Abstract This study focuses on steeply inclined and extremely thick coal seams (SIETCS) characterized by immense thickness, a steep inclination of (87°), high horizontal stress. The geological conditions mining technology associated with SIETCS differ significantly from those generally seams, resulting in notable variations roadway stress distributions. On have predominantly examined the impact rock layers flanking bursts, limited emphasis roadways. employs comprehensive methods, integrating...
The steeply inclined and extremely thick coal seams (SIETCS) under the condition of gob filling frequently suffer from occurrence rockbursts. Figuring out mechanisms rockbursts this for taking targeted measures to mitigate rockburst hazards in SIETCS is great significance. Using typical with an average dip angle 87° at Wudong Coal Mine (WCM) as a case study, mechanical model elastic deformation energy (EDE) function “steeply suspended roof structure” was developed, influence factors were...
The presence of a high concentration Cl− in saltwater will erode the structure and facilities, reducing stability service life underground oil storage cavern. In order to reduce risk seawater intrusion, this paper studies prevention technology intrusion based on case study coastal large-span A refined three-dimensional hydrogeological model that comprehensively considers permeability coefficient partitions, faults, fractured zones are constructed. seepage fields risks reservoir site its...
