Robust Design of Pillar Arrangement for Safe Room-and

Oct 27, 2021 · The arrangement of pillars is a key design parameter in the execution of the room-and-pillar mining method. The objective of this study is to provide safe, reliable and a robust design for pillar arrangements for economic and efficient mineral recovery. Four design parameters have been considered in this study, including the degree of pillar superposition, pillar stiffness, and the pillar

Highwall concernsPit & Quarry

Jun 09, 2021 · Technologies such as remote sensing should not replace basic geotechnical methods of investigation, but should be used in combination with tried-and-true methods. An active attention to early warning signs from highwalls such as tension cracks, loose material or abnormal water flow can signal a greater geohazard event is imminent.
