During automatic and intelligent cutting at the coal mining face, complex geological
conditions (fold structure, fault structure and magmatic intrusion) easily cause distinct …

User's choices of conical picks currently involve specifying their material and geometric
parameters (functional requirements), incorporating the place and conditions of their work …

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 …

This paper presents information on the current most-widely-used cutting heads; ie,
tangential-rotary picks. It describes their applications, design, methods for improving their …

As part of own works performed by the Department of Machine Engineering and Transport of
AGH University of Science and Technology, investigations into the rate of conical picks' wear …

Abstract Since Small and Medium-sized Enterprises (SMEs) in iron and mining industries
are significant contributors not only for Gross Domestic Product (GDP) and labour creation of …

Shearers and roadheaders are commonly used to extract useful mineral deposits, especially
hard coal, and for drilling roadways in underground mines, tunnels and other underground …

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 …

In underground mining, shearers are mainly equipped with conical picks. Under difficult
working conditions and in the case of abrasive rocks mining, the durability of tools …
