| 摘 要： | 岩溶陷落柱作为华北煤田一种特殊的地质构造,已成为严重威胁矿井安全开采的重要因素之一。通过对范各庄煤矿矿井资料、地质勘探资料的搜集,以及对已经发现的陷落柱进行观测分析,得出陷落柱的发育规律,并讨论了陷落柱的形成机理,认为该区在总体轴向为北东向的开平复式向斜构造背景控制下,陷落柱的分布呈现北西向带状分布、成群出现的规律,主要受到奥陶纪灰岩、构造发育和地下水强径流带的控制。

| Abstract: | The subsided column,as a special geological structure in north Chine coal field,has become a serious threat to mine safety.In this paper,the development law of the subsided column was obtained by the collection of the mine data and geological exploration data in Fangezhuang Mine and the observation analysis of the found subsided columns,and the formation mechanism of the subsided column was discussed.It was found out that the subsided column presented the law of north-west zonal distribution and in groups u... |
