| 中文摘要:攀枝花市西区龙洞煤矿经过十余年的生产,不但在地下形成了较大范围的采空区,而且通过影响地下水形成了较大范围的疏干,致使矿区内大部分泉点断流.因而,为确定矿山地下水长期疏干对龙洞泉流域的影响程度,笔者通过比较水库水、大气降水、地下水与渗漏水之间的同位素特征,区分出了地下水的补给来源,并为查明本区的水文地质条件及确定矿坑地下水疏干的影响范围提供科学依据. |

| Isotopic Study of Groundwater Drainage in the Longdong Cave Coal Mine of the Panzhihua District |

| Abstract:After about ten years mining,a large mine void was formed in the subterranean Longdong Cave coal mine,and this condition resulted in the drying up of some springs due to large amounts of groundwater drainage.In order to understand the affect of mining on the Longdong drainage area,the authors made a comparative study of the environmental-isotope formation of 18O,δD and 3H from reservoir,precipitation,groundwater and infiltration water in the laboratory,and the results have revealed the recharge source of groundwater and provided some clues to the hydrogeological condition in this area and exat information on the groundwater drainage in the mine. |
