Deep 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.

Non-symmetry of a hydraulic fracture due to the inhomogeneity of the reservoir [PDF]
arXiv, 2016 It is usually assumed that hydraulic fracture has two symmetrical wings with respect to the fluid injection point. Hence, authors limit themselves to modelling of one half of the fracture. In our work we demonstrate that the case of a symmetrical fracture occurs only in a homogeneous reservoir with constant physical parameters and confining {\it in ...

Genesis and reservoir preservation mechanism of 10 000‐m ultradeep dolomite in Chinese craton basin
Deep Underground Science and Engineering, EarlyView.Potential exploration target stratum of 10 000‐m ultradeep dolomite in Sichuan Basin and Tarim Basin, China. Abstract The 10 000‐m ultradeep dolomite reservoir holds significant potential as a successor field for future oil and gas exploration in China's marine craton basin.

Deep Underground Science and Engineering, EarlyView.Fine modeling of a three‐dimensional fracture structure under dynamic loading of coal is carried out. The streamline distribution law of pressure and velocity field in the loading process of the coal specimen is analyzed, the absolute permeability of the coal specimen is calculated, and the feasibility of the pore network model algorithm and finite ...

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 1, Page 183-203, January 2023., 2023 Abstract Estimates of the earthquake ground motion intensity over a geographical area have multiple uses, that is, emergency management, civil protection and seismic fragility assessment. In particular, with reference to fragility assessment, it is of interest to have estimates of the values of different ground‐motion intensity measures in order to ...
