Mining The process of taking out minerals buried under the rocks is called mining. There are two main methods of mining, viz. open-cast mining and shaft mining. Open Cast Mining When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process. The Data Mining types can be divided into two basic parts that are as follows Predictive Data Mining Analysis. Descriptive Data Mining Analysis. 1. Predictive Data Mining. As the name signifies, Predictive Data-Mining analysis works on the data that may help to know what may happen later (or in the future) in business.

Types of Mining ADVERTISEMENTS There are basically two types of mining (i) Surface mining In this type of mining the minerals or rocks that are to be mined are exposed at the surface or very close to the surface. To extract the materials, earlier the miners used to dig an open-pit on the surface and then dig out the materials. There are two types of mining laser and core, and four types of rings metallic, metal-rich, icy and rocky. For laser mining. The biggest yield increase is given by mining in a hotspot of the mineral you want to mine. Overlapping hotspots are no longer believed to have any advantage compared to single hotspots.

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling. Apr 30, 2020 4. Other types of data. We have a lot of other types of data as well that are known for their structure, semantic meanings, and versatility. They are used in a lot of applications.

Feb 02, 2018 Data mining is a diverse set of techniques for discovering patterns or knowledge in data.This usually starts with a hypothesis that is given as input to data mining tools that use statistics to discover patterns in data.Such tools typically visualize results with an interface for exploring further. The following are illustrative examples of data mining. Mining Various Kinds of Association Rules . 1. Mining Multilevel Association Rules. For many applications, it is difficult to find strong associations among data items at low or primitive levels of abstraction due to the sparsity of data at those levels. Strong associations discovered at high levels of abstraction may represent commonsense knowledge.
