【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。
[Abstract]:In view of the hidden and sudden characteristics of water inrush caused by karst collapse columns, in order to prevent karst collapse columns from inrush water, this paper predicts the areas where karst collapse columns may develop. According to the geological and hydrogeological data of Tengnan mining area, The distribution characteristics of the exposed collapse columns are analyzed, and the development rules of karst collapse columns are summarized. The results show that the distribution and development of karst subsidence columns are uneven, mostly developed in the shallow part of the mine, and in areas with strong water-rich and strong runoff conditions. The development of karst collapse column is mainly controlled by four factors: the depth of Ordovician ash, the water-rich of Ordovician aquifer, the water control condition of geological structure and the runoff condition of Ordovician ash groundwater. By adopting the method of expert scoring and weighting, considering the four control factors as a whole, predicting the areas where karst collapse columns may develop in the future, the purpose of this paper is to control and avoid exposing karst collapse columns or improper handling in coal mine production to cause disasters.
