徐宿岩溶地块地表水贫乏,却蕴藏着丰富的地下水。由于浅层孔隙水资源有限,并已受到不同程度的污染,裂隙岩溶水成为良好的水资源宝藏。随着工业不断发展,急需开发岩溶水,旧水源地也要求扩大开采量。本区水文地质条件复杂,地下水动力特征难于摸清,因而难于对资源量进行较恰当地评价。本文仅根据该区已有的开采长期观测及勘察资料,分析岩溶水资源的特征及与孔隙水的关系,并对开采资源量的近似计算方法进行阐述,虽属概略却实际可行。
Xu Susan karst surface water shortage, but it contains a wealth of groundwater. As the shallow pore water resources are limited and have been contaminated to varying degrees, fractured karst water has become a good water resource treasure. As industry continues to evolve, there is an urgent need to develop karst water, and old sources of water also require expanded extraction. The hydrogeological conditions in this area are complex and the dynamic characteristics of groundwater are hard to find out. Therefore, it is difficult to properly evaluate the amount of resources. Based on the existing long-term observation and survey data in this area, this paper analyzes the characteristics of karst water resources and the relationship with pore water, and expounds the approximate calculation method of the amount of mining resources, though it is rough but practically feasible.
