A coal bump or burst is defined as the instantaneous violent failure of a coal pillar from overstress. The causes of coal bumps are not well understood, although minor disturbances are a daily occurrence in bump prone seams. Lack of knowledge about coal bumps coupled with questionable mining practices can create disastrous consequences. This paper describes different coal bumps, discusses accidents caused by coal bumps, and presents preventive measures.
