With the increase in mining depths, support problems of anchor such as roof accidents and
large deformation of soft rock are becoming more and more prominent. Whether the anchor …

Pretension is the pre-added axial tensile force on fully grouted bolt systems, which include
rock bolts and cable bolts. Although a series of studies via lab testing and analytical …

Based on the geological conditions of soft-rock roadway with a buried depth of 1336 m and
the data that are achieved by various experimental methods, the multi-factor coupling …

Modelling, experimental study, and field observation are prevailing research methods in
coal mine support application. Many criteria and rationales have been established to …

Roof cutting is an effective technique for controlling the deformation and failure of the
surrounding rock in deep gob-side entry. The determination of the roof cutting parameters …

Determining a suitable width of gob-side filling wall (GFW) is a major concern in the
application of gob-side entry retaining (GER) technology in highly gassy coal mines. This …

This paper presents an integrated investigation of the ground stability of a deep gateroad
with a 1 km burial depth based on a field test, case studies, and numerical modelling. In situ …

The coal wall, gob-side backfill, and gangues in goaf, constitute the support system for Gob-
side entry retaining (GER) in coal mines. Reasonably allocating and utilizing their bearing …

Pretensioned partially encapsulated resin bolting with mesh systems (PPERBMSs) are
commonly employed in underground mines, particularly for soft coal gateways requiring …

The anchoring capacity of the anchor cable is closely related to the bonding length and
radial pressure conditions. Through field pull-out tests, theoretical analysis, numerical …
