When it comes to mining coal, an explosive gas known as methane will always pose a risk. When an area is opened up to mining, methane leaks out from the coal. This creates a threat to the miners if the gas gets ignited. However, there are steps that are taken to lessen the risk such as, pumping in fresh air to push the methane out. One major concern though is that people often take shortcuts that undermine safety. Sometimes such shortcuts result in a deadly explosion.
