中文摘要：

对岱庄矿已查明的陷落柱柱体样本分别采用了薄片鉴定、自由膨胀率实验,分析了陷落柱柱体成分与导水性的关系。结果表明,当陷落柱柱体胶结程度较好,并含有方解石脉充填、具有类似于泥石浆的成分、黏土矿物含量较多时,可以降低其导水性。

英文摘要：

With thin section identification and free expansion ratio tests on the composition of the body samples of collapse column found in Daizhuang Coal Mine, the paper analyzes the relationship between the body composition and the water conductivity of the collapse column. The conclusion is that the water conductivity of the collapse column will fall when the column body which is in higher-degree cementation and is filled with calcite veins has the composition similar to debris slurry and higher content of clay minerals.
