DSS developers sometimes incorporate results from data mining into operational decision support systems (DSS). The data mining process involves identifying an appropriate data set to "mine" or sift through to discover data content relationships.
A critical safety component for all underground mining is intrinsic and standing support systems. Specifically, tabular hardrock mining exploits a wide variety of deposits that require various methodologies to safely mine the ore
Data mining tasks are used to extract patterns from large data sets. The various data mining tasks can be broadly divided into five categories as summarized in Fig. 1.The taxonomy reflects the emerging role of data visualization as a separate data mining task, even as it is used to support other data mining tasks.
