Can you survive a fallout?

Nuclear bombs are extremely deadly weapons, but their worst effects are confined to a limited zone. A government safety expert says it’s entirely possible to survive a nuclear explosion and its aftereffects.

How many miles away from a nuclear bomb is safe?

Those closest to the bomb would face death, while anyone up to 5 miles away could suffer third-degree burns. People up to 53 miles away could experience temporary blindness. But a longer-term threat would come in the minutes and hours after that explosion.

Does the UK still mine coal?

The last deep coal mine in the UK closed on 18 December 2015. Twenty-six open cast mines still remained in operation at the end of 2015. In 2020 Whitehaven coal mine became the first approved new deep coal mine in the United Kingdom in 30 years.

Why are deep mines hot?

Deep underground mines are “hot” work sites because of the heat from the rock itself. Ground water flowing through hot rock formations becomes hot and adds to the air temperature. Activities like drilling, blasting, and welding add to the heat load put on miners, on the surface and underground.

Are coal mines hot or cold?

The walls of a coal mine aren’t black—they’re white, covered with many layers of crushed powdered limestone called rock dust, required by law to suppress the omnipresent coal dust. The mine is a very cold, wet and dark place. Ground water leaks through the rock, and pumps run continually to remove the water.

Why do coal miners dust the walls?

Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.

Where is coal found in the ground?

Coal exists in underground formations called “coal seams” or “coal beds.” A coal seam can be as thick as 30 meters (90 feet) and stretch 1,500 kilometers (920 miles). Coal seams exist on every continent. The largest coal reserves are in the United States, Russia, China, Australia, and India.

What is the overburden?

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is removed during surface mining, but is typically not contaminated with toxic components.
