Abstract

It is considered that accumulation of the data related with horizontal traveling distance from the foot of a slope of fallen rocks is insufficient, although the data are basically important to determine the positions of concreate structures or net fences for the prevention of rock fall disasters in open pit mines and other places. Relation between kinetic energy of rock falls and the horizontal travelling distances has been given from video analyses on rock fall behaviors in a quarry. Then an evaluation method of the probability value of upper range of optional horizontal travelling disrance is proposed, in which the relations between kinetic energy, and mean value and standard deviation of the distribution of horizontal travelling distances are used.
