SOLUTION: Explosive devices used in mining

Explosive devices used in mining operations produce (nearly) circular craters when detonated. Suppose that the radius of a crater, denoted by X (in the unit of meters), resulting from a detonation of such explosive device follows an exponential distribution with ? = 0.10 meters. That is, the expected value of the radius is 10(= 1/?) meters. (a) Find the probability that a single detonation ...

Salt Mining HowStuffWorks

In solution mining, wells are erected over salt beds or domes (deposits of salt forced up out of the earth by tectonic pressure) and water is injected to dissolve the salt. Then the salt solution, or brine, is pumped out and taken to a plant for evaporation. At the plant, the brine is treated to remove minerals and pumped into vacuum pans, sealed containers in which the brine is boiled and ...
