The gas in the goaf of a coal mine is difficult to extract compared to the gas in the roadway. Studying the flow pattern of gas in the goaf fracture field is of great significance for optimizing gas extraction measures and ensuring coal mine production safety. Taking a coal mining face in Shaanxi Province, China as the research object, a mathematic...

This study investigated the effect of reducing seepage under a hydraulic structure. This article aims to find positional equations for the control devices that reduce the seepage under the hydraulic structure. Using lengths and angles of sheet-piles under the hydraulic structure where the sheet-pile was placed up- and downstream, respectively, upon...

The study of the rainfall infiltration mechanism of unsaturated soil has always been a hot issue in the field of geotechnical engineering. It is worth studying which parameters should be introduced to characterize the infiltration characteristics of unsaturated soil in the calculation and analysis of rainfall infiltration. In this paper, the Fredlu...

We used high-resolution imagery within a Geographic Information System (GIS), free gas and porewater analyses and animal bulk stable isotope measurements to characterize the biotic and abiotic aspects of the newly discovered Vestbrona Carbonate Field (VCF) seep site on the Norwegian shelf (63°28′N, 6° 31′E, ∿270 m water depth). Free gas was mainly ...

Tires waste is an undesirable urban industry surplus that has grown worldwide yearly. Because of its seals, this material may be used in earth dams, one option for disposing of this waste. Since this is the main objective of this study, an experiment on a soil sample with various ratios of rubber powder has been conducted to better comprehend the i...
Seepage is the most important indicator in the safety assessment of embankments which requires continuous monitoring to maintain structural integrity. Punctual monitoring techniques for seepage in embankments can only provide limited information on the process. As the thermal behavior of embankments is affected by seepage, a continuous temperature ...

Isolated overburden grout injection (IOGI) is a green mining method to control surface subsidence. Slurry water significantly influences grouting effectiveness and mining safety. This study establishes a three-dimensional visualization experimental system for slurry “diffusion-bleeding-seepage” to investigate the seepage law of slurry water. The sy...
Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. Dams are therefore ...
With reference to earth pressure balance (EPB) shield tunnelling, the pressure infiltration of foam into saturated sand is investigated through model study. The model accounts for the companion liquid flow during the foam spurt that was experimentally measured in a previous paper. A micro-stability model is established to predict the maximum foam p...
