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 …

Rock fragmentation is vital in a sublevel caving operation. The oversize fragments are the
most undesired fragmentation category because of their challenges; as such, they require …

Understanding the relations between drilling response parameters (drilling speed, axial
thrust force and torque, etc.) and rock properties is useful to quickly acquire lithology …

The use of UAV (unmanned aerial vehicle) platforms and photogrammetry in bathymetric
surveys has been established as a technological advancement that allows these activities to …

How to accurately measure and acquire lithology parameters is the key of drilling
exploration in geological engineering. In this present study, a small-scale drilling platform …
