Fault rock is a typical hazardous material of water–silt inrush during the excavation in
underground mines. To investigate hydraulic characteristics of fault rock during the water …

Abstract Evaluation of water inrush risk is becoming increasingly important as coal mining
activities reach greater depths. Hazard identification, as well as hazard analysis, is the first …

It is believed that underground longwall mining usually produces fractures in the
surrounding rocks. On the one hand, mining‐induced fractures not only degrade the strength …

Terahertz technology holds the potential for applications in identifying risks and
development stages of coal spontaneous combustion (CSC). However, one critical factor …

To mitigate water shortage, a few groundwater reservoirs are being built at the Daliuta coal
mine, Shaanxi Province China. It is essential to investigate the deformation, failure and …

A secondary fuzzy comprehensive evaluation system is constructed to evaluate the risk of
floor water invasion in coal mines. Four first-grade indices and 13 second-grade indices are …

Failure characteristics of the coal seam floor above-confined aquifer are the key to
understanding water inrush mechanism during mining. Due to the heterogeneity of coal …

Coal mining above a confined aquifer involves the risk of water bursting into the mining
excavation through fractured floor strata. Understanding the key mechanisms and processes …

CH 4 adsorption isotherms of kaolinite with moisture contents ranging from 0 to 5 wt% water,
the effects of water on maximum adsorption capacity, kaolinite swelling, and radial …

The field measurement of permeability within the strata affected by mining is a challenging
and expensive task, thus such tests may not be carried out in large numbers to cover all the …
