This mining method is useful because it allows for huge volumes of material to be mined at relatively low costs, which makes lower grade deposits economical to turn into mines or new pits. Many large-scale open-pit operations have plans to progress into block caving operations over time, including Oyu Tolgoi and Grasberg.

Dec 12, 2018018332Mining techniques can be divided into two broad categories surface mining and subsurface mining See Figure 1. Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities. Conversely, subsurface mining involves sinking a mineshaft and digging tunnels to reach a.

Longwall Mining Longwall mining involves using a mechanical shearer to extract coal from long rectangular blocks of medium to thick seams. Ultimate seam recovery using longwall mining techniques can exceed 75. In longwall mining, continuous miners are used to develop access to these long rectangular coal blocks. Hydraulically powered supports temporarily hold up the roof.

Mining techniques. Surface mining. Surface mining is done by removing stripping surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits. Techniques of surface mining include open-pit mining, which is the recovery of materials from an open pit in the ground, quarrying, identical to open-pit mining.

Data mining is the process of finding anomalies, patterns and correlations within large data sets involving methods at the intersection of machine learning, statistics, and database systems. Since data mining is about finding patterns, the exponential growth of data in the present era is both a boon and a nightmare.

Dec 12, 2018018332Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs. If there is enough ore, initial capital will be recouped over the life of the deposit.
