Abstract
Roof falls are a major hazard in underground mining. Roof bolting is the primary means of supporting the mine roof in underground coal mines. Despite great strides in the design of support systems, roof falls continue to occur in bolted areas. Noninjury roof fall reports provide insight into the characteristics of roof falls. This study examined 11,600 noninjury roof fall reports to identify geological contributors to roof falls. The goal is to provide data that can help improve roof-fall-related safety by providing direction for the research and development of improved support systems and mine layout alternatives.
