Under the British Raj a committee of experts formed in 1894 formulated regulations for mining safety and ensured regulated mining in India. The committee also passed the 1st Mines act of 1901 which led to a substantial drop in mining-related accidents. The accidents in mining are caused both by man-made and natural phenomenon, for example, explosions and flooding. The main causes for incidents resulting in serious injury or death are roof fall, methane gas explosion, coal dust explosion, carbon monoxide poisoning, vehicular accidents, falling/slipping and hauling related incidents.
