摘　　要：为了对断层影响下的煤层开采顶板突水危险程度进行定量化评价,以AHP模型为基础,在采用构造发育程度、含水层厚度、砂泥比3个指标对岩层富水进行定量化评价的同时,依据断层规模、断层围岩岩性、断层力学性质3个指标对研究区内断层的导水性进行定量化评价,然后综合地层富水性和断层导水性建立顶板突水危险性评价模型,得出顶板突水指数,并依据顶板突水指数大小对顶板突水危险性进行分区。In order to quantitatively evaluate the risk of roof water inrush under the influence of faults in coal seam mining.Based on the AHP model,used the structure development degree,aquifer thickness,sand shale ratio 3 indicators to quantitatively evaluate the water rich strata.At the same time,considering the water conductivity of fault,according to the fault scale,the wall rock lithology of fault and mechanical properties of fault 3 indicators to quantitatively evaluated the water-flowing ability of the faults within the study area.Then,according to the water abundance and the water-flowing ability of the faults establishment of risk index model for roof water inrush and obtain roof water bursting index.Finally,according to the roof water inrush index,the risk of roof water bursting is divided.
