Hard Rock Miner''s Handbook is a work of the heart. Jack—whose 40+ year career spanned engineering, construction, and operation of mining projects worldwide—conceived of and wrote the first edition of the Handbook, published in June 2000, to assist miners and engineers in the difficult world of hard rock mining. It was his
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
In this month''s Spotlight Feature Article, from the pages of the June 2012 issues of International Mining, Editor Paul Moore reports that Underground Drilling remains a challenging environment, so continued improvements from key machine and component suppliers continues to help mines improve efficiency, particularly as operations go deeper.

Long hole stoping. Long hole stoping as the name suggests uses holes drilled by a production drill to a predetermined pattern as designed by a Mining Engineer. Long hole stoping is a highly selective and productive method of mining and can cater for varying ore thicknesses and dips (0 90 degree).

Mining Stope Development Method. Shrinkage stoping is a shorthole mining method which is suitable for steeply dipping orebodies. This method is similar to cut and fill mining with the exception that after being blasted, broken ore is left in the stope where it is used to support the surrounding rock and as a platform from which to work.
Soil sampling and geophysics 1 is applied by the mining company''s geologist in order to detect the presence and position of an ore body ( an anomaly).When an anomaly is found, the mining company will initiate a drilling program in order to test the extent of the mineralization.

Fill of one form or another has been used more or less throughout the history of mining. It is used to fill underground voids where the ore has been extracted, either to provide a working platform from which the next slice of or can be extracted, ...
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.

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.
