摘　　要：“防、堵、疏、排、截、监、探”是煤矿水害防治的、措施。梧桐182602工作面水文地质条件复杂,具有大采深、底板承压水压力大、构造发育底板破碎等特点,针对182602工作面注浆压力提高对注浆效果的影响,通过分析发现的问题,总结其中的规律,制定出相应的治理措施,达到最佳的注浆效果。"Prevention,blockage,dredging,drainage,interception,supervision,and exploration"are measures to prevent and control water damage in coal mines.182602 working face of Wutongzhuang Mine was complicated in hydrogeological conditions,with the characteristics of large mining depth,high floor confined water pressure,structural development and broken floor.Based on the effect of the grouting pressure improvement in grouting effect of the 182602 working face,the law was summed up,the corresponding governance measures were made to achieve the best grouting effect.

关 键 词：水害防治 底板水 注浆加固
