Assessment of top coal fall potential is great importance for sustainable longwall caving mining. However, available assessment tools/indices the are applicable to roof rock only, and their use (whose geological structures may be different) can inappropriate. This paper presents a new index in mining where controlled by cantilever effect. The developed from an integrated numerical statistical a...

The present work focuses on the skew-symmetry index as a measure of social reciprocity. This index is based on the correspondence between the amount of behaviour that individuals address toward their partners and what they receive in return. Although the skew-symmetry index enables researchers to describe social groups, statistical inferential tests are required. This study proposes an overall ...
