Open flames were used to help miners see until the advent of portable lighting. There was a massive amount of dust flying around coal mines, and it is very flammable. When it's a fine powder, it becomes explosive. The reason charcoal does not do this with a grill is because charcoal is made from wood products, not coal, and is not nearly as flammable or capable of producing the fine particulate dust that can combust easily.

It is a question of the fuel oxygen ratio. Coal dust has a very high mix rate and as such will burn so quickly it is a form of explosion. A briquet has a very low surface area and is not as volatile. Note that any dust will explode. Flour has always been dangerous and grain silos are built to contain massive explosions.
