| 摘 要： | 华北型煤田中发育的岩溶陷落柱是一种特殊类型的岩溶塌陷。本文在专题调查的基础上 ,总结了华北型煤田陷落柱的空间分布规律 ,初步提出了陷落柱宏观预测指标体系 ;从生产实践角度分析了影响陷落柱导水性的相关因素 ,讨论了三种与陷落柱有关的突水通道类型 ,并对陷落柱的鉴别及其与断层突水的区别进行了剖析。

| Abstract: | Karstic collapse posts existing in North China type coalfields is a special kind of karstic collapse. Based on the special investigation of collapse posts in coalfields of northern China, this paper summarizes their space distribution regularities, gives index system for macroscopic prediction of the collapse posts. By the view point of production, the authors analyze the factors related to water conducting behavior, generalize the method to determine the ground water runoff belt, discuss three types of conduits, and analyze the discrimination of collapse posts and difference between water bursting caused by collapsed posts and that caused by faults. |
