for depend on what aspects of "Fukushima and Chernobyle" you are asking for coal-mining versions of.
Are you asking about examples of sudden, unexpected disasters causing mass death or destruction of nearby cities? Okay, here are some:
Ok Tedi disaster
Buffalo Creek Flood
Or perhaps you are asking about situations in which large numbers of industry workers were killed in an accident? Yep, we've got those too... thousands of coal workers die from accidents every year.
Or maybe you're wondering about if there are entire regions whose ecosystem has been destroyed by coal? Yes, there are.
Or perhaps you are asking about the slow-motion health and environmental damage caused by coal even when everything is working as designed? Yup, there's that as well.
Nuclear certainly has its problems, but coal is much, much, much worse.
