Increasing demand for the use of different mechanized excavation systems in civil and
mining projects has elevated the importance of understanding the wear process of rock …

The diverse nature of polymers with attractive properties has replaced the conventional
materials with polymeric composites. The present study was sought to evaluate the wear …

When shield TBM tunneling in abrasive sandy ground, excessive cutting tool wear resulting
from untimely and inaccurate failure evaluation is prone to damage cutterhead structure and …

Abrasiveness as an intrinsic property of rocks defines the extent of wear or loss when
interacting with other materials. In engineering sectors like hard rock mining and tunnelling …

The scraper conveyor is the key conveying equipment for fully mechanized coal mining.
Wear failure of the chute is the main form of failure of the scraper conveyor. In this study, the …

The Cerchar test method and its index, the so-called Cerchar abrasivity index, are most
commonly used to determine the abrasivity of rocks and other geo-materials for construction …

Wear occurs on mechanical tools during rock cutting and drilling, or any other kind of
mechanical based excavation of rocks. The determination of rock abrasivity plays therefore a …

Rock abrasivity influences wear of cutting tools and consequently, performance of
mechanized tunneling machines. Several methods have been proposed to evaluate rock …

The Cerchar test is the most commonly used method for evaluating rock abrasivity and
estimating tool wear. The conventional test results are reported based on the measured …

To see if and how abrasive potential as well as drilling efficiency change due to rock
heating, Cerchar scratch tests were performed on six types of rock at eight temperature …
