摘　　要：为了实现工作面开采过程中对煤层顶底板突水危险性进行动态评价,依据西北型、华北型煤矿区水文地质结构、突水主控因素、突水致灾模式、水害类型的分析,建立了水源、通道和采动三准则来表征煤层顶/底板突水危险源与致灾危险性之间的关联,构建了煤层顶/底板突水危险性的关键危险源的评价指标体系,将指标体系中随着工作面开采具有动态变化的指标因素(含水层水压、应力-应变、导裂带高度/破坏带深度)作为危险源动态特征辨识的目标,建立多场-多参数的工作面突水危险性动态评价概念模型,提出了矿井突水的临界判别准则,依托深度学习/强化学习的海量参数分析计算能力,为煤层顶/底板突水危险性动态评价分区提供理论支撑。In order to dynamically evaluate the risk of water inrush from the coal seam roof and floor during the mining of working face,according to the hydrogeological structure,main controlling factors of water inrush,water inrush hazard modes and water hazard type in Northwest China and North China,the relationship between the water inrush hazard sources in coal seam roof and floor and the water inrush risk was characterized by three factors:water flling aquifers,water flow channels and mining disturbance,and the index system of key risk sources was established.The index factors varying dynamically varying with mining excavation,such as aquifers'water pressure,stress-strain,height/depth of failure zone,were taken as the targets of dynamic characteristics identification.The multi-field and multi-parameter dynamic evaluation model of water inrush risk of working face was established,and the critical criterion of mine water inrush was proposed.With the massive parameter analysis and calculation capabilities based on deep learning/reinforcement learning,the result can provide guidance for dynamic evaluation zoning of water inrush risk of coal roof and floor and forecasting and warning of water inrush of working area.
