Mining Method Selection - Edumine Online Tool

    Notes on Mining Method Selection. UBC Mining Method Selection is a modified version of the Nicholas approach for selection of mining method based on orebody characteristice (refer Nicholas 1981). Selection involves summation and ranking of numerical values associated with orebody characteristics that reflect the suitability of a particular method.

    Mining Funda: Cut and Fill Stoping

    Cut and fill stoping is a method of underground mining used in vertical stopes and in mining high-grade irregular ore bodies. The rock mass surrounding the ore deposit is also usually weak unable to support loads over an extended stoping height.

    Shrinkage stoping is rather hard to mechanize; in addition, an important period may elapse amid the commencements of mining in the stope and the last withdrawal of all the broken ore. The solitary principal basis of tantalum mineral concentrates is the manufacture by Sons of Gwalia Ltd. from its Greenbushes and Wodgina mines in Western Australia.

    Underground Mining Methods – EXCELLENCE IN MINING ...

    Jul 21, 2016 · Underground mining is the process of extracting minerals and ores that are located too far underground to be mined efficiently using surface mining methods. The primary objective of underground mining is to extract ore safely and economically while minimizing handling of waste rock. Typically, underground mine has less environmental impact.

    stoping mining method : definition of stoping mining ...

    Stoping is the removal of the wanted ore from an underground mine leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to cave into the stope, although in most cases artificial support is also provided. As mining progresses the stope is often backfilled with tailings, or when needed for strength, a mixture of this material and cement.
