| 中文摘要: |
| 为满足塞拉利昂南方省枫叶红铁矿矿山开采要求,采用1∶10000 矿区水文地质测绘、河流及泉调查、水文地质钻探及抽水试验等方法,对矿山进行了详细的水文地质调查研究。查明了主要矿体位于当地侵蚀基准面以下,含水层主要为松散岩类孔隙含水层、基岩风化裂隙含水层和基岩构造破碎带含水层3类,矿区所处分水岭地段属地下水的补给区,地下水的补给来源是大气降水及Moa河与Jala湖的侧向补给,矿床主要充水含水层富水性中等,补给条件好,水文地质边界复杂,水文地质条件属于第三型,即水文地质条件复杂的矿床。今后随着矿产的开采应加强水文地质研究工作的投入,为矿山建设及开采提供依据。 |
| 英文摘要: |
| In order to meet the requirements of mining and sustainable economic development of Funehun iron deposit in the southern province of Sierra Leone, the hydrogeological survey of the mine was carried out in detail by means of hydrogeological mapping, river and spring survey, hydrogeological drilling and pumping test in 1∶10,000 mining area. Find out the main ore body below the local base level of erosion, aquifer is mainly for the loose rocks, bedrock weathering fissure aquifer pore aquifer and three types of bedrock tectonic fracture zone aquifer, mining area locates the watershed area of groundwater recharge area, the replenishment source of groundwater, atmospheric precipitation and earth-sized river and lake Jala lateral supplies, the main water filling deposit aquifer water medium, condition good, complex hydrogeologic boundary, hydrogeological conditions belongs to the third type, namely the complicated hydrogeological conditions of ore deposit. In the future, with the mining of iron deposit, the investment of hydrogeology research should be strengthened to provide a basis for mine construction and mining. |
