摘要
万象平原丰富的钾镁盐矿产资源正有待开发,正确选择开采方式将能最大限度地保护环境和提高资源利用率。针对盐类固体矿产的两种开采方式———坑道开采(旱采)和水溶开采(水采),分别从水文地质、工程地质和环境地质三个方面对矿床开采技术条件进行深入评价,研究确定了矿区的开采技术类型以及开采技术条件,并就旱采和水采条件分别进行对比分析,从中择优选取比较理想的水溶开采法———钻孔选择性溶浸法。
In Vientiane plain,plentiful K-Mg salt resources will be exploited.In order to protect environment and increase utilization as far as possible, a correct exploitation program must be selected. In thia paper,we profoundly evaluate the exploitation conditions in hydrogeology, engineering geology and environmental geology of this ore deposit, determine the technological type and condition of exploitation and correlate the conditions of dry exploitation with those of water exploitation.
