摘　　要：梧桐庄井田的煤系地层中发育有较多隐伏陷落柱,它们易导致奥陶系灰岩水的涌入而发生多次突水事故。为探明梧桐庄井田五采区发育隐伏陷落柱的分布规律,避免工作面误揭露隐伏陷落柱导致矿井水害发生,本文通过测区整体采用“两宽一高”设计,使用时频空间补偿法和全三维处理质量监控法进行高密度三维地震勘探。结果表明,梧桐庄井田五采区西南中部方向存有3个隐伏陷落柱异常体大致呈串珠状NE向分布,基本与F 1断层走向一致。There are many hidden collapse columns in the coal-bearing strata of the Wutongzhuang minefield,which are easy to cause the influx of Ordovician limestone water and multiple water inrush accidents.In order to find out the distribution law of hidden collapse columns in the fifth mining area of Wutongzhuang mine field,and avoid the occurrence of mine water disaster caused by the false exposure of hidden collapse columns in the working face,this paper adopts the'two wide and one high'design through the whole survey area,and uses the time-frequency space compensation method and the full three-dimensional processing quality control method to carry out high-density three-dimensional seismic exploration.The results show that there are three hidden collapse column anomalies in the southwest central direction of the fifth mining area of Wutongzhuang mine field,which are roughly distributed in a beaded NE direction,which is basically consistent with the trend of F 1 fault.
