| 摘 要： | 磷石膏堆场特别是岩溶区堆场渗漏对地下水和地表水水质影响较大。根据现场连通试验、物探及钻探揭示资料分析，研究区主要有三种渗漏类型:裂隙型（双眼井泉）、裂隙-管道型（发财洞岩溶管道）和管道型（鸭草坝岩溶管道水系统）。天然不防渗条件下，库水通过地表落水洞、溶缝和溶隙等入渗地下水，产生岩溶渗漏。入渗补给独田地区的S1号泉、杨花冲地区的S23号泉、下摆郎地区的S13、S14号泉。其它泉水受隔水层的阻隔及地下水的补、排条件所限，没有受到污染。独田堆场运行后堆场存在渗漏情况，但是，防渗系统运行后渗漏的污染情况较之前有较为明显的下降。

| Abstract: | Leakage of phosphorus gypsum storage site especially in karst area has a great effect on groundwater and surface water quality. The methods of connective experiment, geophysical prospecting and drilling are integrated to give a comprehensive study. The main leakage types of the study area are fracture type (Shuangyanjing spring), fracture-channel type (Facaidong karst channel) and channel type (Yacaoba karst channel). Without the impermeable seepage-proofing, leakage to the groundwater will happen through aven doline, dissolved fracture and solution crack. The leakage will transport to S1, S23, S13 and S14 springs. Other springs will not be contaminated for the exitsing of aquitard layer. The leakage exists after the run of the storage site but the pollution of groundwater declined obviously after the run of seepage control system. |
