From the past few decades many nature inspired algorithms have been developed and
gaining more popularity because of their effectiveness in solving problems of distinct …

The technological difficulties related with blasting operations have become increasingly
significant. It is crucial to give due consideration to the evaluation of rock fragmentation and …

In this study, we propose a new hybrid algorithm fusing the exploitation ability of the particle
swarm optimization (PSO) with the exploration ability of the grey wolf optimizer (GWO). Our …

The potential surface settlement, especially in urban areas, is one of the most hazardous
factors in subway and other infrastructure tunnel excavations. Therefore, accurate prediction …

Backbreak is a rock fracture problem that exceeds the limits of the last row of holes in an
explosion operation. Excessive backbreak increases operational costs and also poses a …

Backbreak (BB) is one of the serious adverse blasting consequences in open-pit mines,
because it frequently reduces economic benefits and seriously affects the safety of mines …

Drilling and blasting is a widely-used method for rock fragmentation in open-pit mines,
tunneling and civil projects. Flyrock, as one of the most dangerous effects induced by …

Deep underground excavations in mining and civil engineering are subjected to high in-situ
stresses which can cause rockburst. Rockburst is an instantaneous release of a large …

Blasting operation is an inseparable operation of the rock fragmentation process in the
surface mines and tunneling projects. Ground vibration is one of the most undesirable …

In this study, vibration sensors were used to measure blast-induced ground vibration (PPV).
Different evolutionary algorithms were assessed for predicting PPV, including the particle …
