摘　　要：岩溶陷落柱是我国华北煤田广泛发育的一种极富区域特色的地质现象,我国华北地区因陷落柱突水而发生的特大突水灾害较多。这些事故造成了国家财产的重大损失,严重威胁矿工生命安全,制约煤矿生产发展。分析岩溶陷落柱充填特征与堵导水,为煤矿陷落柱防治水提供科学依据,丰富煤层底板突水理论,具有重要的理论意义和社会经济效益。Karst collapse column is a kind of regional characteristic and extensive geological, phenomenon in north China coalfield. Thus there are much big water projecting accidents because of collapse column water projecting in north China. These accidents have caused the significant loss of national property, threatened seriously miner life safety and restricted production development of coal mine. The filling feature and blocking up or transmissibility of karst collapse has been Analyzed, thus science basis of prevention and cure collapse water for coal mine was offered. It also can rich projecting water theory of coal seam base plate, so it has important theoretical meaning and socioeconomic performance.
