Illegal mining was the most common way of mining coal in Ukraine, and probably was the main reason behind strife there. So illegal mining boom which is a lot more hazardous and a lot more dangerous for miners is very likely if normal one is banned. You don't solve these problems as easily. To really fix it, a way to produce minerals in economically safe and preferably, sustainable way (like, filtering out of ocean water) is needed.
