Numerical back analysis is a valuable tool available to rock mechanics researchers and
practitioners. Recent studies related to back analysis methods focused primarily on …

Historically, the idea of designing and installing rockbolts in rockmasses can be traced back
to the construction of the Snowy Mountain hydroelectric scheme in Australia, which was …

The problem of shaft instability has always been a major difficulty in deep mining practices.
The shaft fracture has a high probability of being located near the aquifers and the soft–hard …

Although the design of underground structures is becoming increasingly dependent on
modeling-based analysis approaches, ground control systems continue to be designed …

Vertical shafts play an important role in the safe operation of mines. The stability of vertical
shafts has always been a difficult problem in mining engineering, especially with the …

During shaft construction using a shaft boring machine (SBM), the extrusion effect caused by
the thrusts of the shaft boring machine can lead to excessive radial deformation and local …

Abstract The conventional (σ 1> σ 2= σ 3) multi-step creep test and true triaxial (σ 1> σ 2> σ
3) multi-step creep test of Jinping marble with rectangular shape were conducted. In this …

Shaft stability plays an important role in mine safety. Most of the previous studies focused on
the stress analysis of shafts using monitoring data. Since the shaft wall state in the deep …

Damage to mine shafts located below thick loose aquifers, caused by coal seam mining, can
seriously affect the operational safety of mines. In view of such a problem, the …

With an increase in the depth of shafting and subsequent risk growth, it becomes necessary
to make a maximum accurate estimate of the actual stress–strain behavior of the shaft lining …
