Extensive investigation has been conducted to determine the causes of a series of roof falls occurring in an underground coal mine located in southern West Virginia. Underground observation, along with laboratory testings and finite element analyses, were conducted to search for possible mechanisms for the roof falls. Results of the investigation have led to a better understanding of the mechanisms involved in the roof falls. Necessary modifications of mine layout and roof support plan are proposed for improving safety and profitability at the mine.
