Water-rich assessment and water inflow prediction of coal seam roof aquifer
In order to further explore the water abundance and water inflow characteristics of coal seam roof aquifers,and provide safety guarantees for coal mining work,the article takes the problem of higher water inflow during the mining process of a certain coal mine as the research object.AHP Analytic Hierarchy Process(AHP)and the GIS-based multi-source geo-science information composite superposed"water abundance index method"are comprehensively applied to evaluate the wa-ter abundance of the coal seam roof aquifer in the coal mine.The"big well method"was applied to predict the water inflow,and the accuracy of the prediction method was confirmed.
