In the loose and fractured coal seam with particularly low uniaxial compressive strength
(UCS), driving a roadway is extremely difficult as roof falling and wall spalling occur …

Longwall mining is a widely used coal mining method in underground engineering, in which
a considerable roadway tunnelling is required. This makes it difficult for the roadway …

Strainburst is the most common type of rockbursts. The research of strainburst damage
mechanisms is helpful to improve and optimize the rock support design in the burst-prone …

With the deterioration of mining conditions, the stability of roadway has become an important
research topic for safe and efficient production in coal mines. To protect the gob-side …

The paper presents the study of the deformation processes development in unstable rocks of
the hanging wall during mining a thick steeply dip** ore deposit in the example of the …

Roadway stability in extremely soft coal mass is a typical challenge in deep underground
mines, as the most widely adopted support structure such as rock bolting, compound support …

The efficiency of coal mining is seriously affected by roadway stability, as large time‐
dependent deformation of roadway frequently occurs and needs to be maintained several …

Cemented paste backfill (CPB) is an eco‐friendly composite containing mine waste or
tailings and has been widely used as construction materials in underground stopes. In the …

The magnitude and frequency of induced seismicity increase as mining excavation reaches
greater depth, leading to the increasingly severe damage to roadways caused by high …

Pre-grouting as an effective means for improving the stability of roadways can reduce
maintenance costs and maintain safety in complex mining conditions. In the Guobei coal …
