Structure and deformation measurements of shallow overburden during top coal caving longwall mining

International Journal of Mining Science and Technology, 2017
Mining induced pressures are strong and overburden failure areas are large in top coal caving longwall mining, which constrains high production and safety mining.

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Model Test of the Water and Sand Mixture Inrush in the Mining-Induced Caving Zone

Geofluids, 2022
In western China coal mines, the mining-induced caving zone is regarded as a main pathway for water and sand inrush mixture hazards. The paper experimentally studied the flow behavior and the mechanism of water and sand mixture through mining-induced ...

Prediction of the height of caving zone above the undercut in block caving mining method

Rock Mechanics Letters
The block caving is one of the most commonly used methods in underground mining of massive, low/high grades, and deep deposits. As a result of undercutting, caving occurs and propagates toward the upper part of the ore block. It is essential to predict the height of caved ore and its volume based on shape of the caved zone to make an economic decision.

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.

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.
