Basin Resonance and Seismic Hazard in Jakarta, Indonesia

Geosciences, 2018
We use earthquake ground motion modelling via Ground Motion Prediction Equations (GMPEs) and numerical simulation of seismic waves to consider the effects of site amplification and basin resonance in Jakarta, the capital city of Indonesia. While spectral

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

Deep Underground Science and Engineering, EarlyView.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

Evaluation of the CO2 storage potential in CO2‐enhanced oil recovery: A case study of the Subei Basin, Jiangsu Province, China

Deep Underground Science and Engineering, EarlyView.
CO2‐enhanced oil recovery (CO2‐EOR) is an economically viable carbon capture, utilization, and storage (CCUS) technique that is widely practiced and contributes significantly to the achievement of carbon‐neutral cities. However, few studies have been conducted on CO2‐EOR source–sink matching involving different emission sources, different carbon ...

Hydrogen sulfide in underground hydrogen storage sites: Implication of thermochemical sulfate reduction

Deep Underground Science and Engineering, EarlyView.
A one‐dimensional diffusion‐based mass transport model was built using PHREEQC to highlight the potential challenges posed by thermochemical sulfate reduction (TSR) in depleted gas fields. The results obtained indicated that the presence of iron minerals (pyrite and hematite) is crucial for H2S generation through TSR reactions.

Field investigation of grout propagation within a caving mass under flowing water conditions in a metal mine

Deep Underground Science and Engineering, EarlyView.
This study investigated the characteristics of two‐liquid slurry propagation filling of underground concealed spaces under flowing water conditions in metal mines using on‐site engineering tests. We proposed four different grout stratigraphic classifications, investigated four main factors affecting grout propagation, and summarized five different ...

Multi‐proxy reconstruction of the Holocene vegetation and land use dynamics in the Julian Alps, north‐west Slovenia

Journal of Quaternary Science, Volume 38, Issue 1, Page 107-122, January 2023., 2023
Abstract Small mountain lakes are natural archives for understanding long‐term natural and anthropogenic impact on the environment. This study focused on long‐term (last ca. 13 000 years) vegetation changes and sedimentary processes in the catchment area of Lake Planina pri jezeru (1430 m a.s.l.) by using mineralogical, geochemical and palynological ...
