| 摘 要： | 在全面分析大雁矿业集团公司雁南煤矿北二采区的水文地质条件及煤层开采矿井充水因素的基础上，计算了开采27^1号煤层时导水裂隙带发育高度．得出了北二采区各煤层工作面开采即不会受到上部砂砾含水层的影响，雁南煤矿铁路涵洞以西的胜利河冲击沟也不会受到北二采区的采动塌陷影响的结论。

| Abstract: | based on fully analyzed the hydrogeological condition and mine water filling factors, estimated water conducted fracture zone height activated by the mining of No.271 coal seam, worked out conclusions of coal seam working faces of the North No.2 winning district will not be impacted by upper granule gravel aquifer and the Shengli River alluvial gully at west of Yannan coalmine railway culvert will not be impacted by North No.2 winning district mining activated subsidence. |
