Coal mining Underground, Surface, & Drilling Britannica
Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner’s progress.Open cast mining or surface mining deals with unconstrained operations and open to sky. Mining in India is a major economic activity and contributes up to 10 to 11% of GDP of total industrial sector.

An Investigation into Statistical Correlations Between Coal
In India, demand for coal exceeds its countrywide supply, despite its natural abundance, due to failure to achieve high production targets, especially in opencast mines, which are responsible for 94.98% of total raw coal production within the country. Employment of technological solutions, such as surface miners, is key to achieving In India, open cast coal mining is most dominant mining practice. While underground mining is unsafe for various occupational hazards, open cast mining, which extends to a large tract of exposed surface, is more hazardous, in terms of air pollution, water pollution, soil degradation, etc. (Ghosh & Majee, 2001 ; Ghose & Banerjee, 1995 ; Ambient Air Pollution and Respiratory Illness: A Study in Opencast Coal
