— Opencast coal mining generates a large amount of mine overburden spoils and creates huge overburden dumps in and around the mining area. It is a big issue as most of the overburden materials (OBMs) are unsuitable for vegetation due to lack of true soil characteristics, and are generally contaminated with toxic heavy metals (TMs).

Mining and Mineral Processing 3.1 Opencast Mines Opencast mining is extraction of commercial minerals from the Earth's surface using open-pit workings. About 60 % of metallic ores, 85 % of non-metallic ores, 100 % of non-metallics, and 35 % of coal are produced by this method. The distribution of mineral resources of the world is shown in …

Opencast mining is the oldest method of excavating minerals but the mining operations have been mechanised by the use of heavy earth moving machinery during the last 50 years resulting in excavations on a scale which was unthinkable half a century ago. Equipment # 1. Bulldozer: A bulldozer is often referred to simply as a dozer.

 — In fact, opencast mining is the most directly disturbed way which deteriorate land ecosystem in nature (Guan et al., 2017, Bruno Rocha Martins et al., 2020). Therefore, it is crucial to keep an eye on and conduct study on how opencast mining is affecting the quality of the ecology. The Muli coalfield has a 3.54-billion-ton coal reserve.

 — Coal is one of the most essential resources of a country. It is widely used for power generation and as a raw material in the industries. India ranks third in coal production. However, the country has to import …

 — Mine project planning is beset with various anomalies of geological reserves, quality of coal or mineral, availability of infrastructure, types of technology, methods of works, acquirable surface ...

 — Due to the depletion of coal reserves, the pillars and remnant coal are now removed using opencast mining rather than underground methods. However, the secondary extraction of pillars and remnant coal from the old workings using opencast methods entails some serious challenges that have a negative impact on the safety and …

 — In India, around 92% of the coal is produced by opencast mining method (Table 1). If do mestic coa l pro duction cont inues at 5% increasing rate, the extractable r eserve will last .

 — In India, around 92% of the coal is produced by opencast mining method (Table 1). If domestic coal production continues at 5% increasing rate, the extractable reserve will last for 45 years.

 — Opencast coal mining methods play a key role in enhancing coal production level which in turn fulfils growth necessities of the country. In case of opencast coal mining, the first step is to remove the overburden economically to expose the underlying coal for excavation and later on needs to be handled safely.
