[ 1 ] - Investigating the Relationship between Various Brittleness Indexes with Specific Ampere Draw in Rock Sawing Process
This study aimed to develop new statistical models for evaluating the specific ampere draw (SI) based on rock brittleness index in rock sawing process. A variety of rocks, including carbonate and granite, were cut by a fully instrumented laboratory-sawing rig with two different types of circular diamond saws. Laboratory tests were performed at different depths of cut and feed rates. Multiple cu...
[ 2 ] - A Numerical Analysis on the Performance of Counterweight Balance on the Stability of Undercut Slopes
One of the important parameters in undercut slopes design is the determination of the maximum stable undercut span. The maximum stable undercut span is a function of slope geometry, the strength parameters of the slope material, condition of discontinuities, underground water condition, etc. However, the desired production capacity and therefore the size of excavating equipment will sometimes a...
