Abstract
NIOSH research in underground stone mines has provided the framework for developing a Roof Fall Risk Index (RFRI). This method is centered on examining the defects contained in the roof caused by a wide range of local geologic, mining, and stress factors. The RFRI is based on observations and should be considered part of an overall strategy deployed by mining operations to assess the risk of roof falls. Clearly more information leads to less uncertainty and potentially reduces the risk associated with ever-changing mining conditions. NIOSH's aim is to develop a method to help mine safety personnel identify and track changing roof conditions. The RFRI is an assessment technique that can be used to rate roof fall risk in important parts of a mine or potentially the entire mine property. It should also be viewed as a powerful communication tool that helps to track changes in roof conditions. In addition, it can be used as a training method to help less experienced miners identify defective rock conditions. Lastly, decision-makers can use the RFRI to examine changes in mining conditions and to help develop plans for proactive actions during the course of mine development.
