中文摘要：

为了研究影响陷落柱导水性的影响因素,以刘桥矿区、任楼煤矿的岩溶陷落柱为研究对象,从构造控制作用、陷落柱柱体充填物特征及奥灰含水层水压3个方面进行了对比探讨。结果表明：受构造控制作用,刘桥断层改变了刘桥矿区东侧地下水径流方向,同时陷落柱受后期构造扰动作用;受F2、F3、F16断层影响,任楼煤矿则形成了相对良好的地下水径流系统,有利于岩溶发育;刘桥矿区陷落柱柱体充填物中泥岩厚度比远大于任楼煤矿,且固结程度也更好,因此,对陷落柱的导水性起到了更好的抑制作用;刘桥矿区奥灰含水层水压低于任楼煤矿,其克服柱体充填物阻碍渗流的能力相比较弱,使得整个柱体导水的范围相比较小。

英文摘要：

In order to study the influencing factors of hydraulic conductivity of collapse columns,taking Liuqiao Coal Mine and Renlou Coal Mine as examples,comparison and analysis were carried out from three influencing factors,tectonic control,fillings characteristics of karst collapse columns and water pressure from Ordovician limestone. The following conclusions were reached as follow： influenced by tectonic control,the runoff direction of groundwater supply to Liuqiao Coal Field from eastern karst aquifer was changed by the Liuqiao Fault,and the karst collapse columns were affected by the disturbance of late structure; affected by Fault F2、F3、F16,tectonic movement in Renlou Coal Mine made good groundwater run-off environment which was helpful to karst development. The fillings in karst collapse columns of Liuqiao Coal Mine had much greater proportion of mudstone and better consolidation than that of Renlou Coal Mine,so the water conductivity was more suppressed in Liuqiao Coal Mine than Renlou Coal Mine.Water pressure from Ordovician limestone of Liuqiao Coal Mine was lower than Renlou Coal Mine,and the capability of groundwater seepage by overcoming the resistance of fillings in collapse column was lower in Liuqiao Coal Mine,so the range of seepage for the whole column was smaller.
