To explore the law of ground deformation from shallow-buried close-distance multi-seam
mining, an observation station was built in the Bulianta Coal Mine to measure and record the …

To date, research on the use of unmanned aerial vehicle (UAV) photogrammetry to monitor
deformations caused by underground mining has focused on the methods and accuracy of …

The implementation of roof bolt support within a coal mine roadway has the capacity to
bolster the stability of the encompassing rock strata and thereby mitigate the potential for …

Jurassic coal seams are a common geological feature in the mining areas of western China.
Deeply buried Jurassic coal seams were mined in the Hujierte mining area in western …

Backfilling mining is a green mining method. The rational design of the compressed ratio of
the backfilling body can reduce backfilling mining costs while avoiding mining-induced …

Sustainable development in coal mining requires a continuous and efficient method of coal
extraction. Research shows that gob-side entries retained through roof cutting retained gob …

In favourable mining conditions, in particular at the Starobinskoye potash deposit (Belarus),
longwall mining systems are used. They cause a high human-induced load on the subsoil …

This case study presents the verification of two surface subsidence prediction models for
longwall mining at depths greater than 400 m. The surface subsidence points were surveyed …

Coal is the main energy source in China, but its underground mining causes surface
subsidence, which seriously damages the ecological and living environments. How to …

The liquidation of underground mines by the flooding leads to movements of the rock mass
and land surface as a result of pressure changes in the flooded zones. The changes …
