Highwall Safety. Highwall stability is essential for open-cut mining. In these particular projects, otherwise known as open-pit mining, employs a technique in which rock and minerals are extracted from a borrow pit, or sandbox. For long-term highwall performance, the substance properties that makeup mining sites—or more specifically, the ...

Around 70% of the country's coal reserves are amenable to UG mining, which delivers several advantages. In FY22, out of 622.6 million tonnes of coal mined, nearly 96%, or 597 million tonnes, was opencast (OC) coal. India accounts for 12.5% of global coal consumption. Close to 70% of the country's electricity generation is coal-based.
