Mining is the most dangerous job because the mines are often located in high depth when accidents (explosions or cave) it is difficult to save up. The deep mining (especially coal mines) are often explosive methane gas buildup is dangerous just a small spark can trigger an explosion causing more or less collapsed tunnel. This gas would otherwise explode special accumulates causing lack of oxygen to the miners. When the tunnel collapsed for many reasons, and the miners are not crushed but luckily trapped will be able to survive very little due to lack of oxygen, water and food to hold out before the rescue team to get where miners. Often the modern mining regulations must have exits to the miners when the event but sometimes the mines absolutely no way out of this.
