A coal mine bump is a sudden, violent failure of a coal pillar or group of pillars which occurs primarily due to excess stress buildups during pillar retreat operations and longwall mining. The intensity of bumps range from minor thumping of coal pillars to large quantities of coal suddenly ejected into the mine workings where men and machinery are present. Some of the larger bumps have displaced entire coal pillars into mine entries. Others have sent shock waves throughout entire mining sections, some being felt hundreds of feet away on the surface. During 1983 there were three fatalities in southern West Virginia attributed to mountain bumps. These fatalities, coupled with a general lack of understanding of the factors which trigger bumps, prompted an industry sponsored workshop to be held to discuss relevant experiences, and to formulate a plan of action. This workshop was held in Princeton, West Virginia on March 7 and 8, 1984. This paper will review the results of that workshop and summarize the research being conducted by the Bureau of Mines to address the needs expressed by the workshop participants.
