摘要:
滦县－滦南县段滦河冲积平原铁矿群司家营铁矿区、马城铁矿区、坎上铁矿区、常裕铁矿、高官营铁矿总储量达几十亿吨，均覆盖有巨厚的第四系含水体，水文地质条件复杂，一直未能开采，成为“大水呆滞金属矿”，被视为开发过程中可能对区域水文地质环境造成较大影响的大水矿区，列为限制开采区，至本世纪初才相继解限投产.通过对司家营铁矿北区、司家营铁矿南区、马城铁矿区、坎上铁矿区、常裕铁矿、高官营铁矿等6处矿山的水文地质条件的分析，论述了滦县－滦南县段滦河冲积平原的水文地质特征.
Abstract:The total reserves of the iron deposit group in Luanhe alluvial plain of Luanxian-Luannan section, including Sijiaying iron orefield, Macheng iron orefield, Kanshang iron orefield, Changyu iron mine and Gaoguanying iron mine, amount to billions of tons. All of them are covered with huge thick Quaternary water-bearing bodies. Mining is impossible due to complex hydrogeological conditions. Being watery unminable metal ore fields, they have been regarded as the water-abundant mining areas that the regional hydrogeological environment might be greatly affected in the exploitation, and labeled as restricted mining areas. It is not until the beginning of the 21st Century that these mines are put into production successively. By analyzing the hydrogeological conditions of the iron deposit group, the paper discusses the hydrogeological characteristics of Luanhe alluvial plain in Luanxian-Luannan section.
