Underground Mining Methods and Equipment

and broken ore stored within the stope may f unction as a working platform and temporary wall supports. It was quite attractive in the period before mechanization became widespread, when smallscale operations on veintype deposits prevailed. However, with rising costs, the scarcity of skilled labor and the trend toward mechanization, the method has been largely displaced by sublevel stoping ...

Scalaz: Type classes

Type classes. A type class is a type system construct that supports ad hoc polymorphism. This is achieved by adding constraints to type variables in parametrically polymorphic types. Type class instances allow us to add behaviour to types without changing the types themselves. Type classes in Scalaz. Here is an overview of some of the type class hierarchy present in Scalaz. ore ...

Innovations: Introduction to Copper: Mining Extraction

Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and ...

Leaching | Article about leaching by The Free Dictionary

Leaching is done from piles of poor ore (compact leaching) or directly from the ore (if it is porous or cracked). In order to create a sufficient number of cracks in the ore, it is loosened by explosions using ordinary explosives or atomic charges (underground leaching). In these cases the solutions are supplied to the ore from above; the enriched solutions (which have soaked through the ore ...
