Rock fragmentation by blasting is still among the most challenging of problems in
geomechanical engineering. The intent of this work is not to develop a new overall blast …

The assessment of overbreak is proposed by means of a novel empirical approach; the
'overbreak resistance factor'(ORF), to predict and manage the overbreak phenomenon in …

Shear strength of rock masses is critical for geotechnical tasks including tunnel, slope
stability, and foundations. Various approaches comprising of back calculation, large-scale …

In geotechnical engineering, excavation process is affected by many factors, so that the
evaluation of the excavatability is a difficult task in the field. In order to have a better …

Rock mass classification systems have been developed in various applications of rock
engineering design such as tunnelling, foundation, slopes, rippability, and excavatability …

Blastability is defined as the resistance of rock mass to fragmentation due to the dynamic
stress of blasting. Comprehensive study and understanding of geomechanical conditions of …

The unexpected effect of a distant earthquake is studied in this paper, which caused a
landslide at the eastern part of the hotel" Atrium" in Thassos Island, Northern Aegean Sea in …

The significance of this paper is the evaluation of the use of BQS (blastability quality system)
on rock slopes in practice A landslide, which took place in Northern Greece, in a tectonic …

Choosing the optimal pattern for blasting and pyrotechnics in a tunnel is a challenging
engineering problem considering the available methods. The most important methods for …

Blasting produces energy to fragment the rock mass in mining, quarry and civil engineering
projects. In mining and quarrying operation, blasting aims to extract the largest possible …
