Purpose. This article proposes to analyze and determine the mining design for shallow-dip
deposits hosted in poor quality rock. Methods. We used the UBC tool to find the optimal …

The decision to exploit a mineral deposit that can be extracted by open pit and/or
underground mining involves consideration of the following options:(a) independent open …

In underground mines, sublevel stoping is used among a variety of different methods for
mining an orebody, which creates large underground openings. In this case, the stability of …

Spontaneous combustion of coal is a problem that affects the mining operation and
generates environmental, economic, social and geotechnical impacts. This phenomenon …

To investigate the reasonable roof-contacted filling rate (RCFR) of the backfill in the goaf of a
deep mine, the three-hinged arch mechanics model was applied to the two-step mine, and …

Cable bolts are one of the most common tension anchorage systems for reinforcing the
stability of rock/soil masses; however, the quantitative assessment of cable bolt safety via …

Abstract Purpose. The Bou Azzer Mine encounters difficulties during cobalt mining. In order
to select the optimal mining sequence with the least geotechnical stability problems, one …

The transition from surface mining to underground is a critical issue for metal mines. The
commonly cited procedure cored by ultimate‐pit‐limit (UPL) methodology is restricted to …

In the mine exploitation stage; one of the critical issues is the stability assessment of post-
pillars. The instability of post-pillars leads to serious safety hazards in mining operations …

Monitoring and providing warnings for coal mine rockburst disasters is a worldwide problem.
Several rockburst accidents have occurred in a 1301 belt transport chute near a 1300 fully …
