The continuous large deformation of the surrounding rock during gob-side entry driving in a
1000-m-deep mine requires frequent renovation of the mining roadway, seriously restricting …

In response to the large-scale instability failure problem of designing coal pillars and support
systems for gob-side entry driving (GSED) in high-stress soft coal seams in deep mines, the …

In order to study the evolutionary law of roof migration on Gob-Side Entry Retaining, this
paper takes the gob-side entry retaining in the comprehensive mining face of the Ningtiaota …

In view of the low recovery rate associated with wide coal pillar and the strong strata
behavior associated with small coal pillar, the roof cutting pressure relief of small pillar in …

The soft-rock roadways in kilometer-deep coal mines are often damaged by large
deformation and have to be periodically expanded and repaired, which seriously restricts …

Mining in deep coal seams is characterized by high ground stress, often accompanied by
coal and rock dynamic disasters such as rock bursts. High-pressure water jet slotting …

Under double-seam mining, the main roadway surrounding rock is affected by the
superposition of the advanced stress of the two-seam coal working faces. The stress …

The accurate exploration and 3D quantitative evaluation of faults in deep coal-bearing strata
in complex structure areas is still significant technical challenge. This study improves the …

In order to solve the problems of serious deformation and difficult support of roadway
surrounding rock in the process of gob-side entry driving, taking 230,708 working face of …

In Datong mine, the extraction of coal resources faces challenges due to strong strata
behavior and significant deformation of gob-side roadways during working face extraction …
