This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

ObjectiveExtremely thick aquifers in mining areas typically exhibit strong heterogeneity and high water yield. Therefore, they are prone to cause severe water inflow in mines and induce water disasters, representing a ma...

To investigate the influence mechanism of roof pre-splitting blasting on overlying strata movement in automated roadway formation without coal pillars, the mechanical response characteristics of the bearing structure of ...

Abstract Occupational Health and Safety (OHS), which holds substantial importance due to its profound human implications and far-reaching economic consequences, requires effective management to minimize workplace acciden...

Abstract In Australian open cut coal mines, floor disruption blasting is emerging as a promising technique for mitigating low wall failures by disturbing the continuity of shear planes within weak geological layers. Howe...

Abstract The uncontrolled floor heave in gob-side entry retaining is the serious problem of underground coal mining. This phenomenon has gravely restricted the application of pillarless mining that has been increasingly ...

BackgroundThe surface subsidence induced by coal seam mining represents a continuous dynamic evolution process. Constructing a full-time perdition model for surface subsidence in goafs holds significant theoretical and p...

Abstract Jurassic sandy mudstone formations are common in the Ordos mining area, and the diagenetic period is relatively late. The lithological characteristics and creep mechanical properties of this formation form the b...
