| Abstract: | Summary. Discontinuous manual observations and irregular caving characteristics of roof rocks often lead to improper decisions resulting
in accidents and production loss. Hence, systematic monitoring of the hanging roof behind the chock shields is necessary for
safe and productive mining operations. A real-time application was successfully implemented in an Indian mine for forecasting
of hanging roof behaviour to enhance safety and productivity. This paper reports the functioning of real-time TWAP (time weighted
average pressure) analysis in the forecasting of hanging roof behaviour in real time. |
