INTRODUCTION TO MINING MINING''S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind''s earliest endeavors— granted that agriculture was the first. The two industries ranked together as the primary or basic industries of early civilization. Little has changed in the
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.
Actual capital expenditure for boring per metre of shaft by the technique of shaft boring is higher than by the conventional drilling blastingmucking method and other special methods of sinking. But the cost is likely to be reduced with more knowledge of the ''knowhow'' in handling of rigs. Such machines are not used in Indian mining practice.

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.

The focus of data mining is to find the information that is hidden and unexpected. Data mining can provide huge paybacks for companies who have made a significant investment in data warehousing. Although data mining is still a relatively new technology, it is already used in a number of industries.
Biomining provides a novel solution to complex environmental issues. Additional capabilities include the bioleaching of metals from sulfide ores, phosphate ores, and concentrating of metals from solution. One project recently under investigation is the use of biological methods for the reduction of sulfur in coalcleaning applications.

LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.

Data mining, in contrast, is data driven in the sense that patterns are automatically extracted from data. The goal of this tutorial is to provide an introduction to data mining techniques. The focus will be on methods appropriate for mining massive datasets using techniques from scalable and high performance computing.
