    Cut and fill mining is a method of short-hole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of long-hole methods. The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings. Either fill option may be cemented with binders to add ...

    The ore deposit type is Polymetallic veins of hydrothermal origin. The mining method used is underhand cut and fill mining. [3] The mine's primary access and production are through the Silver Shaft, an 18-foot (5.5 m) diameter, concrete-lined shaft sunk to a depth of 6,200 feet (1,890 m), [4] [5] [6] over 2,800 feet (855 m) below sea level.

  5. Stoping - Wikipedia

    en.wikipedia.org/wiki/Stoping

    In shrinkage stoping, mining proceeds from the bottom upwards, in horizontal slices (similar to cut and fill mining), with the broken ore being left in place for miners to work from. Because blasted rock takes up a greater volume than in situ rock (due to swell factor ), some of the blasted ore (approximately 40%) must be removed to provide ...

    With new-style classes, objects and types were unified, allowing the subclassing of types. Even entirely new types can be defined, complete with custom behavior for infix operators. This allows for many radical things to be done syntactically within Python. A new method resolution order for multiple inheritance was also adopted with Python 2.3 ...
