Mechanical mining is a widely used method of separating materials from the face to obtain a
useful mineral (eg, coal, metal ores, salts, and diamonds), to make underground workings …

Wear of the working surfaces of machinery parts is a phenomenon that cannot be fully
countered, only postponed. Among surface lifecycle elongation techniques, hardfacing is …

In this paper, the smooth finite element methods (S-FEMs) for accurate and reliable dynamic
analysis are proposed to improve the wear resistance of road header picks. Experimentally …

The rapid wear of conical picks used in rock cutting heads in the mining industry has a
significant economic impact in cost effectiveness for a given mineral extraction business …

Hardfacing is one of the techniques used for part lifecycle elongation. Despite being used for
over 100 years, there still is much to discover, as modern metallurgy provides more and …

The wearing of cutting tools is a bottleneck of many branches in the industry. However, the
tools used in the mining sector are extraordinarily prone to rapid deterioration since many …

In this study hardfacing by flux-cored arc welding with Fe-Mo-Mn-BC-based alloy as an
alternative technique for improving wear resistance of mining machines conical picks was …

Hardfacing is one of the techniques used for part lifecycle elongation. Despite being used for

In the mining and construction industries, hand drills are used to carry out many processes
related to excavation and auxiliary works. Hand drilling is commonly applied for making …

In this study, a field test was conducted to determine the effect of reinforcement around the
insert on the wear damage of the pickcutter. Prior to the field test, a linear cutting test was …
