| 中文摘要: |
| 陕西省洛南县镰子沟金矿成矿区带属小秦岭金矿带西段驾鹿矿田,为蚀变带型金矿,共获金资源量2373 kg,具备中型以上规模金矿床的成矿条件。通过矿区含水层、构造破碎带及地下水补、径、排规律,矿区水文地质参数及矿坑涌水量分析,说明构造破碎带导水是影响矿坑涌水的主要因素。地下水类型主要为第四系孔隙潜水及(风化)破碎带裂隙潜水,大气降水是矿区内主要的补给源。含水层弱富水,发生突水事件概率小,矿区水文地质条件简单。 |
| 英文摘要: |
| The Lianzigou gold deposit field located in Luonan county,Shaanxi Province, is situated on Jialu ore field, western part of the Little Qinling gold mineralization belt. The Lianzigou gold deposit belongs to the altered type gold deposit, and the proven gold resources of is 2373 kg. There is favorable metallogenic conditions in Jialu gold deposit field area for discovering medium-sized and large sized gold deposit. By systematic analysis on the aquifer, structural fracture zones and groundwater recharge and runoff discharge,hydrogeological parameters and water inflow in the mine, it is concluded that structure zones are the main factors of impacting water inrush, and groundwater types are Quaternary pore water and (weathered) fissure water filled in the broken zones. Atmospheric precipitation is the main water sources for supplying in the mining area, and the aquifer layer is weak to enrich water, thus the probability of water inrushing is small. Overall, the hydrogeological conditions is simple type in the mining area. |
