Study on the Evaluation of Floor Water Inrush based on AHP and GIS
In order to evaluate the water inrush risk of the 6#coal seam floor in the study area,the AHP vulnerability index method is adopted.Since this coal seam is mined deep,the geological structure is complex,and the risk of floor water inrush is high.Four evaluation indicators are selected,and the weight analysis is carried out by using the AHP method.The thematic map of each evaluation index was created by using GIS technology,and the data were normalized and overlaid to obtain the vulnerability evaluation partition.Through the AHP-type vulnerability index method,considering the weight of each evaluation index,the degree of risk of water inrush on the floor is quantitatively evaluated.Combined with the application of GIS technology,the spatial distribution of evaluation indicators can be intuitively presented,which is helpful to identify potential water inrush risk areas.The research results provide a scientific basis for the vulnerability assessment of floor water inrush.Based on the overlay analysis of evaluation indicators,a vulnerability assessment zoning map is obtained,which can reveal the degree of water inrush risk in different regions.
