摘　　要：为进一步探明葛泉矿2号煤层底板采动破坏规律,测定底板破坏深度,更好地指导安全生产,基于葛泉矿地质条件和生产情况,通过现场实地调查,采用理论计算和井下现场钻孔双栓塞压水试验法实测,综合确定2号煤层底板采动导水破坏带深度,分析总结底板导水破坏带发育规律,提出应对措施和方案,为葛泉矿的安全生产提供技术保障。In order to further explore the mining failure law of No.2 coal seam floor in Gequan Mine,determine the depth of floor failure,and better guide the safe production,based on the geological conditions and production conditions of Gequan Mine,through on-site field investigation,theoretical calculation and underground on-site drilling double-embolization water pressure test method were used to comprehensively determine the depth of mining water conduction failure zone of No.2 coal seam floor.Development law of floor water-conducting failure zone was analyzed and summarized,and countermeasures and schemes were proposed.The study provided technical support for the safe production of Gequan Mine.
