... in an abandoned quarry at Acuto (central Italy) to realise a natural-scale test site for detecting rock-falls from a cliff slope. The installed multi-sensor monitoring system consists of: two weather stations; optical cam (Smart Camera) connected to an Artificial Intelligence (AI) system; stress- strain...

... Abstract A rock fall is significant phenomenon in rock engineering. happens quickly. In 2009, a rock fall occurred in a slope located above a concentration plant in the Sungun copper mine (northwest of Iran) and damaged structures. After the occurrence of the rock fall, both a stability...

... Abstract A debris flow is represented by a mixture of solid particles of various sizes and water, flowing along a laterally confined channel-shaped region whilst a rock fall is represented by singular rock blocks moving along the path with different kind of motion like sliding, rolling...

... a history of large rock mechanical problems. In the second half of 2007 and in the beginning of 2008 a number of seismically induced large rock falls took place. On the 2nd of February 2008 a large seismically induced rock fall took place causing a fatality. The mine has since then been regarded...

... on unstable blocks on the surface of jointed rock mass. This fact can be critical in cases such as Vall de Núria rack railway, where tunneling works are the main measure for rock fall risk mitigation, especially when the service must remain fully operational and safe during the excavation phase. Newmark...

... (involved volume in the range 10- 2 -10 2 m 3 ), mass falls (10 2 -105 m 3 ), very large mass falls (105- 107 m 3 ) and mass displacement (more than 107 m 3 ). We deal with rockfalls involving less than 105 m 3 , i.e. "fragmental rock falls" (Evans & Hungr 1993), characterised by negligible interaction...

... on a current rock classification system, would have resulted in shotcrete and comprehensive pattern bolting along approximately half of the tunnel stretch. However, the tunnel was completely unsupported, but still in good Condition with rock falls totalling less than 4 m 3 , most of which could be related...
