Study on the variation of the permeability coefficient of soil–rock mixtures in fault zones under different stress states

open access: yesDeep Underground Science and Engineering, EarlyView.
A study is carried out on the variation of the permeability coefficient of soil–rock mixtures in fault zones under different stress states. Abstract As the first gold mine discovered at the sea in China and the only coastal gold mine currently mined there, Sanshandao Gold Mine faces unique challenges.

Research on transparency of coal mine geological conditions based on distributed fiber‐optic sensing technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study, which focuses on geological hazards associated with coal mines, analyzes the types and sensing parameters of geological hazards caused by coal seam mining, summarizes the action fields related to these hazards in mining, and discusses the multi‐field sensing method of disaster characteristics associated with mining rock mass in conjunction ...

The effect of thermal–hydro–mechanical coupling on grouting in a single fracture under coal mine flowing water conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Higher temperature leads to a better relative sealing efficiency with a slow flow rate. Temperature change shows a negative correlation with the seepage pressure and the grouting pressure. The “equivalent grouting point offset” effect of grouting shows an eccentric elliptical propagation.
