Apr 18, 2017· Good operating practice is key to reducing drill hole deviation. Every mining operation has had to deal with damaged drill rods or stalled operations due to hole deviation. While your choice of equipment can help, good operating practice is the most effective way to mitigate the problem.
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
Other articles where Stope is discussed: mining: Underground mining: .of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a perton basis than stoping, so that every effort.

Cutandfill stoping is applicable to the mining of firm ore enclosed within walls, one or both of which are weak and heavy. The deposits may be tabular in form, dipping at angles steeper than the angle of repose of the broken ore (or flatter, if scrapers are employed for moving the ore in the ore passes), or to wide, thick ore bodies or masses.
