In this paper, stope structure optimization during sublevel caving mining is considered under
the condition that the isolated draw zones (IDZs) are nonstandard ellipsoid, which is realized …

Based on the engineering background of the Meishan iron mine with sublevel caving (SLC)
method, in this work, we adopted the method for identifying the shape of mined orebody (the …

The penetration of rock fragments of overlying strata causes advanced ore dilution during
drawing. The results of numerical and physical experiments showed that the proposed …

At present, when addressing the problem of fault stability in mines, most attention is paid to
the study of the impact of a single mining method on faults. In order to study fault stability in …

Reasonable delay time between blastholes is imperative in improving the blasting effect and
mining efficiency. At present, the research findings on the effect of inter-blasthole delay time …
