Using swarm intelligence optimization algorithms to predict the height of fractured water-conducting zone

Energy Exploration & Exploitation, 2023
The accurate calculation of the height of fractured water-conducting zone (FWCZ) is of great significance for mine optimization design, water disaster prevention, and safety production of the coal mines. In this article, a height-prediction model of FWCZ based on extreme learning machine (ELM) is proposed.

Transformation and upwelling of bottom water in fracture zone valleys [PDF]

, 2020
Closing the overturning circulation of bottom water requires abyssal transformation to lighter densities and upwelling. Where and how buoyancy is gained and water is transported upward remain topics of debate, not least because the available observations

Structural Analyses aiding Identification of Water Conductive Fracture Zones in Crystalline Rock [PDF]

ASEG Extended Abstracts, 2018
Development of hydraulic conductive zones in crystalline rock can result from a wide range of geological conditions which include primary structures, post crystalline tectonics, fluid solution and movement within a developing and eroding regolith. Crystalline rock areas mostly have low water resource potential due to inherent extremely low storage and ...
