Anti-tank mines are very similar to their anti-personnel cousins, but are much larger. These mines are pressure activated, but are typically designed so that the footstep of a person won't detonate them. Most anti vehicle mines require an applied pressure of 348.33 pounds (158 kg) to 745.16 pounds (338 kg) in order to detonate.

Grau (2002) reported that the estimated air quantity required for the equipment currently operating in an underground stone mine producing 113 million metric tons (1.25 million tons) is 401 m3/s (850,000 cfm) to dilute to a 400 tc :g/m3 concentration and 990 m3/s (2,100,000 cfm) to dilute to a 160 :g/m3 concentration. These conclusions.

Two main changes have occurred in open-pit mining technology over the past 100 years. The most obvious has been the increase in the scale of operations as higher capacity equipment has been developed. For instance, in the 1920s, a mining shovel with a 5 m 3 bucket was exceptional. Today, large open-pits use rope shovels or …
