 · Some variations of the room-and-pillar mining method include post room-and-pillar mining and step room-and-pillar mining. Post room-and-pillar mining is a combination of room-and-pillar mining and cut-and-fill stoping mining, whereas step room-and-pillar mining is a variation of room-and-pillar mining in which the footwall of an inclined ore body is adapted for use of trackless equipment.

Various Methods In Classification

Classification is a data mining technique that predicts categorical class labels while prediction models continuous-valued functions. For example, a classification model may be built to categorize credit card transactions as either real or fake, while the prediction model may be built to predict the expenditures of potential customers on furniture equipment given their income and occupation.
