Compaction and seepage characteristics of broken coal and rock masses in coal mining: A review in laboratory tests

Interpreting correlations in stress‐dependent permeability, porosity, and compressibility of rocks: A viewpoint from finite strain theory

“…The experiments involve subjecting rock specimens to diverse confining stresses and pore pressures, replicating the stress conditions in underground environment, [7][8][9][10] allowing for the measurement of rock properties such as permeability, porosity, and compressibility. [11][12][13][14] Existing models are either empirically established based on experimental results or theoretically derived using small deformation theory. [15][16][17][18][19] While these existing methods have gained successes in applications, it is still imperative to develop a unified law for describing the characteristics of stress-dependent properties.…”

Hydrogeological Investigation of a Goaf and Subsidence Area Based on a Ground-to-Air Transient Electromagnetic Sounding Method

“…The occurrence of water disasters in coal mines has persistently posed significant geological hazards that hinder secure coal production, with its influence being surpassed solely by coal and gas outbursts [27]. Amongst diverse manifestations of water damage, goaf water indisputably occupies a pre-eminent position due to its frequent incidence, resulting in substantial human casualties and property losses [28,29]. Especially during the rainy season, there is a temporal escalation of moisture within the goaf region, which intensifies the peril associated with the potential harm caused by excessive groundwater infiltration.…”
