Mine safety in coal mines, which in turn can initiate more extensive coal dust explosions. For this reason, rock dusts such as limestone dust are spread throughout coal mines to diminish the chances of coal dust explosions as well as to limit the extent of potential explosions, in a process known as rock dusting.

For this reason, water is often used to cool rock-cutting sites. Miners utilize equipment strong enough to break through extremely hard
