TD 745
In order to prevent the roof water inrush in shallow coal seam mining in the west China,it is necessary to construct an accurate water inrush prediction model to provide effective guarantee for coal production safety.In this paper,the 2001 working face of Anshan coal mine was chose as the engineering background,with the analytic hierarchy process and grey relational analysis method as the theoretical foundation,on the basis of the selection hierarchy analysis,the weights of the influential factors were studied from five aspects:surface water catchment features,wateriness of the aquifer,water-resistant characteristics of aquiclude,combined influence of overburden and mining disturbance characteristics.Then the correlation degrees between water-inrush factors were calculated.Finally a prediction model on roof water inrush in shallow coal seam withintegration of qualitative and quantitative indexes was established.Further,combined with specific engineering parameters,we predicted the roof water inrush points and the water inrush risks.The results indicate that the risk comprehensive level of roof water inrush in 2001 working face is very low; however,the surface catchment characteristics and combined features of overlying strata corresponding inrush levels are relatively higher,showing that it is easy to cause water inrush when reaching the index thresholds.To avoid related disasters,the mine can strengthen the water quantity monitoring of surface water and underground water across the gully and low-lying areas in the rainy season,meanwhile,take advanced drainage and blocking measures to prevent roof water inrush.
