A novel evaluation method of mining goaf ground activation under high-speed railway load

Frontiers in Earth Science, 2022
With the continuous improvement of infrastructure, some high-speed railway lines will inevitably cross the goaf ground, and there is less research on the safety of high-speed rail construction in goaf ground.

Bat Colony and Cave Zone Shape Arthropod Assemblages in Levantine Caves

Insects
Caves are characterized by unique abiotic conditions such as limited light, and they therefore support distinct faunal assemblages that often include endemic species. Due to light limitations, photoautotrophic organisms are absent from many subterranean food-webs, which therefore predominantly rely on allochthonous nutrient sources.

Cyanobacteria and algae from biofilm at the entrance zone of Petnica Cave

Zbornik Matice srpske za prirodne nauke, 2021
The importance of biofilms in caves, the diversity of microorganisms in them, their mutual relationship and relationship with the substratum are among the advancing research topics in microbial biospeleology. This research is making contribution to the knowledge about biofilms at cave entrances and phototrophic communities in them.

Mechanical Model for Calculating Surface Movement Related to Open-Pit and Underground Caving Combined Mining

, 2023
Surface movement under the combined mining of open-pit and underground caving is the main problem affecting safe and efficient mining. Taking the combined mining of Dahongshan Iron Mine as an example, a mechanical model for calculating surface movement ...

Research on the characteristics of the falling behavior of mixed coal and gangue

Gong-kuang zidonghua
Traditional studies on the dynamic characteristics of coal flow during the top coal caving process, based on image detection technology, have primarily focused on specific-stage image analysis, lacking a comprehensive analysis of dynamic characteristics ...

Integration of the arts and biomedical engineering in innovative interdisciplinary anatomy education: The synthetic anatomy module

Anatomical Sciences Education, EarlyView.
Abstract The intersection of science and art has historically fostered innovation, yet the integration of creative arts into anatomy education remains limited. The Synthetic Anatomy module was designed to bridge anatomy teaching with creative design for bioscience and biomedical engineering students. This study evaluates the module's educational impact

Liner Behavior of a Tunnel Constructed Below a Caved Zone

KSCE Journal of Civil Engineering, 2018
Underground mining leads to deformation of the surrounding rock strata. Over time, this deformation tends to stabilize after mining has completed. However, ground movement can easily reactivated if another adjacent underground project is excavated nearby.
