Open Pit Mining

Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8 ). Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when.

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.

Lecture 2: An introduction to mining

This lecture covers mining and introduces how mining generally is done, what machinery and methods are used and how ore and waste rock travel within the mine complex. Mining is done to liberate minerals from the crust of the earth. This is done in several steps. The steps differ between mines depending on commodity and factors such as composition.

 · 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.
