| 摘 要： | 本文阐述了华北型煤田内岩溶陷落柱形成的基本条件及其分布规律，依其导水性把陷落柱划分为三大水文地质类型，指出多数是隔水的，但若形成较新或处于强径流带及集中排泄带，可成为矿床充水通道，勿通奥灰水进入矿坑，发生突水淹井事故。对此进行了深入探讨，并提出相应的防治方法

| Abstract: | The basic forming coditions and distribution of the karstic collapse columns in coal field of North China type are discussed in this paper.Three hydrogological types of collapse columns are divided according to thir permiability.The study showed that most of the collapse collumns were impermible,and only those lately formed of formed in strong run off zone or in drainage concentrated zone could be the path of water bursting.Precautionary measures are put forward and discussed in this paper. |
