摘　　要：山阳煤矿5^(#)煤层处于奥灰含水层带压开采区,矿井生产与开发面临的主要灾害为底板奥灰水。研究认为山阳煤矿底板奥灰含水层水害主控因素有4项,分别为奥灰含水层水压、奥灰含水层径流特征、底板有效隔水层厚度、构造复杂程度。采用AHP的多元因素融合量化分析底板水害主控因素,评估各主控因素的权重,构建5^(#)煤层底板突水危险性评价图,对山阳煤矿煤层底板突水危险性做出合理评价,评价结果为山阳煤矿5^(#)煤层开采提供了科学依据。The No.5 coal seam of Shanyang coal mine belongs to mining pressure under Ordovician limestone water-bearing layer,which major disaster was inrush from coal seam floor Ordovician limestone water.This research suggests the four main controlling factors of the disaster of Ordovician limestone water-bearing layer in Shanyang coal mine was the pressure of Ordovician limestone waterbearing layer,runoff characteristics of Ordovician limestone water-bearing layer,effective water-resisting layer thickness and structural complexity.Through multiple factors integration based on AHP quantitative analysis of main controlling factors,determines the influence weight of main controlling factors,drawing the picture of risk assessment method of water inrush from No.5 coal seam floor and puts forward the rational evaluation for the risk assessment method of water inrush from coal seam floor in Shanyang coal mine,which provides scientific basis for the mining of No.5 coal seam in Shanyang coal mine.
