Identification of main groundwater conduits and optimization of anti-seepage curtain schemes in karst water-rich mines
摘要
Abstract
In karst water-rich mines,the main groundwater conduits serve as primary sources and pathways for water inrush hazards,making their precise spatial identification critical for mine water disaster prevention,anti-seepage design optimization,safety assessment,and mining benefit evaluation.This study focuses on a gold mine in Hunan Province,employing a progressive multi-source data integration method that combines hydrogeological investigation,geophysical prospecting,borehole verification,and groundwater tracer tests to delineate the spatial distribution of main groundwater conduits.A high-resolution three-dimensional groundwater numerical model was constructed using the GeoModeller-FEFLOW coupling approach and calibrated against field observations.Systematic simulations of multiple anti-seepage curtain schemes were conducted to quantitatively evaluate their hydraulic control efficacy.The results show that compared to a fully enclosed curtain on the western side(Scenario Ⅱ),a locally installed curtain targeting only the main conduit zone(Scenario Ⅳ)reduces curtain construction volume by approximately 90%,while increasing the mine's normal water inflow by only 31%.This integrated workflow,which combines multi-level conduit identification with coupled numerical modeling,offers a replicable framework for hydrogeological investigations and water hazard mitigation in analogous karst mining environments.关键词
