Research on the variation law and influencing factors of water inflow in deep water mines in Huize
As the Huize mining area extends deeper,the deep periphery faces safety risks such as"high water pressure and significant water inflow,"which can easily lead to water hazard accidents.To avoid these water hazard safety risks and ensure orderly progress of deep exploration and mining projects,this paper collects hydrological data and scientific research achievements from past years in the mining area.It discusses the im-pact of four aspects-meteorological hydrology,geological structure,aquifer characteristics,and engineering development-on mine pit water inflow.Using the Fuzzy Analytic Hierarchy Process(FAHP),a hierarchi-cal structure model is established with eight main controlling factors:atmospheric rainfall,karst,fracture structures,aquifer thickness,rock layer permeability coefficient,unit water inflow,mine depth,and mining area.The results indicate that above the erosion base level,atmospheric rainfall is the most significant factor affecting mine pit water inflow,while below the erosion base level,the weight values of various influencing factors are relatively similar.
