Opencast mine are used when deposit of commercially useful ore or rocks are found near the surface. To create an openpit mine, the miners must determine information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting each hole location on map.

Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes.
mining pits, benches and making the opencast systems more sustainable and productive (Chatpole and Robins, 2013). A star schema modelled in Fig. 2, demonstrates the connectivity between open pit data dimensions and other associated attributes of the mining areas.
working benches of a typical coal mine is shown in Fig 1. Figure 1: Benches in a typical opencast mine Slope stability is a major problem in opencast mines. Slope stability in a large scale open pit mining operation is a matter of concern for the mine management
Several benches may be in operation simultaneously in different parts of, and at different elevations in the open pit mine. Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals.

Opencast mines are dug on benches, which describe vertical levels of the hole. The interval of the benches depends on the deposit being mined, the mineral being mined, and the size of the machinery that is being used. Generally, large mine benches are 12 to 15 metres thick.
Opencast mining is also known as openput mining, opencut mining, surface mining and also as strip mining, the later term being commonly used in the for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.
Mar 13, 2012 What is Opencast Mining Opencast mining is also known as Open pit mining, Open cut Mining, Surface or Strip Mining. The coal upto economical depth will be excavated by OC Method. The current operating depth of OC mines in SCCL is about 200m and SCCL proposed to operate OC mines upto a depth of 420m.
Opencast Mining is a Mining which open to sky. This mining is also called openpit, quarry, strip mining. This mining is much easier than Underground mining. It is involves in removing of the upper layer of alluvium or rocks or both to reach the Mineral bed. In this method the minerals are completely removed. Further it is done in the following
Limestone Mines Opencast. Limestone mining is being implemented by fully mechanized opencast mining methods in all the mines under the study. The working pit has been excavated by developing working benches of 910 m in height.
