Bump hazard criteria derived from basic geologic data.

The U.S. Bureau of Mines is conducting research to develop a quantitative means of assessing bump-prone geologic conditions using lithologic and topographic information. An engineering software package that includes a spatial relational database, data modeling, and graphic data display is used to apply a set of geologic criteria to assess bump-proneness and produce hazard maps. This paper presents the method and criteria developed through case studies of mine properties in the Pocahontas No. 4 coalbed in southern West Virginia and the Pocahontas No. 3 coalbed in western Virginia. Initial results suggest general agreement between the hazard map and field observations. Further development of the criteria and parameter identification are ongoing.
