摘　　要：下石节矿井+950 m水平多个工作面开采中周期性异常涌水明显,根据矿井地质及水文地质资料分析,矿井+950 m水平工作面充水水源主要为顶板洛河组含水层水,充水通道为采动裂隙,在总结工作面涌水特征的基础上分析了离层涌水条件,矿井离层涌水主要受工作面采宽、采厚、洛河组含水层富水性、直罗组泥岩厚度影响,并以此为基础选取采厚、洛河组含水层富水性、直罗组泥岩厚度、直罗组泥岩厚度占比共4个主控因素,引入危险性指数SI作为指标,建立了离层涌水危险性评价模型,采用多源信息融合技术对+950 m水平进行了离层涌水危险性分区评价。The periodic abnormal water gushing is obvious in the mining of multiple working faces at+950 m level in Xiashijie mine.according to the analysis of mine geological and hydrogeological data,the water filling source of+950 m horizontal working face in Xiashijie mine is mainly aquifer water of Luohe formation,and the water filling channel is mining fissures.On the basis of summarizing the water gushing characteristics of the working face,the condition of water gushing from the separated layer is analyzed.Mine separated water gushing is mainly affected by mining width,mining thickness,aquifer richness of Luohe formation and mudstone thickness of Zhiluo formation.On this basis,four main controlling factors,namely mining thickness,aquifer water richness of Luohe formation,mudstone thickness of Zhiluo formation and proportion of mudstone thickness of Zhiluo formation,are selected,and the risk index SI is introduced as an index to establish an off-layer water gushing risk assessment model.The multi-source information fusion technology is used to evaluate the risk of off-layer water gushing at+950 m level.
