Evaluation of Water-Inrush Risk and Water-Preserved Mining Under Goaf Water

open access: yesWater
In coal seam mining operations, the presence of overlying water bodies presents persistent challenges, particularly during multi-seam extraction, where water accumulation in upper seam goafs requires careful management. This study examined the Lingzhida Coal Mine, focusing on the geological conditions of the 3# seam (upper) and the 15# seam (lower), as

Predicting Erosion-Induced Water Inrush of Karst Collapse Pillars Using Inverse Velocity Theory

open access: yesGeofluids, 2018
Although the impact of Karst Collapse Pillars (KCPs) on water inrush has been widely recognized and studied, few have investigated the fluid-solid interaction, the particles migration inside KCPs, and the evolution feature of water inrush channels ...
