摘　　要：针对工作面上部老空区水量大、层间距小、水压高和疏放水时间长的特点,工作面施工前提前编制物探设计和施工要求,对排水系统进行改造,保证有足够的排水能力,采用多次疏水降压的方式降低水头高度,通过以上措施的制定和实施,确保疏放水工作的安全顺利开展,争取缩短疏放水时间,使矿井生产有序进行。For the working surface of large water,small layer spacing,high water pressure and long time,the working face construction premise preparation of geophysical design and construction requirements,the drainage system,to ensure enough drainage capacity,reduce the height of the head,through the formulation and implementation,to ensure the safety of drainage work,strive to shorten the drainage time,make the mine production orderly.

关 键 词：小间距 大水量 高水压 长时间
