Water-Inrush Risk Assessment of Roof-Confined Aquifer Strata Based on FAHP–RF Model in the Arid–Semiarid Ecotone: A Case Study of Zhuanlongwan Coal Mine
Water inrush poses a serious threat to the safety and sustainability of coal mining operations, particularly in arid–semiarid regions where confined aquifers overlie coal seams. Therefore, an accurate assessment of roof water inrush risk is essential to prevent water hazards on the roof. In this…

Sonic Dispersions of P-Waves of Two Types: Fractured Safaniya Sandstone
As P-waves propagate in fractured porous rock, fluid pressure in fractures may be distinct from that in the contiguous matrix; the fluid pressure differential can drive a viscous squirt between them, which substantially attenuates the waves. A double porosity model of P-waves is constructed based…

A High-Temperature Stable Weighted Self-Generating Acid System and Its Field Application in 10,000-Meter Ultradeep Reservoir Wells
Conventional acidizing systems for ultradeep carbonate reservoirs face dual challenges: rapid acid-rock reactions limiting penetration depth and severe corrosion of injection strings under extreme conditions. To address these issues, this study develops a high-temperature self-generating acid…

Modeling Full-Stage Rock Creep: A Perzyna Viscoplastic Approach Incorporating Damage and Strain Energy Theory
Under high-level stress, the internal damage of rock accumulates over time, leading to significant nonlinearity in creep. However, traditional linear element combination models struggle to describe the creep behavior of rock in the accelerated creep stage. The creep mechanism is analyzed from the…

Characterizing depth-dependent roof water abundance in underground coal mines using transient electromagnetic data
Coal mining is a major industrial activity in North China, where water inrush hazards pose a persistent threat to safe and efficient mining operations. Accurate identification of water-abundant zones in coal seam floors and surrounding strata is therefore critical for mine water-hazard prevention…

Field and Laboratory Investigation of Pore Structure Evolution in CO2-Injected Sandstone Aquifers: Implications for Injectivity
Geologic CO2 storage in saline sandstone aquifers is controlled in part by injectivity, because the ability to sustain a target storage rate affects both pressure management and the number of injection wells required. Here we examine the Shenhua CCS Demonstration Project in the Ordos Basin, China…
