apr 15, 2019 there are two basic steps to gold mining: prospecting and production. prospecting refers to the actual search in a certain area for valuable minerals, and production, also known as mining, is the physical act of removing the gold from where you found it.since different equipment exists for prospecting and mining, this article explores, briefly, equipment used for prospecting, and then the typical large open pit mining operation that has been in production for years and more is operating under conditions that could not possibly have been foreseen by the orig inal planners of nov 29, 2011 So the open-pit mines have tended to get more productive, but at the underground mines, where you have a bunch of workers, they all go underground in a cage, they all go off to their working places, its very difficult to monitor what everyone is doing assessing and monitoring open pit mine highwalls jami girar, p.e c.m.s.p. ining engineer, national institute for occupational safety & health, spokane research laboratory, 315 montgomery ave spokane, WA 99207 introduction slope stability accidents are one of the leading causes of fatalities at u.s. surface mining operations.
