Abstract

In underground coal mines, we leave some coal in the form of "pillars" to support the roof andprevent the mine from collapsing. If these pillars are too small, the roof can fall and causeaccidents. If they are too big, we lose valuable coal. So, designing the right size and shape of pillars is very important.
