Surface mining Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Application of Data Mining Techniques to Healthcare Data

Data mining encompasses a wide variety of analytical techniques and methods, and data mining tools reflect this diversity. Many database vendors are moving away from providing stand-alone data mining workbenches toward embedding the mining algorithms directly in the database. This process is known as "in place data mining" and it

Mineral Extraction The Environmental Literacy Council

The three most common types of surface mining are open-pit mining, strip mining, and quarrying. Whether the surface is broken up by explosives, as is common in quarrying, strip and mountaintop mining, or by large pieces of equipment, common in open-pit mining, the principle remains the same—the overburden is excavated and moved elsewhere so that the mineral can be extracted.

Clustering in Data Mining Algorithms of Cluster Analysis

Nov 04, 2018That is according to house type, value, and geographic location. In this Data Mining Clustering method, a model is hypothesized for each cluster to find the best fit of data for a given model. Also, this method locates the clusters by clustering the density function. Thus, it reflects the spatial distribution of the data points.
