摘　　要：针对岩溶陷落柱导致的突水具有隐蔽性和突发性的特点,为了预防岩溶陷落柱突水,对岩溶陷落柱可能发育的区域加以预测。根据滕南矿区地质与水文地质资料,分析已揭露的陷落柱的分布特征,总结岩溶陷落柱的发育规律。结果表明:岩溶陷落柱分布和发育具有不均匀性,多发育在矿井浅部,以及富水性较强和强径流条件的区域;岩溶陷落柱发育主要受奥灰埋深、奥灰含水层的富水性、地质构造控水条件及奥灰地下水径流条件4个因素的综合控制。在此基础上,构建层次分析评价模型,采用专家打分赋权方法,对4个控制因素统筹考虑,预测未来可能发育岩溶陷落柱的区域,旨在控制和避免煤矿生产中揭露岩溶陷落柱或处理不当而造成灾害。As the water inrush caused by karstic collapse column has the characteristics of concealment and sudden,it is necessary to predict possible development area in order to prevent water inrush in karstic collapse column.Based on geological and hydro-geological data of the Tengnan mine area,the distribution characteristics of karstic collapse column have been revealed and the de-velopment law of the karst collapse column has been obtained.It has been shown that the distribution and development of karstic collapse column is inhomogeneous and is mostly developed in the shallow part of the mine and good water-abundance,developed structure and strong runoff zone.It follows that the development of karstic collapse column is mainly controlled synthetically by four factors,including Ordovician limestone depth,water-abundance of Ordovician limestone aquifer,geological structures con-trolling groundwater condition and Ordovician limestone groundwater runoff.Based on above study,an analytical hierarchy evalu-ation model is proposed and the method of expert ratings is aodpted.By taking four factors into consideration,we can predict the developmental area of karstic collapse columns in the future in Tengnan mine.It is of important value to control and avoid the ex-posed karstic collapse column or improper handling and cause disasters.
