摘　　要：矿井充水危险性预测是矿井水害防治的重要工作。通过锦界煤矿矿井水文地质特征的研究,总结了煤矿地下含(隔)水层的发育特征及其与煤层的4种空间组合关系。分析得出矿井的主要充水水源为直罗组风化基岩裂隙含水层,充水通道为煤层采后所产生的导水裂隙带,计算并实际验证了导水裂隙带发育高度。依据采动条件下隔水层隔水性的判据,预测圈定了3-1煤层采后地表松散沙层与风化基岩含水层遭受破坏有可能发生充水的危险地段及充水危险性。Prediction of water filling risk in coalmine is an important task for water hazard control. Through the study ofhydrogeological conditions in Jinjie mine, the development characteristics of aquifer（aquifuge） and its relationship withfour spatial combinations of the coal seams are summarized. the analysis shows that the weathered bedrock fractureaquifer of Zhiluo Formation is the main water filling source, and the water filling channel is the permeable fracture zoneafter the coal seam is mined out. The development height of water- conducting zone is calculated and verified. Accordingto water resisting property criterion of the aquifuge under the mining conditions, the possible water-filling section and thewater filling risk induced by the destruction of the surface loose sand layer and the weathered bedrock aquifer aftermining seam 3–1 were predicted. The research results have an important guiding value for mine water prevention.
