This paper aims to discuss the recent development in rock hardness testing methods and
their applications in rock engineering and geological studies. Hardness is one of the …

This study is an attempt for comprehensive, combining experimental data with advanced
analytical techniques and machine learning for a thorough understanding of the factors …

Diamond circular sawblade has been widely used in hard granite processing. In this study,
the wear mechanism and wear evolution of the diamond segment were investigated. The …

The wear evolution indicated that abrasive wear is the dominant wear mechanism for disc
cutter wear. Considering the uneven rolling force distribution on the cutterhead, the relative …

Rock penetration is the most important function of tunnel boring machines (TBMs). Based on
a detailed review of TBM rock penetration research, this study introduces a rarely reported …

The Cerchar abrasivity index (CAI) is one of the most widely known index method for
identification of rock abrasivity. It is a simple and fast testing method providing reliable …

It is well-known that the indentation hardness property is influenced by micro-fabric
characteristics. The effect of textural characteristics on Vickers indentation hardness is …

The drilling rate index (DRI) is an important parameter that influences the drillability of rocks.
It can easily be used when estimating the economics of any excavation operation. Therefore …

The rock breaking mechanism plays a significant role in TBM (tunnel boring machine)
performance prediction, which has not yet been understood satisfactorily. In this work, a …

An experimental study was carried out to determine the influence of rock properties on
segment wear during the cutting of granite using an innovative diamond frame saw …
