The discrete element method (DEM) is used to model granular materials and analyse a wide
range of related applications. However, accurate predictions can only be made if the input …

The technology of drilling tests makes it possible to obtain the strength parameter of rock
accurately in situ. In this paper, a new rock cutting analysis model that considers the …

The reasonable design and in-time optimisation of the supporting scheme is very important
for ensuring the safe control of the surrounding rock. The key steps are to conduct in-situ real …

This paper presents advanced computer simulation of rock cutting process typical for
excavation works in civil engineering. Theoretical formulation of the hybrid discrete/finite …

The cutters on the cutterhead of a tunnel boring machine (TBM) are usually divided into
center cutters, face cutters, and gage cutters, and have significantly different force …

Problems concerning the influence of the geometric parameters of an undercutting anchor
on the range of the failure zone of rock medium during the pulling out of the anchor …

High geostress is a prominent condition in deep excavations and affects the cuttability of
deep hard rock. This study aims to determine the influence of confining stress on hard rock …

For severe wear of a conical pick on tunneling and mining equipment, the influence of pick
cutting types, structure and working angle parameters on pick wear is studied using an …

In this paper, the response characteristics of parameters along the borehole while drilling to
rock mass interface are experimentally studied by drilling method. Using the developed …

A conical pick is an essential cutting tool used particularly on mining excavators. The cutting
performance and wear of the pick directly affect the efficiency and cost of the rock/mine …
