陈集向斜为刘桥一矿的主体构造,刘桥一矿从1971年建井至今,在井下掘进生产过程中共揭露岩溶陷落柱7个,通过对岩溶陷落柱发育特征资料的收集整理,发现陷落柱分布具有一定的规律性。从构造力学、水文地质方面对岩溶陷落柱的成因进行了分析。
The Chenji syncline is the main structure of the Liuqiao No.1 Mine. Since the well was built in 1971 in Liuqiao No.1 Mine, seven karst collapse columns were exposed in the process of underground excavation. According to the collection and arrangement of the karst collapse column development characteristics, Subsidence column distribution has a certain regularity. The causes of karst collapse columns are analyzed from the aspects of structural mechanics and hydrogeology.
